Advanced Science, EarlyView.TaPPR13, a PPR protein family gene in wheat is activated by TaBZR2 to enhance drought stress tolerance and photosynthetic capacity. It achieves this by interacting with TaAOR1 and TaSIG5 to improve antioxidant defense and regulate chloroplast gene expression. Abstract The wheat (Triticum aestivum) brassinazole‐resistant 2 (TaBZR2) gene is identified as

The Penalty of a Long, Hot Summer. Photosynthetic Acclimation to High CO2 and Continuous Light in “Living Fossil” Conifers [PDF]
, 2003 Deciduous forests covered the ice-free polar regions 280 to 40 million years ago under warm “greenhouse” climates and high atmospheric pCO2. Their deciduous habit is frequently interpreted as an adaptation for minimizing carbon losses during winter, but ...

Carboxysome encapsulation of the CO2-fixing enzyme Rubisco in tobacco chloroplasts
Nature Communications, 2018 A long-term strategy to enhance global crop photosynthesis and yield involves the introduction of cyanobacterial CO2-concentrating mechanisms (CCMs) into plant chloroplasts.

Probing the rice Rubisco–Rubisco activase interaction via subunit heterooligomerization [PDF]
Proceedings of the National Academy of Sciences, 2019 During photosynthesis the AAA+ protein and essential molecular chaperone Rubisco activase (Rca) constantly remodels inhibited active sites of the CO 2 -fixing enzyme Rubisco (ribulose 1,5-bisphosphate carboxylase/oxygenase) to release tightly bound sugar phosphates. Higher plant Rca is a crop improvement target, but

Advanced Science, EarlyView.Phytophthora capsici effector PcRD18 targets tomato GSNOR to disrupt NO homeostasis, promoting S‐nitrosylation of immune proteins like RBOHD. This suppresses ROS bursts and promotes pathogen infection. Mutation of the PcRD18‐binding sites of GSNOR avoids pathogen manipulation and offers a strategy to enhance crop resistance. Abstract Nitric oxide (NO),

Molecular and physiological analysis of flag leaf senescence and remobilization of assimilates in bread wheat under terminal drought stress [PDF]
مجله بیوتکنولوژی کشاورزی, 2017 In the physiological study of stem remobilization of assimilates during grain filling, mutant genetic materials are a valuable tool. Two advanced mutant lines of bread wheat (T-67-60 and T-65-7-1) along with their wild type (Tabasi Cv.) were planted at ...

Rate of photosynthetic induction in fluctuating light varies widely among genotypes of wheat. [PDF]
, 2019 Crop photosynthesis and yield are limited by slow photosynthetic induction in sunflecks. We quantified variation in induction kinetics across diverse genotypes of wheat for the first time.

Characteristics of the tomato chromoplast revealed by proteomic analysis [PDF]
, 2010 Chromoplasts are non-photosynthetic specialized plastids that are important in ripening tomato fruit (Solanum lycopersicum) since, among other functions, they are the site of accumulation of coloured compounds.

Evolutionary trends in Rubisco kinetics and their co-evolution with CO2 concentrating mechanisms.
The Plant Journal, 2019 Rubisco-catalyzed CO2 fixation is the main source of organic carbon in the biosphere. This enzyme is present in all domains of life with different forms (III, II, and I) and its origin goes back to 3,500 million years, when the atmosphere was anoxygenic.

Rubisco proton production can drive the elevation of CO2 within condensates and carboxysomes
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Rubisco is arguably the most abundant protein on Earth, and its catalytic action is responsible for the bulk of organic carbon in the biosphere. Its function has been the focus of study for many decades, but recent discoveries highlight that
