Overexpression of beta-carotene hydroxylase enhances stress tolerance in Arabidopsis [PDF]
Plant stress caused by extreme environmental conditions is already a principal reason for yield reduction in crops. The threat of global environment change makes it increasingly important to generate crop plants that will withstand such conditions ...

Diatom triacylglycerol metabolism: from carbon fixation to lipid droplet degradation
ABSTRACT Diatoms are a prominent microalgae family that has attracted interest for its production of molecules of biotechnological interest. Their fatty acid profile is rich in health‐beneficial omega‐3 eicosapentaenoic acid (EPA). Furthermore, under nutrient‐deprived conditions, many diatom species, notably Phaeodactylum tricornutum, Thalassiosira ...

Mechanisms of light harvesting by photosystem II in plants
Light harvesting by photosystem II (PSII) in plants is highly efficient and acclimates to rapid changes in the intensity of sunlight. However, the mechanisms of PSII light harvesting have remained experimentally inaccessible.

Twin‐arginine translocation D (TatD) homologs are found across all kingdoms, with debated roles in DNA degradation and protein quality control in unicellular organisms. We characterize TATDN1, the mammalian TatD orthologue, as a proteostatic stress‐responsive cytosolic protein dispensable for DNA degradation.

Characterisation of a chlororespiratory pathway in Beta vulgaris and Trifolium repens : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology at Massey University, New Zealand [PDF]
The chloroplast respiratory pathway (chlororespiration) is postulated to interact with the photosynthetic pathway through the plastoquinone (PQ) pool. Two enzymes are proposed to operate in the pathway: an NAD(P)H dehydrogenase that is homologous to the ...

The permeability of the thylakoid membrane for protons
Parallel measurements of light‐induced proton gradients and of electron transport rates were used to characterize proton efflux in lettuce chloroplasts. Proton efflux mediated by the chloroplast H+‐ATPase was resolved from nonspecific leakage, through its dependence on the ratio of internal to external proton concentrations; proton leakage was ...

Localization of a 64-kDa phosphoprotein in the lumen between the outer and inner envelopes of pea chloroplasts [PDF]
The identification and localization of a marker protein for the intermembrane space between the outer and inner chloroplast envelopes is described. This 64-kDa protein is very rapidly labeled by [γ-32P]ATP at very low (30 nM) ATP concentrations and the ...

Abstract Until recently, the lack of three‐dimensional visualisation of whole cells at the electron microscopic (EM) level has led to a significant gap in our understanding of the interaction of cellular organelles and their interconnection. This is particularly true with regard to the role of the endoplasmic reticulum (ER).

Purification and Characterization of a Chloroplast Outer-Envelope-Bound, ATP-Dependent Protein Kinase [PDF]
An ATP-dependent protein kinase was partially purified from isolated outer envelope membranes of pea (Pisum sativum L., Progress No. 9) chloroplasts. The purified kinase had a molecular weight of 70 kilodaltons, as determined by sodium dodecyl sulfate ...
