Abstract

Jasmonates are a new class of plant hormones that play important roles in plant development and plant defense. TheCOI1 gene was previously shown to be required for jasmonate-regulated plant fertility and defense. We demonstrated for the first time that COI1 interacts with theArabidopsis SKP1-LIKE1 (ASK1) to form a complex that is required for jasmonate action inplanta. Functional analysis by antisense strategy showed thatASK1 is involved in male fertility.
