R; enhanced resistance compared with wild-type plants; S, enhanced susceptibility compared with wild-type plants.
Enhanced resistance to downy mildew was not correlated with increased plant defense responses in comt1 mutant, but coincided with a higher frequency of oomycete sexual reproduction within mutant tissues.
Genes from Aspergillus nidulans (An), Phaseolus vulgaris (Pv) and Stylosanthes humilis (Sh).
RNA interference constructs were made by a combined ligation/recombination (LR) method using plasmid pIPKTA30N as the final GATEWAY destination vector (Bhuiyan et al., 2009) and a self-complementary hairpin RNA (hpRNA) of CAD gene, under the control of 35S CaMV promoter, was used to silence CAD expression (Wróbel-Kwiatkowska et al., 2007).
