A 'wiring diagram' for sink strength traits impacting wheat yield potential

Gustavo A. Slafer et al.

Summary: By reviewing the interacting processes determining sink strength and yield potential in wheat, and visualizing them in a set of 'wiring diagrams', the main traits determining sink strength were identified and research gaps were highlighted for achieving gains in sink strength. In the pre-anthesis phase, grain number could be increased through enhanced spike growth and improved fruiting efficiency. In the post-anthesis phase, grain sink strength could be augmented through manipulation of grain size potential and improving spike vascular architecture. The wiring diagrams provide a potential workspace for yield improvement in wheat and other field crops.

Out of Africa: characterizing the natural variation in dynamic photosynthetic traits in a diverse population of African rice (Oryza glaberrima)

Sophie B. Cowling et al.

Summary: African rice (Oryza glaberrima) exhibits extensive natural variation in photosynthetic traits, photoprotection, and stomatal conductance. These dynamic traits are important for the adaptation of O. glaberrima to diverse African environments and have value for gene discovery and crop improvement.

Advances in field-based high-throughput photosynthetic phenotyping

Peng Fu et al.

Summary: High-throughput phenotyping of photosynthesis is crucial for improving crop yield. Gas exchange techniques have revolutionized plant research but are limited by equipment and personnel availability for high-throughput phenotyping. Remote sensing techniques offer the potential to assess photosynthesis at finer spatial scales. This review outlines the interests and advances in high-throughput techniques for characterizing photosynthesis and discusses the current limitations, bottlenecks, and opportunities facing this field.

Mining for allelic gold: finding genetic variation in photosynthetic traits in crops and wild relatives

Robert E. Sharwood et al.

Summary: Improving photosynthetic traits in crops is crucial for increasing yield potential and crop resilience. The use of synthetic biology and genetic technologies allows for the exploration of genetic resources in gene banks to discover novel allelic variation and accelerate genetic progress in crop breeding programs. This article discusses strategies to selectively target allelic variation in key photosynthetic genes and the deployment of this variation through gene editing in modern elite materials.

High sink strength prevents photosynthetic down-regulation in cassava grown at elevated CO2 concentration

Ursula M. Ruiz-Vera et al.

Summary: The study found that increased CO2 concentrations can enhance the sink strength of cassava roots, potentially increasing cassava yields. However, differences in resource allocation between cultivars must be considered when selecting candidates for improvement.

Trehalose 6-phosphate promotes seed filling by activating auxin biosynthesis

Tobias Meitzel et al.

Summary: Plants undergo various developmental transitions, including the interaction between sugars and hormones during seed development. By modulating the content of the signaling sugar trehalose 6-phosphate (T6P), the biosynthesis of the key plant hormone auxin can be stimulated, facilitating seed filling processes. This study provides insight into how a metabolic signal like T6P governs hormonal control in crop plants.

What happens at night? Physiological mechanisms related to maintaining grain yield under high night temperature in rice

Jiemeng Xu et al.

Summary: High night temperature (HNT) has negative effects on rice yield, mainly by reducing spikelet number per panicle leading to yield decrease. HNT enhances nighttime reduction of non-structural carbohydrates (NSC) in stem tissue, negatively correlated with yield. HNT weakens the relationship between NSC remobilization and harvest index.

Ear photosynthesis in C3 cereals and its contribution to grain yield: methodologies, controversies, and perspectives

Eduardo A. Tambussi et al.

Summary: This review examines the contribution of ear photosynthesis to grain filling in C-3 cereals, highlighting the increasing role of ear photosynthesis in modern wheat germplasm and its potential to improve grain yield under resource-limitation. Evidence suggests genetic variability in ear contribution, supporting the existence of C-3 metabolism and indicating the ear as a dehydration avoider organ under drought stress. More research is needed to explore the thermal balance and underlying morphological and physiological traits related to ear productivity.

Wheat root systems as a breeding target for climate resilience

Eric S. Ober et al.

Summary: Larger genetic gains in yield are needed to meet future demand, and improving root systems could enhance climate resilience. Understanding the genetic control of root initiation, growth, and development is crucial for breeders to navigate, but also offers opportunities for improvement. Focusing on root system architecture in wheat can help enhance crop improvement and food security.

Variation between rice accessions in photosynthetic induction in flag leaves and underlying mechanisms

Liana G. Acevedo-Siaca et al.

Summary: Research shows that there is significant variation in photosynthesis of rice flag leaves under steady and non-steady-state conditions, with no significant correlation between the two. Additionally, the photosynthetic traits of flag leaves do not directly correlate with those of leaves in the vegetative growth stage.

Perspectives on improving light distribution and light use efficiency in crop canopies

Rebecca A. Slattery et al.

Summary: In natural settings, plants compete for resources such as light to enhance survival and adaptability, while in modern agriculture, monoculture crop production focuses on overall yield and cooperation, potentially selecting the best competitors unintentionally rather than the best cooperators. Overinvestment in increasing light interception has led to sub-optimal light use efficiency and constrained crop yield improvement. Agricultural research suggests potential strategies for improving crop yield and closing the yield gap, including balancing light distribution and introducing alternative pigment types.

30 years of free-air carbon dioxide enrichment (FACE): What have we learned about future crop productivity and its potential for adaptation?

Elizabeth A. Ainsworth et al.

Summary: Research on the effects of elevated CO2 levels on crop yields shows that an increase of around 200 ppm resulted in an 18% increase in yield for C3 crops. However, nitrogen deficiency and warming had negative effects on this increase. Additionally, it was found that C4 crops were not more productive in elevated CO2 levels, except under drought conditions.
