Abstract
In recent years a novel family of calmodulinbinding transcription activators CAMTAs has been reported in various species The CAMTAs share a conserved domain organization with a CG1 DNAbinding domain a transcription factor immunoglobulin domain several ankyrin repeats a calmodulinbinding domain and a varying number of IQ motifs CAMTAs participate in transcriptional regulation by recognizing and binding to a specific ciselement G/A/CCGCGC/G/T Plants suffer from the environmental challenges including abiotic and biotic stresses Investigations in various plant species indicate a broad range of CAMTA functions involved in developmental regulation environmental stress response and hormone cross talk In this review we focus on the expression patterns and biological functions of CAMTAs to explore their probable applications in biotechnology Furthermore the identification and phylogenetic analysis of CAMTAs in crops could open new perspectives for enhancing stress tolerance which could lead to improved crop production
