Expression profile of cystatin gene family in alfalfa (Medicago sativa L.) related to biotic and abiotic stress response.

ABSTRACT:

Background

Cystatins are cysteine protease inhibitor in plant and animal that not only regulates the intracellular transport of endogenous proteins in plants but also plays an important role in plant defense against biotic and abiotic stresses. However, the cystatin gene family in alfalfa remains poorly characterized.

Result

In this study, 55 cystatin genes distributed across 18 chromosomes in alfalfa were identified. GO enrichment analysis indicated that the 55 MsCYS genes were primarily associated with cysteine-type endopeptidase inhibitor activity. These genes were classified into six distinct subgroups, with each containing one or two typical cystatin domains. Analysis of cis-acting regulatory elements suggested the potential involvement of MsCYS genes in stress response
