An Antagonism Between Ethylene Signaling and DNA Methylation Orchestrates the Progression of Leaf Senescence in Non‐heading Chinese Cabbage

open access: yesAdvanced Science, EarlyView.
CMT2 mediates the maintenance of DNA methylation on the promoters of SAGs, thereby inhibiting EIN3A untimely activating SAGs’ expression. Aging‐impelled striking upregulation of EIN3A strongly suppresses the expression of CMT2 to reduce the methylation level, which releases the activation of EIN3A on SAGs, thus initiating and accelerating the ...

Abscisic Acid Biosynthesis and Response [PDF]

open access: yesThe Arabidopsis Book, 2002
Abscisic acid (ABA) is an optically active 15-C weak acid that was first identified in the early 1960s as a growth inhibitor accumulating in abscising cotton fruit (“abscisin II”) and leaves of sycamore trees photoperiodically induced to become dormant (“dormin”) (reviewed in Addicott, 1983).

Genomic and Cis‐Regulatory Basis of a Plastic C3‐C4 Photosynthesis in Eleocharis Baldwinii

open access: yesAdvanced Science, EarlyView.
The sedge Eleocharis baldwinii remarkably switches between C3‐like and C4‐like photosynthesis in response to environmental conditions. Combining gap‐free genome assembly with single‐cell multi‐omics, this study uncovers how subgenome dominance and cell‐specific cis‐regulation enable C4 photosynthesis.

A Mass Spectrometry Approach Reveals Fatty Acid Isomerism in Tomato Cold Tolerance

open access: yesAdvanced Science, EarlyView.
An enhanced mass spectrometry approach reveals fatty acids (FAs) and FA isomers that are critical for tomato cold tolerance. Applying specific FA isomers can partially rescue cold sensitivity in tomato mutant plants, highlighting the importance of FA isomers in plant cold stress adaptation.

De Novo Regulatory Motif Discovery Identifies Significant Motifs in Promoters of Five Classes of Plant Dehydrin Genes. [PDF]

open access: yesPLoS ONE, 2015
Plants accumulate dehydrins in response to osmotic stresses. Dehydrins are divided into five different classes, which are thought to be regulated in different manners.

TaPPR13, a Pentatricopeptide Repeat Protein Gene Activated by TaBZR2, Confers Drought Stress Tolerance by Enhancing the Antioxidant Defense System and Promoting Retrograde Signaling in Wheat (Triticum aestivum)

open access: yesAdvanced Science, EarlyView.
TaPPR13, a PPR protein family gene in wheat is activated by TaBZR2 to enhance drought stress tolerance and photosynthetic capacity. It achieves this by interacting with TaAOR1 and TaSIG5 to improve antioxidant defense and regulate chloroplast gene expression. Abstract The wheat (Triticum aestivum) brassinazole‐resistant 2 (TaBZR2) gene is identified as

Cytological and molecular characteristics of delayed spike development in wheat under low temperature in early spring

open access: yesCrop Journal, 2022
Low temperature in early spring impairs wheat growth and grain yield. However, little is known about the cytological and molecular mechanisms underlying low temperature regulation of wheat spike development.
