Abg1: a novel gene up‐regulated by abscisic acid in guard cells of Vicia faba L.

Show Summary Details

Preview

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.

Keywords: Abscisic acid; guard cell; gene expression; Vicia faba.
