“…The Filamin gene family is mainly localized in cell membranes and has been reported to be involved in the composition of the human cytoskeleton, cancer cell metastasis and certain growth processes [ 14 , 15 , 16 , 17 ]. GEX2, a member of the Filamin gene family in plants, plays important roles in the processes of sperm recognition and fusion in Arabidopsis [ 3 , 20 , 21 , 22 ], Zea mays [ 24 , 25 , 26 ] and Chlamydomonas [ 27 , 28 ]. Due to the lack of research about Filamin gene family members in cotton, this paper conducted a systematic study on the cotton Filamin gene family and screened out genes that may have the same function as Arabidopsis Filamin gene family members, which was determined according to the structure, expression, evolutionary analysis and interaction analysis of these genes.…”
