The induction of colchicine mutations is one method of breeding. PT Gunung Madu Plantations, for example, has induced mutations of commercial sugarcane (Saccharum officinarum L.) varieties, however, investigations on the impact of colchicine on stomatal characters have received less attention. Therefore, this study aimed to analyse the stomata character of 21 sugarcane mutants of the GMP3 variety at PT Gunung Madu Plantations, Lampung, Indonesia with a focused look at stomata aperture width, stomata length and width, number of stomata, stomatal density, and stomata index. The collected data were analysed using cluster and Principal Component Analysis (PCA) through MVSP software. This study showed that all GMP3 mutants had Graminae-type stomata. In terms of stomata length and width, the average size of the GMP3 variety mutant was greater than that of the control. The diversity of stomata characters is fairly high due to differences in stomata size between GMP3 and control mutants. With a similarity index of 0.20, the phenetic analysis of 21 mutants of the GMP3 variety revealed that the relationship between mutants and controls was getting further. A six-character principal component analysis revealed that axis I's total variation accounted for 40.54 percent of the variation and had an eigenvalue of 2.43, whereas axis II's contribution to the variation was 19.02 percent and had an eigenvalue of 1.14. The findings indicate that stomata are excellent taxonomic evidence for identifying and analysing sugarcane varieties induced by colchicine-induced breeding.

Publisher : Malikussaleh University, Aceh, Indonesia

Odontoglossum ringspot virus (ORSV) is a orchid virus which infection most widely reported and has spread widely in the world, including in Indonesia. Viral infections can degrade the quality of the orchid plant so it is economically detrimental. To study a disease infection, identification is carried out first to determine the most appropriate method of control. These identification techniques include variations in infection symptoms, host range testing, testing of viral titers, observation of particle morphology, genome detection, and analysis of DNA and amino acid sequences. Efforts to control disease can be done through preventive and eradicative actions chemically, biologically, and based on artificial intelligence.

Liwa Botanical Garden is located in West Lampung Regency which has an area of 86.6 hectares and is one of the conservation of ornamental plants that presents the flora of the Bukit Barisan Selatan National Park. One of the flagship collections of this botanical garden is a native orchid. Disease infection is still a major obstacle in the cultivation and development of native orchid potential at Liwa Botanical Garden. Based on the results of previous studies, it is known that several individual natural orchid collections from Liwa Botanical Garden showed symptoms of fungal disease infections. Disease infections can inhibit plant growth and resistance and reduce the aesthetic value periodically. Symptoms of infection include necrotic patches on the upper surface of the leaf. This research was conducted to determine the identification of diseases and efforts to protect native orchids against fungal infections at Liwa Botanical Garden through a collection of samples that showed symptoms of infection, analysis of disease symptoms, and analysis of disease resistance levels. The results showed that the response of the native orchid at Liwa Botanical Garden to fungal infections was showed symptoms of wilting in the leaves, namely in the orchids Eria sp., Dendrobium sp., and Cymbidium sp. turns black on the edge of the leaf, Thrixspermum sp. The type of orchid most commonly infected with fungus is Cymbidium sp. a total of 8 samples, and Thrixspermum sp. 3 samples, Eria sp. as many as 4 samples, Dendrobium sp. and Calanthe triplicata as many as 6 samples. The type of native orchid that is most susceptible to fungal infections is Dendrobium sp. and Eria sp. with disease intensity of 74.11% and 22.3%. The results of this activity are expected to be basic information in efforts to protect plants against diseases to support the application of conservation of native orchids on Liwa Botanical Garden.

Indonesia has a tropical monsoon-type climate which suitable for agriculture and plantations. One of the main centers of orange fruits (Citrus sp.) production in Indonesia and become the top ten with the largest production is in South Sulawesi. Farmers commonly cultivate siam oranges (Citrus nobilis). Lime (Citrus aurantifolia) has not yet become the main production, which is inversely proportional to the high demand in South Sulawesi. This study aims to determine the ability of bio-catharanthine as a polyploidy agent against the phenotype of the familia Rutaceae cultivated in South Sulawesi. The research was carried out in Laboratory of Genetics and Molecular Biology, Department of Biology, Universitas Islam Negeri Alauddin Makassar using randomized complete block design consisted of two conditions (bio-catharanthine concentration including C1 = Bio-catharanthine 0.05%; C2 = Bio-catharanthine 0.075%; C3 = Bio-catharanthine 0.1% and immersion time including T1 = 3 h; T2 = 6 h). Phenotypic observations include plant height, the number of leaves and nodes, the length of roots, and the number of roots per shoot. The results of the study showed that the bio-catharanthine immersion of 0.05-0.075% for 6 hours in Rutaceae had a significant effect on their phenotypic characters.

Dendrobium is one of the genera of the third largest Orchidaceae family which reaches about 1184 species in the world. In Indonesia, this genus of orchids is a wealth of genetic resources that are abundant in the Eastern region, such as Papua and Maluku. These genetic resources have not been optimally utilized as elders in crossbreeding to produce offspring that have characteristics according to what consumers want. Due to the limitations of these morphological characteristics, another character is needed that can support the systematics of orchids, namely molecular characters. Plant kinship analysis can use molecular characters in the form of DNA strands that can overcome the weaknesses of morphological data that are known to have limitations and tend to be influenced by the environment. This study aims to analyze the kinship of several types of Dendrobium based on the rbcL gene and add to the basic data source of germplasm from the genus Dendrobium. The samples used were nucleotide sequences of 11 nucleotide sequences consisting of 10 types of Dendrobium (D. anosmum, D. jinghuanum, D. catenatum, D. nobile, D. jenkinsii, D. pahangense, D. nobile, D. pulchellum, D. fimbriatum, and D. pulchellum) which is used as an in group and 1 species of the genus Phalaenopsis namely Phalaenopsis equestris which is used as an outgroup. The results of Dendrobium kinship analysis with an in silico based rbcL gene molecular approach show that species in the same genus are not necessarily closely related. The species that is a member of the out group is Phalaenopsis equestris,. Phalaenopsis equestris forms its own tree branches, while the other 10 species are on the same phylogeny tree branches.

Dendrobium is the second-largest family of flowering plants in the world. There are several classes of Dendrobium, which usually identify by its, including leaves and flowers. Due to the similarity of its characteristics, identifying orchid types is complicated and usually can only be done by an expert. Moreover, those characteristics are typically non-deterministic; examining the orchid species is very challenging. This research aims to develop a novel fuzzy-based system to identify the species of orchid based on unprecise existing leaf characteristics. We used the main characteristics of Dendrobium leaves, including shape, length, width, and tips of the leaves. Based on the information from the expert, we develop the membership for each class of Dendrobium. By adopting this knowledge, we develop the system by using compatible programming with this case, and Borland Delphi as complex application development. The experiment is done by using 200 real datasets from the Liwa Botanical Gardens, West Lampung Regency, Lampung Province, Indonesia. The results are compared with those given by a Dendrobium expert. A confusion matrix is a valuable evaluation tool for measuring the performance of classification models. From the above results, we can determine the confusion matrix and calculate the TP (True Positive), TN (True Negative), FP (False Positive), and FN (False Negative). The confusion matrix given from the experiments is shown in Table 6. This indicates that the system can provide the same results as experts recommended. It is shown that the system can identify orchid types with an accuracy value of 94,6 %. Thus, this system will be beneficial for automatically determining the orchid genus.

Sugarcane (Saccharum officinarum L.) requires sufficient a water supply to produce optimal productivity. The selection of the superior varieties of sugarcane that are tolerant to drought can be done by molecular detection of the presence of the pyrroline-5-carboxylate synthetase (P5CS) gene. The research is aimed at molecular detection of P5CS gene in a commercial varieties at PT Gunung Madu Plantations (GMP), Indonesia that are potentially drought resistant. Similar research has never been conducted at PT GMP, as evidenced by the absence of official publications. The varieties used are GMP 3, GMP 5, RGM 06-654, PS 864, RGM 08-1026, PSJT 941, RGM 01-1834, GP11, RGM 07-099, and RGM 02-108. The research phases include DNA isolation, quantitative and qualitative DNA amplification, and PCR product visualization. Molecular data analysis is based on DNA band scoring results in the form of binary data which is then used to calculate the level of polimorphism information content (PIC) on the primary data used. The results of the study showed that nine out of ten varieties had P5CS-specific band sizes of ±167 bp, namely GMP 3, GMP 5, RGM 06-654, PS 864, PSJT 941, RGM 01-1834, GP 11, RGM 07-099, and RGM 02-108. A total of four of the nine varieties showed P5CS gene band thicknesses of RGM06-654, PSJT 941, PS864, and RGM 01-1834 which indicates the selected varieties most resistant to drought. The result of the PIC calculation has a value of > 0.25 which indicates the primary P5CS used is quite informative. The molecular detection was continued on one selected variety is PSJT 941, which showed that the relationship analysis of P5CS gene shows close affinity with the isolates from China and Bogor.

Cayenne pepper (Capsicum annuum L.) is a horticultural crop of significant economic importance. One of the major threats to its cultivation is the Cucumber mosaic virus (CMV), which can cause severe yield losses and crop failures. This study aimed to isolate weak CMV strains from natural populations of cayenne pepper, characterize their molecular properties, and evaluate the effectiveness of cross-protection conferred by weak strains against superinfection by virulent CMV strains. The research was conducted in three stages: virus isolation, molecular characterization, and evaluation of cross-protection effectiveness. Data analysis was performed using the MEGA v.11.0.11 software and analysis of variance (ANOVA). The findings identified the C1 isolate as a highly virulent CMV strain. Molecular analysis of naturally infected samples confirmed the presence of CMV through the amplification of specific DNA bands. Inoculation tests revealed distinct differences between weak and malignant strains, particularly in symptom severity and molecular characteristics, such as genetic distance. Furthermore, the weak strains demonstrated a protective effect, significantly reducing the infection rate of virulent CMV strains. This was evidenced by variations in symptom expression, disease severity, plant resistance, chlorophyll levels, carbohydrate content, and peroxidase enzyme activity. These findings highlight the potential application of weak CMV strains in developing disease management strategies for cayenne pepper cultivation.

Native orchid is one of Indonesian natural resources which play important role as parental materials in breeding program. Virus infection is one of the limiting factors in the cultivation of orchid. The purpose of this study was to detect Odontoglossum ringspot virus (ORSV) from native orchid. Symptomatic orchids were collected from 5 botanical gardens, i.e. Bogor, Cibodas, Purwodadi, Balikpapan, and Enrekang Botanical Gardens. Detection and identification was conducted by serological method using ORSV specific antisera, followed by RT-PCR and DNA sequencing. The serological test showed that 5 samples gave positive reaction against ORSV antiserum, i.e. Phalaenopsis amboinensis (KRB2) and Phalaenopsis amabilis (KRB12) from Bogor Botanical Garden, Phalaenopsis amabilis (KRP18) and Dendrobium salacence (KRP20) from Purwodadi Botanical Garden, dan Phalaenopsis modesta J. J. Sm. (KRBp5) from Balikpapan Botanical Garden. RT-PCR of the 5 samples using specific primer of ORSV coat protein gene was successfully amplified fragment DNA with size ± 474 bp. Homology analysis of those 5 ORSV isolates showed the highest index similiarity of 99.8% with corresponding sequences from 14 other ORSV isolates. Phylogenetic analysis indicated that ORSV KRB2 and KRP18 isolates was clustered in a separate group far from ORSV isolates in other countries. This is the first report of ORSV infection on native orchids collection from 5 botanical gardens in Indonesia.
