The structure, biosynthesis and function of brassinosteroids

1、The structure, biosynthesis and function of brassinosteroids

It appears that brassinosteroids promote cell elongation, thereby influencing the growth of plants, and that the control of brassinosteroid levels is an essential requirement for normal plant growth.

2、Structural insights into a key step of brassinosteroid biosynthesis and

Brassinosteroids (BRs) are essential plant steroid hormones that regulate plant growth and development 1. The most potent BR, brassinolide, is produced by addition of many oxygen atoms to...

3、Biosynthesis and metabolism of brassinosteroids

Detailed study of the biosynthesis of brassinolide, a C28 BR, revealed that two parallel routes, the early and late C-6 oxidation pathways, are connected at multiple steps and also are linked to the early C-22 oxidation pathway. Thus, BR biosynthetic pathways are highly networked.

Frontiers

Brassinosteroids (BRs) as a class of steroid plant hormones participate in the regulation of numerous developmental processes, including root and shoot growth, vascular differentiation, fertility, flowering, and seed germination, as well as in responding to environmental stresses.

Biosynthesis and Molecular Mechanism of Brassinosteroids Action

Biosynthesis and signal transduction have been well analyzed through forward and reverse genetics. In the biosynthesis pathways, BRs can be synthesized by a pathway dependent on cycloartenol or cycloartanol. A receptor kinase-mediated signal transduction pathway transduces the BR signal.

Brassinosteroid biosynthesis and signaling: Conserved and diversified

In this manuscript, we comprehensively review functional studies of BR genes in Arabidopsis, maize, rice, Setaria, Brachypodium, and soybean to identify conserved and diversified functions across plant species and to highlight cases for which additional research is in order.

Structural insights into a key step of brassinosteroid biosynthesis and

Here we show the crystal structure of Arabidopsis thaliana CYP90B1 complexed with cholesterol as a substrate. The substrate-binding conformation explains the stereoselective introduction of a hydroxy group at the 22S position, facilitating hydrogen bonding of brassinolide with the BR receptor 3-5.

Comprehensive Overview of the Brassinosteroid Biosynthesis Pathways

Brassinosteroids (BRs) as a class of steroid plant hormones participate in the regulation of numerous developmental processes, including root and shoot growth, vascular differentiation, fertility, flowering, and seed germination, as well as in responding to environmental stresses.

Brassinosteroids

Brassinosteroids (BR's) represent highly active plant-growth-promoting substances with structures similar to animal steroidal hormones.
