Regulation of photosynthesis and water-use efficiency in pima and upland cotton species subjected to drought and recovery

Photosynthetica
Photosynthesis is extremely sensitive to drought and decreases due to co-occurring stomatal, mesophyll, and biochemical limitations. Few studies have shown the effects of a drought cycle (drought-rewatering) on photosynthesis and water-use efficiency ...

Canola Responses to Drought, Heat, and Combined Stress: Shared and Specific Effects on Carbon Assimilation, Seed Yield, and Oil Composition

Frontiers in Plant Science, 2018
Photosynthetic assimilation is remarkably altered by heat and drought, and this depends on the individual or combined occurrence of stressors and their respective intensities and durations.

Unified representation of the C3, C4, and CAM photosynthetic pathways with the Photo3 model

, 2019
Recently, interest in crassulacean acid metabolism (CAM) photosynthesis has risen and new, physiologically based CAM models have emerged. These models show promise, yet unlike the more widely used physiological models of C3 and C4 photosynthesis, their ...

The operation of two decarboxylases, transamination, and partitioning of C4 metabolic processes between mesophyll and bundle sheath cells allows light capture to be balanced for the maize C4 pathway. [PDF]

, 2013
The C4 photosynthesis carbon-concentrating mechanism in maize (Zea mays) has two CO2 delivery pathways to the bundle sheath (BS; via malate or aspartate), and rates of phosphoglyceric acid reduction, starch synthesis, and phosphoenolpyruvate regeneration

The HaMYB22–HaGST3.2 module mediates salt stress response in sunflower

Journal of Integrative Plant Biology, EarlyView.
The transcription factors HaMYB22, HaMYB120, and HaMYB121 cooperatively activate the transcription of the glutathione S‐transferase gene HaGST3.2, thereby facilitating the removal of reactive oxygen species induced by salt stress in sunflowers and improving their salt tolerance.

Partial Root-Zone Drying of Olive (Olea europaea var. "Chetoui") Induces Reduced Yield under Field Conditions [PDF]

, 2016
The productivity of olive trees in arid and semi-arid environments is closely linked to irrigation. It is necessary to improve the efficiency of irrigation techniques to optimise the amount of olive fruit produced in relation to the volume of water used.

Tandemly duplicated TaERF109 genes confer drought tolerance and post‐drought recovery in wheat

Journal of Integrative Plant Biology, EarlyView.
Tandemly duplicated TaERF109 transcription factor genes in wheat modulate growth traits and enhance drought tolerance by regulating the TaMADS56 transcription facto gene, cytokinin biosynthesis‐related genes, and nicotianamine synthase genes, revealing the critical role of tandemly duplicated genes in the coordination of stress responses and ...

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.

Leaf hydraulic conductance for a tank bromeliad: axial and radial pathways for moving and conserving water

Frontiers in Plant Science, 2013
Plants in the Bromeliaceae known as tank bromeliads essentially lack stems and absorptive roots and instead take up water from reservoirs formed by their overlapping leaf bases.

The IKU2/RLK7–MAPK–MINI3 signaling module controls endosperm cellularization timing to determine seed size in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The phosphorylation status of the WRKY transcription factor WRKY10/MINI3, controls the timing of endosperm cellularization in Arabiopsis, thus regulating final seed size, offering a molecular understanding that could inform future agricultural breeding strategies. ABSTRACT Seed size is a critical factor in determining crop yield.
