“…The proportions of Citrobacter , Acinetobacter , and Pseudomonas significantly increased in response to drought treatment, while Phormidium was enriched under well‐watered conditions. Further experiments aimed at studying the effects of molecules (e.g., elicitors, growth promoting molecules) produced by rhizosheath taxa on plant growth and fitness and plant responses to these commensal microbes (e.g., transcription, alternative splicing, or translational control) are needed to increase our understanding of plant–microorganism communication and rhizosheath function under drought conditions (Zhang et al, 2020; Chen et al, 2020a, 2020b, 2020c).…”

The rhizosheath, a layer of soil grains that adheres firmly to roots, is beneficial for plant growth and adaptation to drought environments. Switchgrass is a perennial C4 grass which can form contact rhizosheath under drought conditions. In this study, we characterized the microbiomes of four different rhizocompartments of two switchgrass ecotypes (Alamo and Kanlow) grown under drought or well-watered conditions via 16S ribosomal RNA amplicon sequencing. These four rhizocompartments, the bulk soil, rhizosheath soil, rhizoplane, and root endosphere, harbored both

“…(2019) found that several BSKs have diverse splicing transcripts, which are expressed in different tissues and respond to various stimuli, indicating a novel post‐transcriptional regulation pattern in BSK genes. Sequential window acquisition of all theoretical fragment ion spectra MS (SWATH‐MS) has emerged to detect AS and quantify proteome dynamics (Blank‐Landeshammer et al ., 2019; Chen et al ., 2020a,b, 2021a,b; Zhu et al ., 2020). Using OE‐ ZmBSK1 and RNAi‐ ZmBSK1 transgenic lines, we would like to find more targets that are regulated by ZmBSK1 through SWATH‐MS and transcriptome analysis in future.…”

BRASSINOSTEROID‐SIGNALING KINASE 1 phosphorylating CALCIUM/CALMODULIN‐DEPENDENT PROTEIN KINASE functions in drought tolerance in maize

Drought stress seriously limits crop productivity. Although studies have been carried out, it is still largely unknown how plants respond to drought stress. Here we find that drought treatment can enhance the phosphorylation activity of brassinosteroid-signaling kinase 1 (ZmBSK1) in maize (Zea mays).Our genetic studies reveal that ZmBSK1 positively affects drought tolerance in maize plants. ZmBSK1 localizes in plasma membrane, interacts with calcium/calmodulin (Ca 2+ /CaM)dependent protein kinase (ZmCCaMK), and phosphorylates ZmCCaMK. Ser-67 is a crucial phosphorylation site of ZmCCaMK by ZmBSK1.Drought stress enhances not only the interaction between ZmBSK1 and ZmCCaMK but also the phosphorylation of Ser-67 in ZmCCaMK by ZmBSK1. Furthermore, Ser-67 phosphorylation in ZmCCaMK regulates its Ca 2+ /CaM binding, autophosphorylation and transphosphorylation activity, and positively affects its function in drought tolerance in maize.Our results reveal an important role for ZmBSK1 in drought tolerance and suggest a direct regulatory mode of ZmBSK1 phosphorylating ZmCCaMK.

“…In recent years, research on splicing in plants has also garnered much interest. For instance, studies on the stress response networks of splicing-related proteins and alternative splicing under abiotic stress have been reported ( Chen et al, 2020a , b ; Punzo et al, 2020 ). Splicing plays pivotal roles in plant life ( Chen et al, 2020c ).…”

Phylogenetic Analysis of the Plant U2 snRNP Auxiliary Factor Large Subunit A Gene Family in Response to Developmental Cues and Environmental Stimuli

In all organisms, splicing occurs through the formation of spliceosome complexes, and splicing auxiliary factors are essential during splicing. U2AF65 is a crucial splicing cofactor, and the two typical RNA-recognition motifs at its center recognize and bind the polypyrimidine sequence located between the intron branch site and the 3′-splice site. U2AF65A is a member of the U2AF65 gene family, with pivotal roles in diseases in mammals, specifically humans; however, few studies have investigated plant U2AF65A, and its specific functions are poorly understood. Therefore, in the present study, we systematically identified U2AF65A in plant species from algae to angiosperms. Based on 113 putative U2AF65A sequences from 33 plant species, phylogenetic analyses were performed, followed by basic bioinformatics, including the comparisons of gene structure, protein domains, promoter motifs, and gene expression levels. In addition, using rice as the model crop, we demonstrated that the OsU2AF65A protein is localized to the nucleus and cytoplasm, and it is involved in responses to various stresses, such as drought, high salinity, low temperature, and heavy metal exposure (e.g., cadmium). Using Arabidopsis thaliana and rice mutants, we demonstrated that U2AF65A is involved in the accumulation of plant biomass, growth of hypocotyl upon thermal stimulation, and reduction of tolerance of high temperature stress. These findings offer an overview of the U2AF65 gene family and its stress response functions, serving as the reference for further comprehensive functional studies of the essential specific splicing cofactor U2AF65A in the plant kingdom.
