Other claims from this paper (9)
- Intervention effect ABA-treated barley plants exhibited earlier stomatal closure under drought.
- Intervention effect ABA-treated barley plants showed increased expression of the ABA-responsive genes HvNCED1, HvBG8 and HvA22.
- Intervention effect ABA-treated barley plants maintained higher chlorophyll levels under drought conditions.
- Intervention effect Photosystem II activity, electron transport rate and number of active reaction centers were preserved in ABA-pretreated barley plants compared with drought-only plants.
- Intervention effect ABA pre-treatment led to enhanced expression of genes related to chromatin modifications, RNA metabolism and ABA signaling during drought in barley.
- Intervention effect Alternative splicing and isoform switching were significantly amplified in ABA-pretreated barley plants.
- Intervention effect Time- and dose-optimized ABA applications improved yield parameters including grain weight and seed area under drought.
- Intervention effect Time- and dose-optimized ABA applications mitigated spike sterility under drought conditions in barley.
- Mechanism ABA priming is proposed to accelerate stress-response pathways, promoting alternative splicing, isoform switching and chromatin modifications that enable transcriptome plasticity.
