Abstract The cellulose synthase gene superfamily, including Cellulose synthase A (CesA) and cellulose synthase-like (Csl) gene families, is responsible for the synthesis of cellulose and hemicellulose, respectively. The CesA/Csl genes are vital for abiotic stress resistance and shoot tenderness regulation of tea plants (Camellia sinensis). However, the CesA/Csl gene family has not been extensively studied in tea plants. Here, we identified 53 CsCesA/Csl genes in tea plants. These genes were grouped into five subfamilies (CsCesA, CsCslB, CsCslD, CsCslE, CsCslG) based on the phylogenetic relationships with Arabidopsis and rice. The analysis of chromosome distribution, gene structure, protein domain and motif revealed that most genes in CsCesA,… More >

Abstract As a macronutrient, Phosphorus (P) takes many roles in plant growth and development. It should be significant to explore the molecular mechanism of low-phosphorus stress response of plants. Phosphate starvation response (PHR) transcription factors play important roles in response to phosphorus deficiency stress in plants. In this study, we isolated a gene related to the plant phosphorus signaling system from the acid-soil-resistant centipedegrass (Eremochloa ophiuroides [Munro] Hack.), termed EoPHR2. The subcellular localization of EoPHR2 protein was observed to be nuclear located. The expression patterns of EoPHR2 in different tissues and Al/Pi-stress conditions were analyzed by qRT-PCR, they More >
