Pollen tube emergence is mediated by ovary-expressed ALCATRAZ in cucumber

Cucumber is an important vegetable crop worldwide, which is mainly propagated by seed. The successful occurrence of double fertilization is the premise of seed production in angiosperms. Cucumber ALC homolog (CsALC) displayed a novel and positive function in pollen tube emergence process, and regulated female fertility by promoting CsRALF4/19 function during pollen tube guidance in cucumber. Overall design: Ovaries of wild type and Csalc mutant at 32 h after pollination were collected for RNA-seq analysis. Three biological replicates were performed.
