|a Dihydrolipoyl acyltransferase (EC 2.3.1.12), a branched-chain α-ketoacid dehydrogenase E2 subunit (BCE2), catalyzes the transfer of the acyl group from the lipoyl moiety to coenzyme A. However, the role of BCE2 responding to biotic stress in plant is not clear. In this study, we cloned and characterized a BCE2 gene from potato, namely StBCE2, which was previously suggested to be involved in Phytophthora infestans-potato interaction. We found that the expression of StBCE2 was strongly induced by both P. infestans isolate HB09-14-2 and salicylic acid. Besides, when the homolog of StBCE2 in Nicotiana benthamiana named NbBCE2 was silenced, plants showed increased susceptibility to P. infestans and reduced accumulation of hydrogen peroxide (H2O2). Furthermore, we found that a marker gene NbrbohB involved in the production of reactive oxygen species, was also suppressed in NbBCE2-silenced plants. However, silencing of NbBCE2 had no significant effect on the hypersensitive responses trigged by INF1, R3a-AVR3a(KI) pair or Rpi-vnt1.1-AVR-vnt1.1 pair. Our results suggest that BCE2 is associated with the basal resistance to P. infestans by regulating H2O2 production
