Microsatellite (SSR) markers were employed to investigate the genetic diversity within a collection of durum wheat germplasm. A total of 41 landraces originating from geographically diverse regions—including Turkey, Lebanon, Morocco, Ethiopia, China, Kazakhstan, and Mongolia—were initially genotyped using 27 SSR markers selected to represent the whole genome. Of these, 7 markers failed to produce amplification products despite repeated attempts; therefore, 20 SSR markers were retained for further analysis. Among these, 17 loci were polymorphic and 3 were monomorphic. Analysis of the 17 polymorphic loci revealed a total of 67 alleles, with allele numbers per locus ranging from two to seven and an average of 3.94 alleles per locus. The polymorphic information content (PIC) values varied from 0.071 (Xgwm371) to 0.647 (Xgwm120), indicating differences in marker informativeness. Cluster analysis grouped the landraces into four genetically distinct clusters, demonstrating a clear relationship between genetic variation and geographic origin. In general, landraces from Africa and Western Asia exhibited higher genetic diversity compared to those from Central and East Asia. These results highlight Western Asia, Africa, and particularly southeastern Turkey as important centers of genetic diversity for durum wheat.

Cotton fiber development is a complex process regulated by multiple networks that involve various transcription factors (TFs). Recent studies (2020-2025) have elucidated the roles of TFs through silencing and overexpression experiments in cotton plants. We conducted a literature search in NCBI using the keywords ‘transcription factor, fiber elongation, cotton plant’ to identify relevant studies. This review focuses on studies published between 2020 and 2025 that were selected for review. We discussed various TFs and molecular mechanisms leading to altered fiber length. The research works included various analyses of transcription factors, genes, proteins, and metabolites as well as fiber quality results. The reviewed data highlight the complexity of fiber development networks, which involve extensive crosstalk among regulatory pathways. Despite the complexity, many novel TFs, modules, and tandems that participate in fiber elongation have been found. Their positive or negative regulatory roles in fiber formation stages promote a more profound understanding of fiber initiation and elongation.

Patchouli is a plant that produces essential oil. One problem with patchouli is that production remains low due to virus attacks. To address this issue, virus-free seedlings can be produced through tissue culture. This measure requires examining the effectiveness of patchouli regeneration in vitro through histological observations and acclimatization, in as much as effective propagation supports healthy seedlings. The purpose of this study was to determine the optimal propagation for Aceh patchouli via in vitro propagation, through histological observation. It investigated the optimal acclimatization for patchouli to assist patchouli adaptation. The study was carried out in several stages, starting from shoot multiplication, root induction, and acclimatization. Shoot multiplication was carried out on MS medium supplemented with BAP : 0.25 mg/L, 0.50 mg/L, 0.75 mg/L, 1.00 mg/L, 1.25 mg/L, and 1.50 mg/L. Root induction was carried out on MS medium supplemented with NAA : 0 mg/L, 0.2 mg/L, 0.4 mg/L, 0.6 mg/L, and 0.8 mg/L. Finally, the acclimatization was performed on compost under covering treatment. The results demonstrated that the best shoot multiplication, taking place in 6.3 days, was obtained through the 0.25 mg/L BAP treatment. This treatment resulted in the highest shoot proliferation, with a mean of 68.5 shoots per explant, as well as the greatest shoot height (5.1 cm). The best root induction was obtained from NAA 0.2 mg/L, producing a plant length (18.27 cm), plant height (9.60 cm), root length (8.67 cm), and plant fresh weight (1.49 g). During the acclimatization stage, the 12-day covering treatment produced the best seedlings, as evinced by plant length (25.8 cm), shoot height (19.5 cm), root length (7.9 cm), fresh weight (1.85 g), leaf width (3.0 cm), and a survival rate of 100%.

Eight rice genotypes, including Binam, Hashemi, Deylamani, TH1, Hasani, Saleh, IR75479-199-3-3, and Gohar, were crossed in a line tester mating design to generate breeding populations, assess the general and specific combining ability (GCA and SCA) and identify suitable combinations for yield. 23 genotypes (15 F1s and eight parents) were evaluated in a randomized complete block design with three replications at the Rice Research Institute of Iran during the 2020 cropping season. Analysis of variance revealed significant genotype effects and GCA and SCA mean square values for all the investigated traits, which indicated the genetic diversity of the parental genotypes and the importance of both additive and non-additive gene effects in the inheritance of the studied traits. Results indicated that additive gene action controlled plant height. Meanwhile, non-additive gene action controlled panicle length, number of panicles per plant, heading date, hundred-grain weight, number of grains per panicle, and grain yield. Effects of general combining ability were significant for the panicle length, the number of panicles per plant, heading date, hundred-grain weight, number of grains per panicle, and plant height in all testers. Hasani and Saleh's genotypes demonstrated to be good general combiners for early maturity. Gohar was the best specific combiner to enhance yield components. Hashemi×Gohar was identified as the best combination for improving grain yield and reducing the number of days to heading. The predominance of non-additive types of gene actions related to grain yield and its components suggested that selecting the best plants should be postponed to advanced generation.

Mungbean is one of the prominent pulse crops in Indonesia since the mungbean seeds are highly nutritious and has become an important part of the diet for the community. The black-seeded mungbean highly nutritious as it contains high anthocyanin content. We have developed a black-seeded mungbean lines that need to be evaluated for drought tolerance. Drought tolerance is important as mungbean is usually cultivated during the drought-prone dry season that leads to total loss. This study aimed to (1) determine the effectiveness of drought tolerance indices to select drought tolerance in black-seeded mungbean, (2) reveal the drought indices most suitable to select drought-tolerant, high- yielding black-seeded mungbean lines. This study was conducted during dry season in the Field Laboratory of Universitas Nusa Cendana. A Split-Plot design was employed, consisting of irrigation frequencies as the main plot and mungbean genotype as the sub- plot treatments. The main plot consisted of three levels, i.e. irrigation every day (I1), every four days (I2), and every seven days (I3), and the subplot consisted of 23 mungbean genotypes. Seed yields under non-stress and stress conditions were used to calculate the drought indices. The data were subjected to ANOVA, PCA and correlation analysis. There were significant variations in seed yields among genotypes under different drought indices. The indices MP, GMP, STI, HARM, MRP, SSI, YSI, MSTIK1, and MSTIK2 are suitable for selection of drought-tolerant, high-yielding mungbean lines. V9.HT, V10.HT, V11.HT, V16.HT, V18.HT, V19.HT, V20.HT, V22.HT were potential for further evaluation as promising drought tolerant, high yielding varieties.

CRISPR (clustered regularly interspaced short palindromic repeats) gene-edited (GEd) crops have demonstrated significant potential to enhance global food security in the face of escalating climate challenges and rapid population growth. Since 2019, for regulatory purposes, the United States (U.S.) and several other countries have recognized transgene-free, genome-edited lines as equivalent to conventionally bred varieties. Notably, the first genome-edited food product, Calyno™ soybean oil, was commercialized in the U.S. and marketed as a non-genetically modified organism (GMO) item. Recently, regulatory frameworks, such as the enactment of the Precision Breeding Law in the United Kingdom, the European Union’s New Genomic Techniques (NGT) legislation, and the repeal of the SECURE Rule in the United States, have further established guidelines permitting the use of genome-edited lines in agriculture similar to with conventionally bred crops, provided that these lines are free of transgenic elements. In Korea, researchers and policymakers are actively engaging in discussions to establish a preliminary review committee for GEd crops to align regulatory practices with international trade standards. Thus, this study aimed to evaluate two gene-edited rice lines for generational stability in terms of molecular characteristics, focusing on edited nucleotide sequences, gene expression, target phenotypes, the presence of transgene elements, and potential off-target effects across multiple generations. Additionally, several technical challenges in nucleotide editing tracing emerged during the evaluation process that warrant further attention. The findings presented in this study are expected to offer valuable insights for shaping the regulatory framework in Korea for CRISPR-based gene-edited crops.

Plant breeding relies on genetic variation to produce new and improved cultivars. One way to obtain novel traits is by inducing mutations. The present study aimed to create a Fusarium crown rot (FCR) and Fusarium head blight (FHB)-resistant mutagenized wheat population using ethyl methane sulphonate (EMS) and identify mutant resistance to FCR and FHB, which could provide a starting point for resistance breeding. The optimal mutagenesis conditions were determined based on the germination percentage. This study used six Chinese wheat cultivars, namely Jimai22, Hengguan35, Shixin828, Gaoyou2018, Keiwei20, and Keiwei18, to create a mutant population by treating them with EMS. For Shixin828, the optimal condition was 0.8% EMS with a 50-55% germination rate. For Hengguan35 and Jimai22, it was 0.6% EMS. For Gaoyou2018 and Kewei20, it was 0.8% and 0.4-0.6%, respectively. The FCR disease index of the mutant lines (M1) ranged from 10.00 to 77.67. For M2, the number of individual mutant plants demonstrating resistance to FCR varied from 76 to 102. In M3, 570 healthy plants were obtained using various EMS concentrations. The mutant line Kewei18 demonstrated the most resistance to FCR, FHB, and Deoxynivalenol (DON) infection. Kewei20 mutants had a higher FHB susceptibility than other mutants. Overall, mutants from the Kewei18 genetic background displayed better disease resistance to both diseases and DON contamination than natural plants. Mutants with or moderate resistance to FCR and FHB could be used in breeding and genetic studies to identify FHB and FCR-resistant Quantitative Trait Locus (QTL) in wheat.
