Other claims from this paper (17)
- Intervention effect Flooding stress alters relative water content (RWC) in maize leaves.
- Intervention effect Flooding stress increases H2O2 content in maize leaves in vivo.
- Observation Programmed cell death occurred in maize leaves under flooding treatment.
- Observation A total of 32 differentially expressed spots were isolated from the maize leaf proteome.
- Observation 31 differentially expressed spots were identified by MALDI-TOF/TOF MS, representing 28 proteins.
- Observation The identified maize leaf proteins are related to energy metabolism and photosynthesis.
- Observation The identified maize leaf proteins are related to PCD, phytohormones and polyamines.
- Intervention effect TCTP expression increased in different degrees in stress-induced PCD systems, including heat-stressed rice protoplasts.
- Intervention effect Flooding increases SAMS2 mRNA expression in maize leaves.
- Intervention effect Flooding increases SAMDC mRNA expression in maize leaves.
- Intervention effect ACC synthase (ACS) mRNA expression is not found in maize leaves following flooding.
- Intervention effect ACC oxidase (ACO) mRNA expression is not found in maize leaves following flooding.
- Intervention effect Ethylene and polyamine concentrations increase in maize leaves in response to flooding.
- Mechanism Flooding stress damages the photosynthetic systems of maize, resulting in a disruption of energy metabolism.
- Mechanism The photosynthetic decline in flooded maize may be attributed to ROS production.
- Mechanism PCD may be regulated by TCTP, with a possible role for H2O2 in TCTP induction under flooding stress.
- Association Increased SAMS2 expression is closely associated with increased polyamine synthesis during flooding treatment in maize.
