The plant peptide-containing sulfated tyrosine (PSY) family plays critical roles in plant cell proliferation and stress responses. However, the functional characterization of the PSY peptide family in wheat remains unclear. This study systematically identified a total of 29 genes at the genome-wide level, classifying them into six subgroups based on PSY-like motifs.

Article Synopsis
  • - The study identified 26 endonuclease family genes (TaENDO) in the wheat genome that are linked to stress responses and growth, distributed across various chromosomes and classified into four groups based on their structures and motifs.
  • - TaENDO23, a gene of particular interest, was found to be highly expressed in wheat leaves and grains and significantly upregulated under drought stress; its expression was affected differently by various treatments.
  • - A KASP marker was developed to explore variations in TaENDO23 among different wheat accessions, showing that a specific haplotype (TaENDO23-HapI) is associated with better grain weight and size, suggesting its selection during wheat breeding.

Article Synopsis
  • The study investigates the role of TaSINA proteins in wheat growth and grain development, especially in response to environmental stresses.
  • Research found that many TaSINA genes were more actively expressed in young wheat spikes and grains, with specific haplotypes correlating with grain-related traits.
  • The development of PCR markers confirmed haplotype variations, and experiments showed that particular transgenic lines with enhanced TaSINA101 gene expression produced heavier and larger grains compared to wild-type rice.

Increasing crop yield depends on selecting and utilizing pleiotropic genes/alleles to improve multiple yield-related traits (YRTs) during crop breeding. However, synergistic improvement of YRTs is challenging due to the trade-offs between YRTs in breeding practices. Here, the favourable haplotypes of the TaCYP78A family are identified by analysing allelic variations in 1571 wheat accessions worldwide, demonstrating the selection and utilization of pleiotropic genes to improve yield and related traits during wheat breeding.

The growth of leaves is subject to strict time regulation. Several genes influencing leaf growth have been identified, but little is known about how genes regulate the orderly initiation and growth of leaves. Here, we demonstrate that contributes to a time regulation mechanism in leaves from initiation to expansion.

Plant architecture is crucial for rapeseed breeding. Here, we demonstrate the involvement of , a transcription factor for ETHYLENE RESPONSE FACTOR (ERF), in the regulation of plant architecture in . is a member of the ERF family group X-a, encoding a putative 252-amino acid (aa) protein, which harbours the AP2/ERF domain and the conserved CMX-1 motif.

Increasing grain yield has always been the primary goal of crop breeding. KLUH/CYP78A5 has been shown to affect seed size in several plant species, but the relevant molecular mechanism is still unclear and there are no reports of this gene contributing to yield. Here, we demonstrate that modified expression of TaCYP78A5 can enhance wheat grain weight and grain yield per plant by accumulating auxin.

Wheat grain development is a robust biological process that largely determines grain quality and yield. In this study, we investigated the grain transcriptome of winter wheat cv. Xiaoyan-6 at four developmental stages (5, 10, 15, and 20 days post-anthesis), using high-throughput RNA sequencing (RNA-Seq).

Studies have shown chemopreventive and/or chemotherapeutic effects of several curcumin-based combinatorial treatments on colorectal cancer cells. However, their in vivo effects remain unclear. This study has demonstrated the therapeutic effect of curcumin and oxaliplatin, alone or in combination, on subcutaneously xenografted LoVo human colorectal cancer cells in immunodeficient (nu/nu) mice in vivo.
