The Birth and Death of Floral Organs in Cereal Crops

Annual Review of Plant Biology, Год журнала: 2024, Номер 75(1), С. 427 - 458

Florets of cereal crops are the basic reproductive organs that produce grains for food or feed. The birth a floret progresses through meristem initiation and floral organ identity specification maintenance. During these processes, both endogenous external cues can trigger premature death, leading to failure. Recent advances in different have identified conserved distinct regulators governing floret. However, molecular underpinnings death just beginning be understood. In this review, we first provide general overview current findings field development major cereals outline forms deaths, particularly Triticeae crops. We then highlight importance vascular patterning photosynthesis success argue an expanded knowledge birth–death balance context agroecology.

TaFT‐D1 positively regulates grain weight by acting as a coactivator of TaFDL2 in wheat

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. Our findings provide novel insights into how regulates highlight potential application yield improvement
