PEDUNCLE LENGTH 1 regulates wheat peduncle elongation through brassinosteroid signaling pathway.

This study identifies TaPL1, a MADS-box transcription factor underlying the QFiriti-6B QTL, as a key regulator of peduncle elongation in wheat. TaPL1 enhances brassinosteroid signaling through direct suppression of TaBKI1, and its loss-of-function alleles exhibit reduced plant height and peduncle length, but increased grain weight, offering valuable targets for yield improvement in wheat breeding.

Comparative Analysis of miRNA Expression Profiles under Salt Stress in Wheat.

Salt stress is one of the important environmental factors that inhibit the normal growth and development of plants. Plants have evolved various mechanisms, including signal transduction regulation, physiological regulation, and gene transcription regulation, to adapt to environmental stress. MicroRNAs (miRNAs) play a role in regulating mRNA expression.

Increasingly amplified stimulation mediated by TaNAC69-B is crucial for the leaf senescence in wheat.

Leaf senescence involves massive multidimensional alterations, such as nutrient redistribution, and is closely related to crop yield and quality. No apical meristem, Arabidopsis transcription activation factor, and Cup-shaped cotyledon (NAC)-type transcription factors integrate various signals and modulate an enormous number of target genes to ensure the appropriate progression of leaf senescence. However, few leaf senescence-related NACs have been functionally characterized in wheat.

TaWRKY13-A Serves as a Mediator of Jasmonic Acid-Related Leaf Senescence by Modulating Jasmonic Acid Biosynthesis.

Leaf senescence is crucial for crop yield and quality. Transcriptional regulation is a key step for integrating various senescence-related signals into the nucleus. However, few regulators of senescence implicating transcriptional events have been functionally characterized in wheat.
