A genome-wide analysis of the CDPK gene family in maize for the first time is presented and expression analyses suggested that maize C DPK genes are important components of maize development and multiple transduction pathways.Abstract:
Calcium-dependent protein kinases (CDPKs) have been shown to play important roles in various physiological processes, including plant growth and development, abiotic and biotic stress responses and plant hormone signaling in plants. In this study, we performed a bioinformatics analysis of the entire maize genome and identified 40 CDPK genes. Phylogenetic analysis indicated that 40 ZmCPKs can be divided into four groups. Most maize CDPK genes exhibited different expression levels in different tissues and developmental stages. Twelve CDPK genes were selected to respond to various stimuli, including salt, drought and cold, as well as ABA and H2O2. Expression analyses suggested that maize CDPK genes are important components of maize development and multiple transduction pathways. Here, we present a genome-wide analysis of the CDPK gene family in maize for the first time, and this genomic analysis of maize CDPK genes provides the first step towards a functional study of this gene family in maize.read more

TL;DR: A comprehensive analysis of AP2/ERF gene expression patterns in different tissues and fruit development stages by quantitative real-time PCR (qRT-PCR) showed that they played an important role in the growth and development of tartary buckwheat, and genes that might regulate flower and Fruit development were preliminarily identified.
Journal ArticleDOI
ZmCPK1, a calcium-independent kinase member of the Zea mays CDPK gene family, functions as a negative regulator in cold stress signalling.
TL;DR: The results identify ZmCPK1 as a negative regulator of cold stress signalling in maize as well as heterologous overexpression of Zm CPK1 in Arabidopsis thaliana yielded plants with altered acclimation-induced frost tolerance.
