Insights into Genes Encoding LEA_1 Domain-Containing Proteins in Cyperus esculentus, a Desiccation-Tolerant Tuber Plant.

ABSTRACT: LEA_1 domain-containing proteins constitute a class of late-embryogenesis-abundant proteins that are highly hydrophilic and predominantly accumulate in mature seeds. Though LEA_1 proteins have been proven to be essential for seed desiccation tolerance and longevity, little information is available on their roles in non-seed storage organs. In this study, a first genome-wide characterization of the LEA_1 gene family was conducted in tigernut (Cyperus esculentus L., Cyperaceae), whose underground tubers are desiccation tolerant with a moisture content of less than 6%. Five family members identified in tigernut are comparative to four to six found in seven other Cyperaceae plants, but relatively more than three reported in Arabidopsis.
