Summary: Source-sink relationships play a crucial role in determining overall crop performance. Variations in source-sink dynamics between cultivated rice and wild rice contribute to differences in biomass and grain yield. The wild rice, Oryza australiensis, tends to prioritize the synthesis of structural carbohydrates for high biomass, while the cultivated rice, Oryza sativa cv. Nipponbare, favors high grain yield through the accumulation of transitory starch in the stem. Vascular features, sucrose transport, and sugar metabolic enzyme functions explain these differences in source-sink relationships.

Summary: The Arabidopsis transcription factor AtHB5 plays a crucial role in regulating carbon partitioning and sucrose transport from source to sink tissues. Mutation of AtHB5 leads to wider and more lignified stems, while overexpression of AtHB5 results in callose deposition. Additionally, AtHB5 has significant effects on plant biomass and seed yield.

Summary: The response of spinach plants to different light intensities was studied. Under low light conditions, plants showed reduced biomass accumulation and redirected photoassimilates to leaves for efficient light interception, with no changes in the photosynthetic process. Carbon partitioning favored starch synthesis under low light, resulting in an increase in the starch/sucrose ratio. The activity of enzymes involved in sucrose and starch synthesis decreased under lower light intensity, explaining the reduced accumulation of photoassimilates.

Summary: This study reveals an auxin signaling cascade regulating carbohydrate partitioning and reproductive organ development in rice. Elevated auxin levels in the rice dao mutant cause altered sucrose accumulation between source and sink tissues, resulting in closed spikelets, indehiscent anthers, and parthenocarpic seeds. The expression of OsARF18 and OsARF2 is significantly affected in the mutant, and their regulation of OsSUT1 contributes to the observed phenotypes.

Summary: This study examines the composition and carbohydrate profiles of three underutilized legumes, Vigna radiata, Vigna mungo, and Macrotyloma uniflorum. The legume accessions vary in their proximate composition and carbohydrate components, with Macrotyloma uniflorum having the highest carbohydrate content and Vigna radiata having the lowest. The different accessions also exhibit variations in starch and sugar contents. The unique characteristics of these legumes make them suitable for consumption and potential sources of nutraceuticals and pharmaceuticals.

Summary: Plants employ various adaptive strategies to respond to daylength variation, including adjustments in growth, photosynthesis, carbon utilization, and metabolic flux. Under short-day conditions, plants compensate for reduced CO2 fixation by enhancing photosynthetic rates and reducing respiration in the light, while also reducing the partitioning of glucose and increasing starch accumulation to sustain carbon availability during the longer night. Isotopic labeling results demonstrate substantial changes in the partitioning of amino acids and TCA cycle intermediates between rapidly and slowly turning over pools in response to different daylengths.

Summary: Reducing antenna size of photosystems and chlorophyll content can enhance photosynthetic efficiency and biomass accumulation, which is applicable to barley. The pale green hus1 mutant has a reduced chlorophyll content due to a mutation in the HvcpSRP43 gene, which is responsible for loading photosystem antenna proteins into thylakoid membranes. Additionally, the agronomic performance of hus1 plants is comparable to control plants under field conditions.

Summary: This study investigates the impact of cell wall modifications on plant development and the role of biomechanical alterations in seed and fruit growth. Mutants of Arabidopsis thaliana were used to study the function of gene families related to cell wall biogenesis. Disruption of genes involved in pectin maturation and hemicellulose deposition was found to strongly influence germination dynamics. Transcriptional regulators STK and LUH were shown to regulate specific aspects of cell wall properties, such as pectin distribution.
