Taxon: wheat ✕

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Title

Effects of water stress on photochemical function and protein metabolism of photosystem II in wheat leaves

Jun Xian He; Jun Wang; Hou Guo Liang Physiologia Plantarum 1995. doi:10.1111/j.1399-3054.1995.tb05130.x

Other claims from this paper (7)

Intervention effect Mild leaf water deficit did not significantly affect PSII activity in wheat.
Intervention effect Extreme water stress inhibited PSII DCIP photoreduction by about 25%.
Intervention effect DPC did not reverse inhibited PSII DCIP photoreduction.
Mechanism Water stress was inferred not to affect electron donation to PSII.
Association Major PSII proteins, including D1 and D2, declined on a chlorophyll basis as water stress increased.
Intervention effect Water stress impaired the potential synthesis of chloroplast proteins from their mRNAs.
Mechanism Water-stress effects on PSII protein metabolism may explain damage to PSII photochemistry.
