Genome-wide analysis uncovers CBL and CIPK family dynamics in grasses, indicating specific interactions in rice during osmotic stress.

Key Points

This research aims to characterize the evolutionary dynamics of CBL and CIPK gene families across selected grass species and their functional roles in stress responses.
Conducted genome-wide analysis of CBL and CIPK families in five Poaceae species.
Performed phylogenetic and synteny analyses to explore family expansion.
Analyzed promoter regions for cis-regulatory elements related to stress response.
Examined expression profiles of OsCBL and OsCIPK genes under various stress conditions using qRT-PCR.
Assessed protein interactions between OsCBL4 and CIPK pairs using Yeast Two-Hybrid and Luciferase Complementation Imaging.
Phylogenetic analysis showed significant segmental duplications contributing to gene family expansion.
Promoter analysis indicated OsCBL4 is heavily biased towards dehydration responsiveness with specific cis-elements.
OsCBL4 exhibited significant expression under osmotic stress but minimal response to ABA.
Protein interaction studies demonstrated exclusive interactions between OsCBL4 and certain PEG-responsive CIPKs.
