Rice breeding was conducted for a long time during historical times and is an important job in Vietnam because rice the major food domestic consumption export. In this review, we have provided comprehensive insight into importance of promising germplasm resources, achievements, approaches as well discussed challenges perspectives country. With wild relative resources with rich various genetic diversity, their useful genes traits been exploited integrated commercial varieties final outputs programs. New achievements modern genetics era approached effectively contributed to activities Genome sequences, molecular breeding, mutation are powerful tools playing vital roles developing new characteristics interest that should be followed by current market demands. last decades, there has plethora newly generated Vietnamese scientists breeders approved state authorities. However, very few mega prevailed over imported varieties. Therefore, country faced big challenges, including limitations backgrounds, budgets, even talents basic research compete other rice-producing countries. The target goals long-term paid explicitly priority ensure national security advantage development

After a basic description of the different sets genetic tools and genomic approaches most relevant for modern crop breeding (e. g., QTL mapping, GWAS selection; transcriptomics, qPCR RNA-seq; transgenesis gene editing), this review paper describes their history main achievements in rice, wheat maize research, with further focus on traits related to improvement plant responses face major abiotic constrains, including nutritional limitations, drought heat tolerance, nitrogen-use efficiency (NUE). Remarkable differences have been evidenced regarding timing degree development some among these crops. The underlying reasons distinct genome complexity, are also considered. Based bibliographic records, tolerance topics (i.e., water-use efficiency) by far abundantly addressed molecular objectives Heat is usually more than NUE rice wheat, while opposite true maize.

Microplastics (MPs), found in many places around the world, are thought to be more detrimental than other forms of plastics. At present, physical, chemical, and biological methods being used break down MPs. Compared with physical chemical methods, biodegradation have been extensively studied by scholars because their advantages greenness sustainability. There numerous reports recent years summarizing microorganisms capable degrading However, there is a noticeable absence systematic summary on technology for breeding strains that can degrade This paper summarizes strain-breeding MP-degrading first time way, which provides new idea efficient strains. Meanwhile, potential techniques bacteria MPs proposed, providing direction selecting future. In addition, this reviews sources pollution status soil MPs, discusses current challenges related emphasizes safety MP biodegradation.

ABSTRACT Plant diseases cause significant losses to food crop production with blast being one of the most destructive affecting rice. Breeding for disease resistance is an effective approach developing varieties that can withstand such diseases, ultimately contributing stable yields in Besides hybridization, chemical mutagenesis a potential method bringing desirable genetic alteration towards seed propagated crops like Therefore, study was conducted generate variants employing ethyl methane sulfonate (EMS) mutagenesis, evaluate resulting mutants variability and identify genotypes resistant rice following completely randomized design (CRD). Seeds BRRI dhan28 were mutagenized LD50 (0.108 M) EMS develop 100 mutants. The demonstrated notable variation all traits assessed. higher level phenotypic genotypic coefficient assessed together high heritability as well advance percent mean filled grains panicle −1 , tillers hill grain straw yield harvest index. height, length, branches showed statistically positive correlation yield. cluster analysis grouped into seven main clusters, PCA 42.96% total first two components. Screening against leaf exhibited variable responses from highly susceptible. A 9 found 35 moderately disease. Seed technique generating susceptible varieties, identified serve valuable resources further research improving

Mutagenesis breeding, combined with the application of corresponding herbicides to develop herbicide-resistant rice germplasm, provides great promise for management weeds and weedy rice. In this study, a topramezone-resistant mutant, TZR1, was developed from indica line Chuangyu 9H (CY9H) through radiation mutagenesis topramezone selection. Dose–response curves revealed that resistance index TZR1 1.94-fold compared CY9H. The mechanism not due target-site resistance. This could be reversed by specific inhibitor glutathione S-transferase (GST). activity antioxidant enzymes analyzed. SNPs Indels were detected using whole-genome resequencing; differentially expressed genes identified RNA sequencing. Then, they underwent Gene Ontology Kyoto Encyclopedia Genes Genomes enrichment analyses. Key candidate associated validated via real-time quantitative PCR assay. Five GST genes, two UDP-glycosyltransferase three ATP-binding cassette transporter as potential contributors detoxification in TZR1. Overall, these findings suggest possibly play an important role topramezone. study will provide valuable information scientific 4-hydroxyphenylpyruvate dioxygenase inhibitors paddy fields future.

Ionizing radiation (IR) is an abiotic stress factor that can be not only a means to explore plant resistance but also potent mutagen in agricultural breeding. The diverse physical parameters of different types IR result varying effects on plants, which turn leads differences the spectrum genetic variations offspring. Investigating response mechanisms crucial for enhancing and comprehending mutation generation from various mutagenic sources Nevertheless, mechanism underlying complex responses plants are yet fully comprehended. we conducted transcriptome sequencing rice seedlings exhibited relative root length approximately 69% after being exposed carbon ion beams (CIBs) X-ray respectively. results revealed induced greater number differentially expressed genes (DEGs) than CIBs, with 5681 2198 DEGs were identified Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) analyses indicated DNA replication, damage repair, phytohormone signaling, antioxidant pathways implicated seedling IR. These demonstrated patterns following Additionally, through two linear energy transfer (LET), found some common contribute seedlings, such as LOC4331062, LOC4333870. This study offers insights into molecular transcriptomic impacts seedlings. It provides new perspective further exploration irradiation-induced repair factors understanding reasons mutations created by plants.

SUMMARY We identified a mutant of hexaploid wheat ( Triticum aestivum ) with impaired responses to gravity. The mutant, named Twisted Sister1 TS1 ), had agravitropic roots that were often twisted along altered shoot phenotypes. Roots insensitive externally applied auxin, the genetics and physiology suggestive mutated AUX/IAA transcription factor gene. Hexaploid possesses over 80 genes, sequence information did not identify an obvious candidate. Bulked segregant analysis F 2 population mapped mutation chromosome 5A, subsequent mapping located 41 Mbp region. RNA‐seq TraesCS5A03G0149800 gene encoding TaAUX/IAA protein be in highly conserved domain II motif. confirmed as underlying phenotype by generating transgenic Arabidopsis thaliana . Analysis data suggested broad similarities between for role genes gravity responses, although there marked differences. Here we show sequenced genome, previous knowledge from other plant species, mapping, RNA‐seq, expression have enabled cloning key defines architecture.
