Abstract
Climate change is expected to make drought far more severe and frequent for plants all over the world ([Bartlett et al., 2016][1]). Drought affects yield, growth, and development of plants. Photosynthesis is particularly sensitive to drought stress, and when its efficiency decreases due to drought,
Highlights
Climate change is expected to make drought far more severe and frequent for plants all over the world (Bartlett et al, 2016)
PSII has a core that is conserved from cyanobacteria to vascular plants (Nickelsen and Rengstl, 2013), so studies in cyanobacteria should be directly applicable to crops
The subaerial cyanobacterium Nostoc flagelliforme is found in arid areas with daily high-light stress, and the photosynthetic membranes of N. flagelliforme are preserved during prolonged dehydration and recover rapidly during rehydration (Qiu et al, 2004)
Summary
Climate change is expected to make drought far more severe and frequent for plants all over the world (Bartlett et al, 2016). PSII is a thylakoid membrane integral protein complex of the electron transport chain that is sensitive to photodamage under drought. Deletion of these proteins or their cyanobacterial homologs DnaK and DnaJ, respectively, results in reduced photosynthetic efficiency in plants, whereas overexpression slows the degradation of oxygen-evolving complex proteins (Chen et al, 2010).
