The coastal regions of Bangladesh host a rich diversity Aman rice landraces, which are crucial for local agriculture but highly vulnerable to natural disasters like cyclones and floods. Specifically, landraces often experience flooding during grain filling maturation stages, sprouts in the field lead severe loss yield. Seed dormancy, delays germination, is key trait escaping sprouting harvesting. However, there lack information on genetic variability existing grown area Bangladesh. This study evaluated seed dormancy 28 plus four varieties from Institute Nuclear Agriculture Rice Research Institute. Germination tests were conducted under controlled conditions, an electrical conductivity (EC) test was used assess vigor. results showed that Bari Mota, Tulsimala, Chinigura, Dishari, Birindi exhibited highest rates, i.e., 100%, 99%, respectively, while BINA Dhan 10, Nona Bokra, 8 had lowest with values 11%, 16%, 24%, respectively. Priming treatments enhanced germination rates some varieties; however, others, such as Mota remained dormant, underscoring levels. Compared non-priming, significant improvement recorded BRRI dhan 41 (85.3% vs. 9%), Motha mota (84% 8%), Lal chikon (74.6% 1%), Sadamota 5%), Bashful (53.3% 3%). Altogether, our suggest diverse genotypes high can potentially be disaster-prone areas. In contrast, these future breeding programs. Therefore, this carries implications cultivation areas

As the intensity and frequency of extreme weather events are projected to increase under climate change, assessing their impact on cropping systems exploring feasible adaptation options is increasingly critical. Process-based crop models (PBCMs), which widely used in change assessments, have improved simulating impacts major such as heatwaves droughts but still fail reproduce low yields wet conditions. Here, we provide an overview yield-loss mechanisms excessive rainfall cereals (i.e., waterlogging, submergence, lodging, pests diseases) associated modelling approaches with aim guiding PBCM improvements. Some PBCMs simulate waterlogging ponding environments, few capture aeration stresses growth. Lodging often neglected by PBCMs; however, some stand-alone mechanistic lodging exist, can potentially be incorporated into PBCMs. frameworks link process-based epidemic consideration different damage mechanisms. However, lack data calibrate evaluate these model functions limit use frameworks. In order generate for improvement close knowledge gaps, targeted experiments diseases required. all may result excessively complex a large number parameters, increasing uncertainty. Modular could assist selecting necessary lead appropriate structures complexity that fit specific research question. Lastly, there potential synergies between PBCMs, statistical models, remotely sensed improve prediction accuracy understanding current PBCMs' shortcomings.

The green revolution was based on genetic modification of the gibberellin (GA) hormone system with "dwarfing" gene mutations that reduces GA signals, conferring shorter stature, thus enabling plant adaptation to modern farming conditions. Strong GA-related mutants stature often have reduced coleoptile length, discounting yield gain due their unsatisfactory seedling emergence under drought Here we present 3-oxidase1 (GA3ox1) as an alternative semi-dwarfing in barley combines optimal reduction height without restricting and growth. Using large-scale field trials extensive collection accessions, showed a natural GA3ox1 haplotype moderately by 5-10 cm. We used CRISPR/Cas9 technology, generated several novel validated function GA3ox1. altered activities changed level active isoforms consequently increased length average 8.2 mm, which could provide essential maintain climate change. revealed CRISPR/Cas9-induced seed dormancy ideal benefit malting industry. conclude selecting HvGA3ox1 alleles offers new opportunity for developing varieties longer additional agronomic traits.

The economic and health significance of quinoa is steadily growing on a global scale. Nevertheless, the primary obstacle to achieving high yields in cultivation pre-harvest sprouting (PHS), which intricately linked seed dormancy. However, there exists dearth research concerning regulatory mechanisms governing PHS. regulation germination by various plant hormones has been extensively studied. Consequently, understanding underlying role endogenous process seeds developing strategies mitigate PHS are significant importance. This study employed HPLC-ESI-MS/MS internal standard ELISA method quantify 8 hormones. investigation gene expression changes before after was conducted using RNA-seq analysis, leading discovery 280 differentially expressed genes associated with pathway Additionally, correlation analysis 99 differences identified 14 potential that may act as crucial "transportation hubs" hormonal interactions.

To survive in the dry state, orthodox seeds acquire desiccation tolerance. As maturation progresses, gradually longevity, which is total timespan during remain viable. The desiccation-tolerance mechanism(s) allow to without losing their ability germinate. This adaptive trait has played a key role evolution of land plants. Understanding mechanisms for seed survival after one central goals still unsolved. That is, cellular protection state and cell repair rewatering involves not entirely known molecular network(s). Although tolerance retained higher plants, resurrection plants belonging different plant lineages keep vegetative tissue. Abscisic acid (ABA) involved through tight control synthesis unstructured late embryogenesis abundant (LEA) proteins, heat shock thermostable proteins (sHSPs), non-reducing oligosaccharides. During maturation, progressive loss water induces formation so-called "glass state". glassy matrix consists soluble sugars, immobilize macromolecules offering membranes proteins.

Wheat (Triticum aestivum L.) is an important cereal crop. Increasing grain yield for wheat always a priority. Due to the complex genome of hexaploid with 21 chromosomes, it difficult identify underlying genes by traditional genetic approach. The combination genetics and omics analysis has displayed powerful capability candidate major quantitative trait loci (QTLs), but such studies have rarely been carried out in wheat. In this study, related were predicted combined use linkage mapping weighted gene co-expression network (WGCNA) recombinant inbred line population.QTL was performed plant height (PH), spike length (SL) seed traits. A total 68 QTLs identified them, among which, 12 stably across different environments. Using RNA sequencing, we scanned 99,168 expression patterns whole population.
