Brassinosteroid-Insensitive Dwarf Mutants of Arabidopsis Accumulate Brassinosteroids [PDF]

Plant Physiology, 1999
Abstract Seven dwarf mutants resembling brassinosteroid (BR)-biosynthetic dwarfs were isolated that did not respond significantly to the application of exogenous BRs. Genetic and molecular analyses revealed that these were novel alleles ofBRI1 (Brassinosteroid-Insensitive 1), which encodes a receptor kinase that may act as a receptor ...

Reactive oxygen species, antioxidants and the regulation of plant development

The FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

Biosynthetic Pathways of Hormones in Plants

Metabolites, 2023
Phytohormones exhibit a wide range of chemical structures, though they primarily originate from three key metabolic precursors: amino acids, isoprenoids, and lipids.

TaHDA1‐mediated histone and non‐histone deacetylation orchestrates drought tolerance in wheat

Journal of Integrative Plant Biology, EarlyView.
The histone deacetylase TaHDA1 is a key regulator linking histone and non‐histone deacetylation with drought adaptation and a potential target for improving drought resilience and grain nutritional quality in wheat. ABSTRACT Drought stress severely constrains wheat (Triticum aestivum L.) growth and productivity.

An OsSK12/13‐OsERF60‐OsHsfA2c module regulates heat stress tolerance in rice

Journal of Integrative Plant Biology, EarlyView.
The heat‐induced GSK3‐like kinases OsSK12 and OsSK13 phosphorylate and stabilize the transcription factor OsERF60, which activates the expression of downstream genes including the heat shock factor gene OsHsfA2c. This regulatory module governs heat‐responsive gene induction, representing a mechanistic target for enhancing crop resilience under climate ...

BRASSINOSTEROIDS PREVENT THE CYTOKININ-INDUCED SOMATIC EMBRYOGENESIS OF COFFEEBRASSINOSTEROIDS PREVENT THE CYTOKININ-INDUCED SOMATIC EMBRYOGENESIS OF COFFEE (Coffea canephora)

Acta Biológica Colombiana
Plant somatic embryogenesis is a natural process that can be replicated in vitro by adding plant growth regulators. Reports in dicate that the application of brassinosteroids increased the number of embryos when added to the cytokinin-induced somatic ...

Jasmonate biosynthesis regulates key events in barley vegetative and reproductive development

New Phytologist, EarlyView.
Generation and general phenotypes of hvaoc mutants. Summary Cereal grain is a global food staple. Filial tissues in grain, such as the embryo and endosperm, grow embedded in the maternal ovule and surrounding ovary wall. Maternal tissues provide nutrition and protection but are progressively reduced and degraded as filial tissues expand, driving grain ...

MYB156 promotes root sucker formation by repressing IDD14 and CKX1 to elevate cytokinin levels in Populus

New Phytologist, EarlyView.
Schematic model illustrating MYB156‐mediated regulatory network controlling root‐sucker formation. Summary Root suckers enable clonal propagation of rooting‐recalcitrant poplars, conferring rejuvenated traits such as enhanced survival and accelerated growth.

Overexpression of SoCYP85A1, a Spinach Cytochrome p450 Gene in Transgenic Tobacco Enhances Root Development and Drought Stress Tolerance

Frontiers in Plant Science, 2017
Brassinosteroids (BRs) play an essential role in plant growth, development, and responses to diverse abiotic stresses. However, previous studies mainly analyzed how exogenous BRs influenced plant physiological reactions to drought stress, therefore ...

Photosynthesis Mediated by RBOH-Dependent Signaling Is Essential for Cold Stress Memory

Antioxidants, 2022
Cold tolerance is improved by cold stress acclimation (CS-ACC), and the cold tolerance level is ‘remembered’ by plants. However, the underlying signaling mechanisms remain largely unknown.
