Expression

Organism Comment Expression
Arabidopsis thaliana isoform KCS20 mRNA expression is stimulated about 2fold by drought stress (air-drying for 6 h). Isoform KCS2/DAISY mRNA expression is stimulated about 4 fold at 200 mM mannitol, about 60fold at drought stress, about 3fold at 100 mM NaCl, and about 20fold at 0.1 mM abscisic acid up

General Information

General Information Comment Organism
malfunction complete loss of isoform KCS20 and KCS2 genes decreases the total wax content in stems and leaves by 20% and 15%, respectively. Kcs20 kcs2/daisy-1 double mutants exhibit significant reduction of C22 and C24 very-long-chain fatty acid derivatives but accumulation of C20 very-long-chain fatty acid derivatives in aliphatic suberin Arabidopsis thaliana
physiological function isoforms KCS20 and KCS2/DAISY are functionally redundant in the two-carbon elongation to C22 very-long-chain fatty acid that is required for cuticular wax and root suberin biosynthesis Arabidopsis thaliana
