antirrhinum cymbalaria/프롤린

Plants carrying the floricaula (flo) mutation cannot make the transition from inflorescence to floral meristems and have indeterminate shoots in place of flowers. The flo-613 allele carries a Tam3 transposon insertion, which allowed the isolation of the flo locus. The flo gene encodes a putative

ptl1, a gene expressed specifically in pistil transmitting tissue of Antirrhinum flowers, encodes a protein with similarity to plant extensins. The protein is rich in proline (28%) and serine (9%) and contains several proline-rich repetitive amino acid motifs found in other extensin-like proteins.

CONCLUSIONS A basic helix-loop-helix (bHLH) transcription factor gene from Antirrhinum, AmDEL , increases flavonoids accumulation and enhances salt and drought tolerance via up-regulating flavonoid biosynthesis, proline biosynthesis and ROS scavenging genes in transgenic Arabidopsis. In plants,
