Here, we found that anthocyanin was also involved in ascorbic acid biosynthesis and glycolysis under chilling stress.

Arabidopsis G-protein β subunit AGB1 represses abscisic acid signaling via attenuation of the MPK3-VIP1 phosphorylation cascade.

Heterotrimeric G proteins play key roles in cellular processes. Although phenotypic analyses of Arabidopsis Gβ (AGB1) mutants have implicated G proteins in abscisic acid (ABA) signaling, the AGB1-mediated modules involved in ABA responses remain unclear. We found that a partial AGB1 protein was localized to the nucleus where it interacted with ABA-activated VirE2-interacting protein 1 (VIP1) and mitogen-activated protein kinase 3 (MPK3).

Novel processing strategies to enhance the bioaccessibility and bioavailability of functional components in wheat bran.

Dietary fiber, polysaccharides and phenols are the representative functional components in wheat bran, which have important nutritional properties and pharmacological effects. However, the most functional components in wheat bran exist in bound form with low bioaccessibility. This paper reviews these functional components, analyzes modification methods, and focuses on novel solid-state fermentation (SSF) strategies in the release of functional components.

Here, we identified 6, 7, 14 and 14 GPDH genes derived from , , and , respectively. Phylogenetic analysis assigned these genes into three classes, and most of the genes within the family were expanded by whole-genome duplication (WGD) and segmental duplications.

Research Progress of PPR Proteins in RNA Editing, Stress Response, Plant Growth and Development.

RNA editing is a posttranscriptional phenomenon that includes gene processing and modification at specific nucleotide sites. RNA editing mainly occurs in the genomes of mitochondria and chloroplasts in higher plants. In recent years, pentatricopeptide repeat (PPR) proteins, which may act as trans-acting factors of RNA editing have been identified, and the study of PPR proteins has become a research focus in molecular biology.

RNA Editing and Its Roles in Plant Organelles.

RNA editing, a vital supplement to the central dogma, yields genetic information on RNA products that are different from their DNA templates. The conversion of C-to-U in mitochondria and plastids is the main kind of RNA editing in plants. Various factors have been demonstrated to be involved in RNA editing.

Genome-Wide Study of NOT2_3_5 Protein Subfamily in Cotton and Their Necessity in Resistance to .

The Negative on TATA-less (NOT) 2_3_5 domain proteins play key roles in mRNA metabolism and transcription regulation, but few comprehensive studies have focused on this protein family in plants. In our study, a total of 30 genes were identified in four cotton genomes: , , and Phylogenetic analysis showed that all the NOT2_3_5 domain proteins were divided into two classes. The genes were expanded frequently, and segmental duplication had significant effects in their expansion process.

Epigenetic Alteration Shaped by the Environmental Chemical Bisphenol A.

Bisphenol A (BPA) is extensively used in plastic products and epoxy resins. The epigenetic response to the environmental chemical BPA was involved in multiple dysfunctional categories, such as cancer, the reproductive system, metabolism, pubertal development, peripheral arterial disease, infant and childhood growth, and neurodevelopment outcomes. In this mini-review, we described the recent progress of the epigenetic effects of the environmental chemical BPA, including DNA methylation, histone methylation, and toxic epigenomics.

Promoter variants of Xa23 alleles affect bacterial blight resistance and evolutionary pattern.

Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is the most important bacterial disease in rice (Oryza sativa L.).

XA23 is an executor R protein and confers broad-spectrum disease resistance in rice.

The majority of plant disease resistance (R) genes encode proteins that share common structural features.
