Опубликована: Июль 25, 2023

Phytohormones exhibit a wide range of chemical structures, though they primarily originate from three key metabolic precursors: amino acids, isoprenoids, and lipids. Specific such as tryptophan, methionine, phenylalanine, arginine, contribute to the production various phytohormones, including auxins, melatonin, ethylene, salicylic acid, polyamines. Isoprenoids are foundation five phytohormone categories: cytokinins, brassinosteroids, gibberellins, abscisic strigolactones. Furthermore, lipids, i.e., α-linolenic function precursor for jasmonic acid. The biosynthesis routes these different plant hormones intricately complex. Understanding processes can greatly enhance our knowledge how regulate growth, development, physiology. This review focuses on detailing biosynthetic pathways phytohormones.

The transcription factor MYB110 regulates plant height, lodging resistance, and grain yield in rice

The Plant Cell, Год журнала: 2023, Номер 36(2), С. 298 - 323

Abstract The high-yielding Green Revolution varieties of cereal crops are characterized by a semidwarf architecture and lodging resistance. Plant height is tightly regulated the availability phosphate (Pi), yet underlying mechanism remains obscure. Here, we report that rice (Oryza sativa) R2R3-type Myeloblastosis (MYB) transcription factor MYB110 Pi-dependent negative regulator plant height. direct target PHOSPHATE STARVATION RESPONSE 2 (OsPHR2) regulates OsPHR2-mediated inhibition Inactivation increased culm diameter bending resistance, leading to enhanced resistance despite Strikingly, grain yield myb110 mutants was elevated under both high- low-Pi regimes. Two divergent haplotypes based on single nucleotide polymorphisms in putative promoter corresponded with its transcript levels response Pi availability. Thus, fine-tuning expression may be potent strategy for further increasing crop varieties.

OsWRKY78 regulates panicle exsertion via gibberellin signaling pathway in rice

Journal of Integrative Plant Biology, Год журнала: 2024, Номер 66(4), С. 771 - 786

Опубликована: Март 12, 2024

ABSTRACT Panicle exsertion is one of the crucial agronomic traits in rice ( Oryza sativa ). Shortening panicle often leads to enclosure and severely reduces seed production. Gibberellin (GA) plays important roles regulating exsertion. However, underlying mechanism relative regulatory network remain elusive. Here, we characterized oswrky78 mutant showing severe enclosure, found that defect caused by decreased bioactive GA contents. Biochemical analysis demonstrates OsWRKY78 can directly activate biosynthesis indirectly suppress metabolism. Moreover, interact with be phosphorylated mitogen‐activated protein kinase (MAPK) OsMAPK6, this phosphorylation enhance stability necessary for its biological function. Taken together, these results not only reveal critical function OsWRKY78, but also via mediating crosstalk between MAPK signaling pathway

Space-induced plant mutagenesis, driven by cosmic radiation, offers a promising approach for the selective breeding of new varieties. By leveraging unique environment outer space, we successfully induced mutagenesis in 'Deqin' alfalfa and obtained fast-growing mutant. However, molecular mechanisms underlying its rapid growth remain poorly unexplored. Comparative analyses transcriptomics, proteomics, hormone profiles were conducted root, stem, leaf tissues both mutant non-mutagenic materials. Targeted showed notable increases levels 3-indolebutyric, indole-3-acetic, 3-indolepropionic acids mutant, with percentage 33.55%, 32.49%, 30.39%, respectively. Zeatin-riboside dihydrozeatin riboside increased 164.92% 25.86%, while giberellin (GA) 7, GA3, GA1 219.52%, 68.74%, 40.98%. Non-mutagenic materials sprayed exogenous 3-indolebutyric acid, zeatin-riboside, GA7 exhibited significant acceleration.

Plant height (PH) in rice (Oryza sativa) is an important trait for its adaptation and agricultural performance. Discovery of the semi-dwarf1 (SD1) mutation initiated Green Revolution, boosting yield fitness, but underlying genetic regulation PH remains largely unknown. Here, we performed genome-wide association study (GWAS) identified 12 non-repetitive QTL/genes regulating variation 619 Asian cultivated accessions. One these was SD1 structural variant, not normally detected standard GWAS analyses. Given strong effect on PH, also divided accessions into subgroups harbouring distinct haplotypes, found a further 85 revealing heterogeneity that may be missed by analysing broad, diverse population. Moreover, uncovered two epistatic interaction networks PH-associated japonica (Geng)-dominant SD1NIP subgroup. In one them, hub QTL/gene qphSN1.4/GAMYB interacted with qphSN3.1/OsINO80, qphSN3.4/HD16/EL1, qphSN6.2/LOC_Os06g11130, qphSN10.2/MADS56. Sequence variations GAMYB MADS56 were associated their expression levels variations, shown to physically interact MADS57 coregulate gibberellin (GA) metabolic genes OsGA2ox3 Elongated Uppermost Internode1 (EUI1).

Plant height is an important agronomic trait that closely associated with crop yield and quality. Gibberellins (GAs), a class of highly efficient plant growth regulators, play key roles in regulating height. Increasing reports indicate transcriptional regulation major point the GA pathways. Although substantial knowledge has been gained regarding biosynthetic signaling pathways, factors contributing to regulatory mechanisms homeostatically controlling levels remain be elucidated. Here, we provide overview current network involving transcription factors, noncoding RNAs, histone modifications involved We also discuss interaction between GAs other hormones development. Finally, future directions for applying hormone breeding are described.
