The miR3367–lncRNA67–GhCYP724B module regulates male sterility by modulating brassinosteroid biosynthesis and interacting with Aorf27 in Gossypium hirsutum

Journal of Integrative Plant Biology, Volume 67, Issue 1, Page 169-190, January 2025.
In the fertile cotton (Gossypium hirsutum) line 2074B, the long non‐coding RNA lncRNA67 acted as an endogenous target mimic, regulating microRNA‐mediated cleavage of GhCYP724B, encoding a cytochrome P450 that promotes brassinosteroid biosynthesis. In the cytoplasmic male sterile line 2074A, GhCYP724B interacted with a unique chimeric open reading frame,

GhCASPL1 regulates secondary cell wall thickening in cotton fibers by stabilizing the cellulose synthase complex on the plasma membrane

Journal of Integrative Plant Biology, Volume 66, Issue 12, Page 2632-2647, December 2024.
The cellulose synthase complex–interacting factor CASPARIAN STRIP MEMBRANE DOMAIN‐LIKE1 plays a crucial role in regulating secondary cell wall thickening in cotton fibers by stabilizing the cellulose synthase complex on the plasma membrane. ABSTRACT Cotton (Gossypium hirsutum) fibers are elongated single cells that rapidly accumulate cellulose during ...

Morphology of flower bud differentiation and floral organ specialization in Caucasian clover

Grass and Forage Science, Volume 79, Issue 3, Page 381-391, September 2024.
Abstract Flower bud differentiation is the commencement of plant reproductive development. Flower organ specialization follows flower bud differentiation. This biological mechanism controls whether plants reproduce successfully via seed. Caucasian clover (Trifolium ambiguum) is used in mixed temperate pastures.

OsALKBH9‐mediated m6A demethylation regulates tapetal PCD and pollen exine accumulation in rice

Plant Biotechnology Journal, Volume 22, Issue 9, Page 2410-2423, September 2024.
Summary The N6‐methyladenosine (m6A) mRNA modification is crucial for plant development and stress responses. In rice, the male sterility resulting from the deficiency of OsFIP37, a core component of m6A methyltransferase complex, emphasizes the significant role of m6A in male fertility. m6A is reversible and can be removed by m6A demethylases. However,

A promoter polymorphism defines distinct roles in anther development for Col‐0 and Ler‐0 alleles of Arabidopsis ACYL‐COA BINDING PROTEIN3

New Phytologist, Volume 243, Issue 4, Page 1424-1439, August 2024.
Summary Acyl‐CoA‐Binding Proteins (ACBPs) bind acyl‐CoA esters and function in lipid metabolism. Although acbp3‐1, the ACBP3 mutant in Arabidopsis thaliana ecotype Col‐0, displays normal floral development, the acbp3‐2 mutant from ecotype Ler‐0 characterized herein exhibits defective adaxial anther lobes and improper sporocyte formation.

Elucidating the mechanism of poricidal anther dehiscence on Miconia species (Melastomataceae)

, 2015
Melastomataceae have porate anthers. However, unlike Solanaceae and many monocots, in which the poricidal dehiscence depends on the presence of a mechanical layer (often the endothecium), most members of Melastomataceae have no evident specialized layer ...
