SIB1‐SEC23A undergo ER to chloroplast relocalization to mediate immunity in Arabidopsis thaliana
Journal of Integrative Plant Biology, EarlyView.SEC23A mediates membrane trafficking between the endoplasmic reticulum (ER) and Golgi apparatus and interacts with the immunity protein SIGMA FACTOR‐BINDING PROTEIN1 in Arabidopsis. Under stress, both proteins relocate from the ER to chloroplasts, suppressing photosynthesis genes and enhancing defense genes.

Photoinhibition of photosynthesis in Antarctic lichen Usnea antarctica. I. Light intensity- and light duration-dependent changes in functioning of photosystem II [PDF]
, 2012 The paper deals with the differences in sensitivity of Antarctic lichen to photoinhibition. Thalli of Usnea antarctica were collected at the James Ross Island, Antarctica (57 deg 52 57 W, 63 deg 48 02 S) and transferred in dry state to the Czech Republic.

Journal of Phycology, EarlyView.Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Photoinhibition of Chloroplast Reactions. II. Multiple Effects [PDF]
Plant Physiology, 1966 Ultraviolet light inhibits the photoreduction of 2,6-dichlorophenolindo-phenol or nicotinamide adenine dinucleotide phosphate with water as the electron donor (evolution of oxygen) but not the photoreduction of nicotinamide adenine dinucleotide phosphate with ascorbate as the electron donor.

Regulation of Photosynthetic Electron Transport and Photoinhibition [PDF]
Current Protein & Peptide Science, 2014 Photosynthetic organisms and isolated photosystems are of interest for technical applications. In nature, photosynthetic electron transport has to work efficiently in contrasting environments such as shade and full sunlight at noon. Photosynthetic electron transport is regulated on many levels, starting with the energy transfer processes in antenna and

The light requirements for growth and photosynthesis in seagrasses with emphasis on Texas estuaries : a literature survey [PDF]
, 1993 During the last 20 years, seagrass communities throughout the world have experienced decreased productivity and distribution. These declines have often been attributed to decreased water transparency as a result of turbidity or shading by epiphytic algae.

New Phytologist, EarlyView.Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.

Antenna complexes protect Photosystem I from Photoinhibition [PDF]
BMC Plant Biology, 2009 Abstract Background Photosystems are composed of two moieties, a reaction center and a peripheral antenna system. In photosynthetic eukaryotes the latter system is composed of proteins belonging to Lhc family. An increasing set of evidences demonstrated how these polypeptides play a relevant physiological function in ...
