Abstract
A novel gene (abg1) was isolated by differential display RT-PCR from guard cells of Vicia faba L. Abg1 transcript accumulated in guard cells that were incubated with 5 µM S(+)-ABA for 1 h. The full-length abg1 cDNA was 753 bp, which included a 513 bp coding region. The deduced 17.8 kDa protein shared sequence similarity with several desiccation-related proteins reported in plants.
Key words: Abscisic acid, guard cell, gene expression, Vicia faba.
