Abstract

Abiu (Pouteria caimito Radlk.) is a plant of Sapotaceae family that can be consumed fresh, processed, or as a medical product. The fruit and leaves of this plant contain bioactive compounds. This research aims to inform the interaction between leaf:fruit ratio treatment and foliar fertilizer on the quality of the abiu fruit. The study was conducted at Kebun Balungbang Jaya, Dramaga, Bogor, West Java Province, from July 2022 to November 2022. The experiment used a factorial split plot design. The main plot was a leaf:fruit ratio treatment (N1, 45 leaves:1 fruit, and N2, 30 leaves:1 fruit) on each tertiary branch, and the tiller plot was foliar fertilizer (P1: 1 g L-1, P2: 2 g L-1, and P3: 3 g L-1), which consisted of 3 replications. The results showed that treatment of the leaf-fruit ratio and foliar fertilizer did not affect the quality of the abiu fruit. The interaction between leaf:fruit ratio and foliar fertilizer had a significant effect on ATT, as indicated by the lowest acidity value in the leaf:fruit ratio treatment of 45:1 and a fertilizer concentration of 1 g L-1 with a value of 0.12% but has no significant effect on the external and internal quality of other fruits. Keywords: Bioactive compounds, sapotaceae, tertiary branch, titratable acidity

Abstract

Durio testudinarius, known as Durian Kura-Kura, is a native Bornean durian species in the Malvaceae family with fruit at the base of the main stem. Recent advances in genomic-based next-generation sequencing are being used to conserve germplasm and enhance plant breeding. This method rapidly and cost-effectively sequences plant genomes, allowing for simple sequence repeat markers to be constructed in silico. This study aimed to design and evaluate novel, simple sequence repeat markers utilizing next-generation sequencing microsatellite data of D. testudinarius. A total of 20 sequences containing di-, tri-, tetra-, and penta-nucleotide motif repeats were selected and designed to generate primers using Primer3 online software. The PCR results of the twenty primers tested on D. testudinarius and 19 genomic DNA samples of species from the Malvales order showed successful amplification. These newly developed simple sequence repeat markers are crucial for genetic population analyses, determining population structure, and enhancing plant breeding programs and conservation strategies for D. testudinarius and its relative's germplasm resources.

Abstract

Sengon (Falcataria falcata (L.) Greuter and R. Rankin) plantations in Indonesia are threatened by attacks from Boktor stem borers and gall rust disease. Controlling pests and diseases is difficult therefore, planting resistant trees obtained from tree selection programs is necessary. Currently, genomic breeding often incorporates GWAS, which uses thousands of SNP markers to identify markers with significant associations with the traits studied. This study aimed to bypass such expensive studies by identifying and developing SNP markers from sequences of putative resistance genes to Boktor stem borer and gall rust disease, identified from sengon transcriptomic data analysis. A total of 496,194 putative SNP sites were identified from transcriptomic sequences using the SAMtools and BFCtools programs, of which 119 SNP sites were associated with resistance genes. Of the 101 non-synonymous SNPs selected, only 12 were located in the conserved domain of each gene and were used for primer design. Of the 13 primers designed, only 10 were successfully amplified. Validation of 10 developed SNP markers on 100 sengon accessions using the HRM method confirmed a significant association between SNP markers and resistance traits, with a -log 10 (P-value) between 10.49 and 16.63. A few SNPs markers developed from putative resistance gene sequences are associated with resistance traits in sengon. Therefore, the SNP markers could be applied in selection programs for sengon trees resistant to Boktor stem borers and gall rust disease.

Abstract

Tomatoes are a widely produced and consumed fruit-vegetable belonging to the Solanaceae family. It contains minerals, vitamins, essential amino acids, sugars, and fiber. Micro-Tom is a wild-type cultivar from a cross between the Florida Basket and Ohio 4013-3 cultivars. Micro-Tom has two mutant types, the iaa9-3 and iaa9-5 mutants, which exhibit strong parthenocarpic properties. It is classified as a mutant tomato due to a mutation in the IAA9 gene, which belongs to the Auxin/IAA (Indole-3-Acetic-Acid) gene family and plays a role in suppressing the endogenous auxin signal transcription pathway. Using artificial light in cultivation techniques shortens the plant cycle and accelerates the juvenile phase. This study aimed to investigate the morphological, physiological, and production responses of Micro-Tom tomatoes to supplemental LED lighting. The research was conducted at the Leuwikopo experimental field of IPB University from March to November 2023. A completely randomized design was employed, with two factors (LED spectrum and Micro-Tom genotyping) and nine replicates. The study also examined the potential benefits of combining polychromatic and monochromatic light-emitting diodes (LEDs). The response of Micro-Tom tomatoes to artificial lighting with purple and white LEDs did not show significant differences in growth and production parameters. However, significant differences were observed between the tomato types, specifically between the Wild-type and the iaa9-3 mutant. No significant differences were found in LED treatment or Micro-Tom genotype for physiological parameters such as chlorophyll content and glucose-fructose levels. Regarding fruit quality, no significant differences were observed for parameters such as total soluble solids (TSS, Brix) to total titratable acidity (TTA, acidity), glucose and fructose, and malic acid. The LC-MS/MS analysis of leaves exposed to purple LED light revealed a profile dominated by secondary metabolites from the fatty acid compound group, suggesting the potential benefits of this lighting combination. In conclusion, using LED lights can accelerate the plant life cycle and shorten the juvenile phase, as evidenced by the first flower emergence, which occurred 20 days after transplanting (DAT) in the wild-type genotype and 16 DAT in the mutant genotype.

Abstract

Kecapi (Sandoricum koetjape Merr.) is a tropical fruit species that belongs to the Meliaceae family. Kecapi trees require 5-7 years to produce fruit when grown from seeds, necessitating efforts to accelerate their growth, including through the modification of light. This research aimed to study kecapi’s morphological, physiological, and anatomical responses to light spectra and intensities from light-emitting diodes. The experiment was designed using a two-factor, completely randomized design (CRD), namely LED light spectrum (white and purple) and light intensity (2 and 4 lights). The result showed that morphological and vegetative growth were significantly affected under the high-intensity purple LED treatment. The low-intensity purple LED treatment increased stomatal conductance and chlorophyll-b synthesis. The transpiration rate was highest under the high intensity white LED treatment. Low-intensity white LED treatment only increased the abaxial stomatal aperture. As the intensity increased, it also increased N-Total content but decreased micronutrient levels in the leaves.

Abstract

Macassar ebony (Diospyros celebica Bakh.) is an endemic tree species native to Sulawesi. To date, there are limited comprehensive publications regarding its genome assembly. In this study, we employed paired-end libraries of HiSeq 4000 Illumina, generating 141.2 million paired-end reads (42.4 Gigabases). Our analysis revealed the presence of 950,081 Scaffolds, with an N50 value of 6,023. Notably, BUSCO analysis identified 183 (12.7%) complete and single-copy BUSCOs (S), as well as 9 (0.6%) complete and duplicated BUSCOs (D). Furthermore, we identified 12,890 microsatellites within the Macassar Ebony genome. These microsatellites encompass 14 dinucleotide SSR motifs, 12,090 trinucleotide SSRs, 780 tetranucleotide SSR motifs, and 6 pentanucleotide SSRs. This dataset represents a valuable resource for assessing Macassar Ebony genetic makeup in its natural habitats and for subsequent analyses of the Macassar Ebony genome.
