Other claims from this paper (6)
- Observation The 13S line showed higher non-photochemical quenching of chlorophyll fluorescence (NPQ) in its leaves.
- Intervention effect ROS production decreased in 13S plant leaves under low-temperature stress.
- Intervention effect AtNDB2 expression increased the mRNA numbers of the genes NDA2 and AOX1a.
- Mechanism The authors interpret the AtNDB2 result as confirming the possibility of an NDB2/NDA2-Q/QH2-AOX alternative pathway in 13S mitochondria.
- Intervention effect Under control conditions, AtNDB2 expression slightly increased Mn-SOD activity.
- Intervention effect Under cold stress, SOD isoform activity in 13S plant leaves was lower than in wild type.
