DOI: 10.1002/ajb2.1196
Abstract: PREMISE OF THE STUDY The densities of veins and stomata govern leaf water supply and gas exchange. They are coordinated to avoid overproduction of either veins or stomata. In many species, where leaf area is… read more here.

DOI: 10.1002/ajb2.1378
Abstract: PREMISE While essential for photosynthesis, excess light can damage plants. We investigated how growth light conditions affect two photoprotective strategies, chloroplast movement and nonphotochemical quenching (NPQ), as well as electron transport rates (ETR), and the… read more here.

DOI: 10.1007/s11120-017-0385-8
Abstract: It has previously been shown that the long-term treatment of Arabidopsis thaliana with the chloroplast inhibitor lincomycin leads to photosynthetic membranes enriched in antennas, strongly reduced in photosystem II reaction centers (PSII) and with enhanced… read more here.

DOI: 10.1007/s11120-017-0475-7
Abstract: Cyanobacteria possess a family of one-helix high-light-inducible proteins (HLIPs) that are widely viewed as ancestors of the light-harvesting antenna of plants and algae. HLIPs are essential for viability under various stress conditions, although their exact… read more here.

DOI: 10.1007/s11120-018-0558-0
Abstract: Non-photochemical quenching (NPQ) is a fast acting photoprotective response to high light stress triggered by over excitation of photosystem II. The mechanism for NPQ in the globally important diatom algae has been principally attributed to… read more here.
