Flg22-Triggered Immunity Negatively Regulates Key BR Biosynthetic Genes [PDF]
, 2015 In plants, activation of growth and activation of immunity are opposing processes that define a trade-off. In the past few years, the growth-promoting hormones brassinosteroids (BR) have emerged as negative regulators of pathogen-associated molecular ...

Local auxin biosynthesis acts downstream of brassinosteroids to trigger root foraging for nitrogen
Nature Communications, 2021 Lateral roots (LRs) dominate the overall root surface of adult plants and are crucial for soil exploration and nutrient acquisition. When grown under mild nitrogen (N) deficiency, flowering plants develop longer LRs to enhance nutrient acquisition.

Brassinosteroid transport [PDF]
Journal of Experimental Botany, 2007 Brassinosteroids (BRs) are steroidal plant hormones that are important regulators of plant growth. These compounds are widely distributed throughout reproductive and vegetative plant tissues. This raises the question of whether or not BRs are transported over long distances between these tissues.

Brassinosteroids in Plants: Crosstalk with Small-Molecule Compounds
Biomolecules, 2021 Brassinosteroids (BRs) are known as the sixth type of plant hormone participating in various physiological and biochemical activities and play an irreplaceable role in plants.

Brassinosteroid signalling [PDF]
Development, 2013 The brassinosteroid (BR) class of steroid hormones regulates plant development and physiology. The BR signal is transduced by a receptor kinase-mediated signal transduction pathway, which is distinct from animal steroid signalling systems. Recent studies have fully connected the BR signal transduction chain and have identified thousands of BR target ...

BZR1 Regulates Brassinosteroid-Mediated Activation of AMT1;2 in Rice
Frontiers in Plant Science, 2021 Although it is known that brassinosteroids (BRs) play pleiotropic roles in plant growth and development, their roles in plant nutrient uptake remain unknown. Here, we hypothesized that BRs directly regulate ammonium uptake by activating the expression of

Roles of Brassinosteroids in Plant Reproduction
International Journal of Molecular Sciences, 2020 Brassinosteroids (BRs) are a group of steroid hormones, essentially important for plant development and growth. BR signaling functions to promote cell expansion and cell division, and plays a role in etiolation and reproduction.

Systemic suppression of the shoot metabolism upon rice root nematode infection [PDF]
, 2014 Hirschmanniella oryzae is the most common plant-parasitic nematode in flooded rice cultivation systems. These migratory animals penetrate the plant roots and feed on the root cells, creating large cavities, extensive root necrosis and rotting.

Emerging connections between small RNAs and phytohormones [PDF]
, 2020 Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.

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 for
