Meta-analysis Detect Candidate Rice Genes Involved in Salt Tolerance

October 7, 2020

A genome-wide meta-analysis has been devised to help researchers in Agricultural Biotechnology Research Institute of Iran pinpoint the candidate genes that are involved in salt tolerance in rice. The results are published in BMC Plant Biology.

Salinity is one of the main causes of stress in crops, which impacts their growth and fertility.Thus, the researchers proposed an integrative meta-analysis strategy involving microarrays and RNA-seq data that will help to unearth the molecular mechanisms involved in salt tolerance.

A total of 3,449 differentially expressed genes (DEGs) were identified. Using meta-QTL analysis and literature review, the researchers detected 23 potential candidate genes that are involved in yield components and ion homeostasis traits; among which, there were many unreported salinity-responsive genes. Furthermore, more candidate genes were found which code for pectinesterase, peroxidase, transcription regulator, high-affinity potassium transporter, cell wall organization, protein serine/threonine phosphatase, and CBS domain-containing protein.
