Abstract

Oryctes rhinoceros is an important pest of various coconut and palm species. Studies on the bacterial gut microbiome of O. rhinoceros larvae and their potential use as producers of industrial enzymes are still limited. This study aims to examine the diversity and abundance of culturable bacterial microbiome in the gut of O. rhinoceros and their potential to produce protease and lipase. This study consisted of several stages, i.e., collection of O. rhinoceros larvae from coconut plantations; isolation of culturable bacteria from larval gut; protease and lipase enzyme activity assays; and partial characterization of culturable gut bacteria in terms of morphology, physiology, and biochemistry. There were seven bacteria that were isolated from the gut of O. rhinoceros, which were differentiated by their morphotype. The seven bacterial isolates also showed variations in physiological, and biochemical characteristics, and the larval guts were dominated by Gram-positive bacteria. The Shannon diversity index was 1.33, evenness was 0.682, richness was 7, and the abundance of each type of bacteria varied between 2x105 and 9.1x1010. Bacteria UBOG1, UBOG3, and UBOG5 were able to produce protease, but all seven bacteria were unable to produce lipase. Thus, bacterial isolates UBOG1, UBOG3, and UBOG5 are potential to be used in industry.

Abstract

Maize downy mildew disease in Java, caused by Peronosclerospora maydis, can cause yield losses of up to 100%. Disease management of downy mildew using synthetic fungicides has been reported to cause resistance to P. maydis. This study identified early fungicide resistance in P. maydis from several maize production centers in Java (Blitar, Kediri, Klaten, Cianjur, Garut, Jatinangor, Rancakalong, and Sukabumi) by examining fungicide sensitivity levels and detecting genetic variation. The study was conducted at the Laboratory of Biotechnology of Plant Protection, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Padjadjaran from November 2018 to August 2019. The results showed that isolates from Blitar and Kediri (East Java) indicated resistance to metalaxyl and fenamidone. While in general, P. maydis isolates from West Java and Central Java still have sensitivity to metalaxyl, dimethomorph, fenamidone, and oxathiapiproline. Oxathiapiproline was the most effective fungicide in damaging P. maydis conidia in all locations. Based on the results of molecular identification, there is intraspecies genetic variation based on phylogenetic analysis.

Abstract

Water scarcity is an extreme global concern due to changing climate and rapid population growth. Worldwide, freshwater sources are depleting and there is a need to implement water-conserving approaches in water-limited or arid areas for sustainable crop production. Therefore, this study aimed to investigate the impact of deficit irrigation on cucumber plant physiology, growth, and fruit yield traits grown under greenhouse conditions. The experiment was conducted in a complete randomized design with four water regimes, 100%, 80%, 60%, and 40% crop water requirement (ETc). Results showed that the highest plant leaf chlorophyll contents (43.2 µmol m-2), plant biomass (12.43 g), plant height (172.39 cm), number of leaves (19.85), fruit yield (2.49 kg), and total soluble solids (3.73 °Brix) were in plants irrigated at 100% level. In comparison, the lowest plant height (115.73 cm), number of leaves (15.77) and fruit yield (1.81 kg) were recorded at 40% irrigation. Results revealed that reduced irrigation regimes up to 80% or 60% have no significant inhibitory effects on cucumber agro-morphological traits. However, 40% of irrigation levels showed significantly reduced plant morphological and fruit yield traits. Overall, the result demonstrated that regulated deficit irrigation can significantly conserve water without negatively impacting cucumber yield.

Abstract

Pesticides are increasingly used to deal with crop-disrupting organisms. However, only 1% are on target, and the rest threaten agricultural ecology. This research aims to study the effect of Sub-bituminous coal (SC) on the change of negative charge activity (NCA) on two types of land, namely secondary forest (SF) and pesticide-contaminated horticultural land (HL-P). Two studies respectively used a completely randomized design (CRD) with three replications on two land types and five doses, namely: A = control or 0 t/ha [0 g SC/500 g soil]; B = 10 t/ha [2.5 g SC/500 g soil]; C = 20 t/ha [5.0 g SC/500 g soil]; D = 30 t/ha [7.5 g SC/500 g soil]; and E = 40 t/ha [10 g SC/500 g soil]. The results show that the effect of 40 t/ha SC can increase NCA on the surface of soil colloids (ΔpH) by 43% in SF and 23% in HL-P. The effect of 40 t/ha SC on the two types of land has a significant effect on increasing pH H2O, EC, CEC, and OM composition, respectively, by 0.70; 0.04 dS/m; 44.30 cmol(+)/kg and 7.60% in SF and 0.33; 0.01 dS/m; 26.89 cmol(+)/kg and 3.00% in HL-P, compared to the control.

Abstract

Salak (Salacca spp.) is a tropical fruit native to Indonesia that has various benefits for human health. Salak breeding programs to produce new superior varieties are constrained by the long-life cycle of the plant, making it difficult to select the desired traits. Few systematic literature reviews have been conducted on salak breeding. The present article was written to analyse the existing literature on application of plant biotechnology on salak breeding program. Guided by the PRISMA Statement (Preferred Reporting Items for Systematic reviews and Meta-Analyses) review method, a systematic review of the Scopus and Google Scholar databases identified 42 eligible related studies. The literature screening process was conducted using Mixed Method Appraisal Tool, whereas the bibliometric network analysis was conducted using VOS viewer software. Further review of these articles resulted in three main themes – genomics, metabolomics, and tissue culture. These three themes produced a total of eight sub-themes. The application of biotechnology on salak plant breeding are still limited, the genomic and metabolomic of this tropical fruit are still a mystery. Several future perspectives for salak’s breeding program includes deeper study on the plant’s genomic aspects, such as genotyping by sequencing, genome mapping, and development molecular marker assisted selection.

Abstract

Breeding activities for winged bean plants (Psophocarpus tetragonolobus (L.) DC.) necessitate genetic diversity from local varieties. Identifying winged bean lines adds valuable initial information for shaping policies in plant breeding. Before proceeding with varietal development, it is crucial to establish the ideal type (ideotype) for superior winged bean varieties. The primary objective of this research is to ascertain the idiotype for superior winged bean varieties. The research was conducted in 2023 at Universitas Brawijaya, Indonesia, and involves the evaluation of five improved lines. The initial evaluation focuses on qualitative and quantitative characteristics of ideotype. The second evaluation concerns winged bean seeds' ideal morphological and physiological qualities. The third evaluation assesses winged bean pods' ideal physical and organoleptic preferences. The research outcomes have yielded the ideal morphological characteristics for winged bean varieties. This idiotype will be the foundation for the direction and target of winged bean plant breeding efforts, among the lines evaluated. NSM2 exhibits ideal flowering time and pod length characteristics, and lines PTL and PTL display ideal pod forms. MML and PBL lines have flavors aligned with market preferences regarding organoleptic qualities. These lines will be further improved through crossing to develop ideal varieties.

Abstract

The gambir plant can serve as a raw material for botanical insecticides. Plant-based insecticides are made in nanoemulsion form to overcome the insecticide particle size problem. This study aims to obtain a gambir waste form that has the potential to be used as a botanical insecticide using nanotechnology. The laboratory experiments include preliminary and follow-up tests. The preliminary test involves testing each extract (liquid, solid, and raw gambir waste) at three concentrations using a completely randomized design with four replications. The follow-up test uses the residue method on leaves to test insecticidal activity. Creating nanoemulsion from gambir waste involves mixing organic and liquid phases through spontaneous emulsification. The insecticidal effectiveness of this nanoemulsion is tested on Croccidolomia pavonana. The results show that solid and liquid gambir waste has the potential to be used as alternative insecticides, which can influence the mortality of C. pavonana with an LC50 concentration of 0.22 (solid waste) and 0. 29 (liquid waste), while LC95 is 2.44 (solid waste) and 2.52 (liquid waste). The research promotes utilizing natural resources and innovative technologies, advancing environmentally conscious pest control methods, and fostering sustainable agricultural systems.

Abstract

Tana Luwu area owns a relatively high diversity and production potential of sago, but it has not yet been managed optimally. This study aims to identify and analyze the diversity of morphological characteristics and the production of various sago accessions in Tana Luwu. Based on morphological characteristics, the sago palm in Tana Luwu is divided into two groups by the presence of thorns on the rachis and petioles. The presence of thorns has the largest coordinate axis angles, representing a higher diversity distance than other morphological characteristics. Some accessions show very high production potential, with a total production of 476.66 kg per dry tree starch. The average sago production in the six accessions is 276.40 kg per dry tree starch. Accessions with a yield potential > 200 kg per dry starch are observed in Kapa, Uso, Kasimpo, and Sabbe. Therefore, sago in these accessions is potentially developed to obtain superior varieties. Two significant morphological characteristics that contribute to sago production are stem height (r = 0.73) and the number of leaves (r = 0.78).

Abstract

Massive production of watermelon is correlated with its nutritional value and attractive appearance. Intensification of plant breeding through polyploidization is of utmost importance in horticulture to improve productivity with desirable morphological traits. Colchicine is a common polyploid inducer with limitations, including effects on plant viability and high costs. Another anti-mitotic agent has been developed from Catharanthus roseus ethanolic extract, but the applicative provisions need further exploration. This research focuses on the efficacy and performance of biocatharantine and colchicine in improving ploidy levels with morphological evaluation on orange watermelon ‘Citra Laga’. Mature seeds were treated with 2% biocatharantine and 0.2% colchicine for 12 and 24 hours. Generally, major morphological traits are unchanged, with significant differences found only in the width of leaves and color characteristics. Flow cytometry is performed to assess the ploidy level of plant cells. Mixoploid plants containing 2C+4C+8C DNA are produced by colchicine, but the lowest germination rate is found to have a negative effect. Biocatharantine increases the peak intensities of tetraploid 4C DNA within mixoploid plants with minimum risk to plant viability. This research discovers the potential of biocatharantine as an anti-mitotic agent, with an evaluation of the octaploid success of orange watermelon ‘Citra Laga’ mediated by colchicine.

Abstract

The success rate of explant morphogenesis in plant breeding using tissue culture techniques is frequently plagued by browning due to the oxidation of phenolic compounds. The cumulated amount of reactive oxygen species (ROS) drives the oxidation of phenolic compounds. Melatonin is reported to take a part in modulating the regulation of antioxidant gene expression, reducing the accumulation of reactive oxygen species, and enhancing the efficacy of tissue culture. This study aims to determine the optimal melatonin concentration on the efficiency of plantlet regeneration and expression of the antioxidant resistance gene in rice callus. This study utilizes rice TN1, Gogo Niti II, Ketan Hitam, and Cigeulis cultivars. Melatonin at 0, 10, and 15 µM concentrations is supplemented in plantlet regeneration media. Rice antioxidant-related genes, Mn-SOD, Cu/ZnSOD, Cytosolic APX, CAT, GPOD, OsAPX, and OsCATA, expressed after melatonin supplementation. Melatonin concentration at 10 µM generates the highest expression of all tested genes in TN1 compared to other varieties. The cumulated amount of hydrogen peroxide (H2O2) shows that Melatonin has the potential to increase the proportion of plant regeneration in Cigeulis (90.48%) and Ketan Hitam (91.67%) varieties with a concentration of 10 µM and in TN1 (94.44%) and Gogo Niti II (80%) at a concentration of 15 µM.
