β-Carboxysomal proteins assemble into highly organized structures in Nicotiana chloroplasts.
The Plant Journal, 2014 The photosynthetic efficiency of C3 plants suffers from the reaction of ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) with O2 instead of CO2 , leading to the costly process of photorespiration.

Phosphoproteins and protein-kinase activity in isolated envelopes of pea (Pisum sativum L.) chloroplasts [PDF]
, 1985 A protein kinase was found in envelope membranes of purified pea (Pisum sativum L.) chloroplasts. Separation of the two envelope membranes showed that most of the enzyme activity was localized in the outer envelope.

American Journal of Botany, EarlyView.Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

Frontiers in Plant Science, 2019 Tomato is the most important horticultural crop worldwide. Domestication has led to the selection of highly fruited genotypes, and the harvest index (HI), defined as the ratio of fruit yield over total plant biomass, is usually employed as a biomarker of

The biosynthesis of galactolipids in red clover (Trifolium pratense) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry [PDF]
, 1972 Galactolipids occur in all cells capable of the photosynthetic evolution of oxygen. The main galactolipids are monogalactosyl diglyceride (MGDG), digalactosyldiglyceride (DGDG) and sulfolipid (SL), MGDG being the most abundant.

A Receptor Component of the Chloroplast Protein Translocation Machinery [PDF]
, 1994 The chloroplast outer envelope protein OEP86 functions as a receptor in precursor protein translocation into chloroplasts. Sequence analysis suggests that the precursor of OEP86 is directed to the chloroplast outer envelope by a cleavable, negatively ...

American Journal of Botany, EarlyView.Abstract Premise Research on neutral and adaptive processes that lead to the divergence of species and populations is a crucial component in evolutionary and conservation genetics. Agave sobria is an endemic group of subspecies scattered on canyons along a latitudinal gradient and distinct environments of the Baja California Peninsula, Mexico.

Thioredoxin-dependent regulatory networks in chloroplasts under fluctuating light conditions
Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 Plants have adopted a number of mechanisms to restore redox homeostasis in the chloroplast under fluctuating light conditions in nature. Chloroplast thioredoxin systems are crucial components of this redox network, mediating environmental signals to ...

Floral scent of artificial hybrids between two Schiedea species that share a moth pollinator
American Journal of Botany, EarlyView.Abstract Premise In flowering plants, pollinators' ability to recognize chemical displays of hybrids may erode reproductive barriers. Hybrids may produce novel or altered floral scent blends that are unattractive, or scents similar to either parent that remain attractive and promote backcrossing.

Phosphorylation of chloroplast ribulose bisphosphate carboxylase/oxygenase small subunit by an envelope-bound protein kinase in situ [PDF]
, 1983 A new protein kinase of the cAMP independent type was found to be bound to the outer envelope membrane of spinach chloroplasts. While stimulated by Mg2+ and inhibited by ADP, the enzyme showed no response to conventional protein substrates and was ...
