Another “green revolution” is needed for crop yields to meet demands for food. The international C4 Rice Consortium is working toward introducing a higher-capacity photosynthetic mechanism—the C4 pathway—into rice to increase yield. The goal is to identify the genes necessary to install C4 photosynthesis in rice through different approaches, including genomic and transcriptional sequence comparisons and mutant screening.

Increasing crop yield and resilience with trehalose 6-phosphate: targeting a feast–famine mechanism in cereals for better source–sink optimization

TLDR
Targeting T6P both temporally and spatially offers great promise for large yield improvements in productive and marginal environments, and this opinion paper highlights this important breakthrough in fundamental science for crop improvement.

Exploring natural variation of photosynthesis in a site-specific manner: evolution, progress, and prospects

TLDR
Site-specific changes of photosynthesis, a relatively new concept, can be used to improve the productivity of critical food crops to mitigate the foreseen food crisis and hold a potential to enhance the yields of economically important C3 crops.

The next green movement: Plant biology for the environment and sustainability

TLDR
Recent efforts to engineer plants for better nitrogen and phosphorus use, enhanced carbon fixation, and environmental remediation and to understand plant-microbiome interactions showcase exciting future directions for translational plant biology.

Strategies for Optimizing Photosynthesis with Biotechnology to Improve Crop Yield

The world’s population is projected to increase to 9 billion by 2050 (Roberts 2011), while the availability of arable land will decrease as environmental degradation and destruction grow worse.

Comparative analyses of C4 and C3 photosynthesis in developing leaves of maize and rice

TLDR
To identify differences between C4 and C3 photosynthetic mechanisms, metabolites and gene expression in the developing leaves of Zea mays and Oryza sativa were profiled using a statistical method named the unified developmental model (UDM).

The C(4) plant lineages of planet Earth.

TLDR
Using isotopic screens, phylogenetic assessments, and 45 years of physiological data, it is now possible to identify most of the evolutionary lineages expressing the C(4) photosynthetic pathway, and is thus an outstanding system to study the mechanisms of evolutionary adaptation.

Phosphorylation of Phosphoenolpyruvate Carboxylase Is Not Essential for High Photosynthetic Rates in the C4 Species Flaveria bidentis1[OA]

TLDR
There were, however, no differences in the CO2 and light response of CO2 assimilation rates between wild-type plants and transgenic plants with low PEPC phosphorylation, showing that phosphorylated PEPC in the light is not essential for efficient C4 photosynthesis for plants grown under standard glasshouse conditions.
