1 Napin and oleosin transcripts were detected sooner following treatment with ABA than JA. Treatment of MDEs with ABA plus JA gave an additive accumulation of both napin and oleosin mRNA, the absolute amount being dependent on the concentration of each hormone. jasmonic acid LOW QUALITY PROTEIN: oleosin-B1 Brassica napus
2 Napin and oleosin transcripts were detected sooner following treatment with ABA than JA. Treatment of MDEs with ABA plus JA gave an additive accumulation of both napin and oleosin mRNA, the absolute amount being dependent on the concentration of each hormone. jasmonic acid LOW QUALITY PROTEIN: oleosin-B1 Brassica napus
3 Based on these results with the MDE system, it is possible that embryos of B. napus use endogenous JA to modulate ABA effects on expression of both napin and oleosin. In addition, JA could play a causal role in the reduction of ABA that occurs during late stages of seed development. jasmonic acid LOW QUALITY PROTEIN: oleosin-B1 Brassica napus
