It is often stated that agricultural outputs need to increase substantially meet the demands for more food posed by a growing population. However, when accounting climate change, we argue current projected increases are unrealistic and realistic goal would be maintain yields per area of production. This will require breeding crops with increased tolerance abiotic stresses such as drought, salinity, waterlogging, high temperatures. can accomplished in one two ways: introducing stress genes into present high-yielding or increasing already tolerant orphan and/or wild plants. We first strategy easing restrictions on use gene editing technologies making substantial improvements cell-based phenotyping identify available pool crop its relatives. The success second depend number domestication selected order obtain comparable present-day cultivars. still too early conclude which strategies, rewilding (bringing lost from ancestors back domesticated crops) de novo (domesticating resilient plants underutilized directly), most effective future sustainable agriculture. given importance issue, some rapid action needs taken.

Salt tolerance is a critical trait for plant survival and productivity in saline environments. Development of salt tolerant crops practical strategy addressing soil salinity issues. In this study, RNA-Seq analysis was performed using two wheat cultivars with contrasting (Neixiang188, Barra, sensitive) at 6 h 24 after treatment to determine the genetic variations reflected RNA expression patterns identify key genes associated tolerance. Our results revealed that there were 2983 upregulated 1091 downregulated differentially expressed (DEGs), which found common accessions. Meanwhile, 529 DEGs subjected GO function annotation, KEGG enrichment, protein–protein interaction (PPI) network prediction. Finally, theoretical framework outlining mechanisms Neixiang188 proposed. It can be inferred possesses superior ion homeostasis, ROS detoxification, osmotic adjustment abilities compared Barra when stress. The present research sheds light on foundation offers candidate manipulation. insights enhance comprehension molecular underlying stress responses could guide future breeding efforts improving crops.

Abstract Yellow rust (YR), caused by Puccinia striiformis f. sp. tritici (Pst), poses a significant threat to wheat production worldwide. Breeding resistant cultivar is crucial for managing this disease. However, understanding of the genetic mechanisms underlying YR resistance remains fragmented. To address this, we conducted comprehensive analysis with variome data from 2,191 accessions worldwide and over 47,000 response records across multiple environments pathogen races. Through genome-wide association studies, established landscape 431 loci, providing rich resource (R) gene deployment. Furthermore, cloned genes corresponding three namely Yr5x effective against Pst races, Yr6/Pm5 that conferred two species, YrKB (TaEDR2-B) conferring broad-spectrum without yield penalty. These findings offer valuable insights into basis in lay foundation engineering durable disease resistance.

Summary FLOWERING LOCUS T ( FT ), a multifunctional regulator in crops, modulates multiple key agronomic traits such as flowering time or heading date and plant height; however, its role grain development regulation is unclear. Herein, through genome‐wide association studies (GWAS), we identified TaFT‐D1 , which encodes phosphatidylethanolamine‐binding protein (PEBP), candidate gene for weight wheat. A one‐bp insertion/deletion (InDel) (G/‐) the third exon of resulting different lengths, was significantly associated with weight. knockout via CRISPR‐Cas9 system reduced size weight, increased by promoting cell proliferation starch synthesis. Transcriptome analysis revealed significant decrease expression cycle‐ synthesis‐related genes, including TaNAC019‐3A TaSWEET15‐like‐7B TaCYCD4;1 TaCYCD3;2 taft‐d1 line. interacted bZIP transcription factor TaFDL2, tafdl2 mutant presented relatively small grains, suggesting that TaFDL2 positive size. Moreover, bound to promoters downstream activating their expression, whereas this activation TaFDL2. Interaction assays demonstrated TaFT‐D1, Ta14‐3‐3A formed regulatory complex. Furthermore, TaFT‐D1(G) allele correlated greater thousand‐grain earlier heading. This favourable has undergone strong selection during wheat breeding China.

Summary Hybrid potato breeding offers a promising solution to tackle the challenges in breeding. However, most diploids are self‐incompatible (SI), which hinders development of inbred lines. S‐locus inhibitor ( Sli ) is ‘master key’ gene capable conferring self‐compatibility (SC) SI diploids, yet regulatory mechanism underlying its male gamete‐specific expression remains unclear, limiting potential. This study has uncovered that miniature inverted‐repeat transposable element (Mi‐549) within promoter can affect methylation pattern promoter, thereby regulating pollen‐specific as well SC phenotype diploids. We delved into origin Mi‐549 Petota and found was likely acquired fortuitously wild Solanum lesteri but not favored during domestication, probably due asexual propagation nature potato. Although impacts on selected, screening identified three novel accessions belong S. , neocardenasii stenotomum enrich germplasm pool associated with stress pest resistance hold significant value for applications.
