General Information

General Information Comment Organism
malfunction virus-induced gene silencing of BCAT results in abnormal leaf development and loss of apical dominance, suppressed expression of BCAT causes changes in various endogenous hormones and abnormal plant development that can be correlated with transcriptional induction of the KNOX genes, NTH15 and NTH23 Nicotiana benthamiana
