Summary: ZmAGA1 overexpression in Arabidopsis reduces RFOs and galactinol content in seeds, leading to increased seed germination percentage under stress conditions, but decreased seed aging tolerance. Manipulation of ZmAGA1 expression can potentially regulate maize seed germination and aging tolerance simultaneously.

Summary: To improve repeatability and reproducibility in quantitative susceptibility mapping (QSM) of the liver, an optimized regularized reconstruction algorithm for abdominal QSM was developed. The algorithm incorporates estimates of data reliability and anatomical priors, resulting in higher quality susceptibility maps. Evaluations show that the proposed method outperforms the standard method in terms of linear correlation, test-retest repeatability, and reproducibility across different acquisition protocols.

Summary: Soybean is the most important source of protein meal globally, with the quantitative trait loci (QTL) cqSeed protein-003 on chromosome 20 exhibiting the highest additive effect among all protein QTLs in this crop. Through genetic mapping and candidate gene downregulation, the insertion/deletion variant in Glyma.20G85100 is identified as the likely gene underlying this significant QTL.

Summary: Field pennycress is a new winter annual cash cover crop with high oil content and seed yield. A genome-wide association study (GWAS) was conducted to identify marker trait associations for seed size and composition related traits. The study found significant marker-trait associations and identified candidate genes that can accelerate pennycress breeding progress.

Summary: The research suggests that many plant species growing on metalliferous soils can accumulate and tolerate high levels of nickel, a trait that has evolved independently multiple times in different plant families. Analysis reveals the presence of genes encoding functions related to nickel hyperaccumulation in these species, including biosynthesis of specialized metabolites and cell wall organization. Additionally, high expression of IREG/Ferroportin transporters is recurrently associated with nickel hyperaccumulation in plants.

Summary: This review highlights the importance of plant micronutrient homeostasis for healthy nutrition and sustainable agriculture. Providing sustainable and nutritious food for the growing population is a major challenge. Micronutrient deficiencies adversely affect crop production, nutritional value, and human health. The review calls for awareness on the relevance of micronutrients in crop production and quality, emphasizing the need for better micronutrient nutrition in human populations.

Summary: The hydrogen isotopic composition of water in the early Solar System was determined by the capture of nebular hydrogen and the existence of a nebular gas reservoir. The hydrogen isotopes also correlate with oxygen and nitrogen isotopes, indicating the formation of planetary reservoirs within the first 200,000 years of the Solar System.

Summary: The study finds that there are two copies of NRAMP3 metal transporters in the poplar genome, one of which retains the original function of releasing metals stored in vacuoles in Arabidopsis, while the other copy has acquired a new function in controlling the cell-to-cell transport of manganese in the Trans-Golgi Network. This research provides a clear case of neofunctionalization through a change in the subcellular localization of a metal transporter and evidence for the involvement of the secretory pathway in the cell-to-cell transport of manganese.

Summary: A study has investigated how plant roots respond to mechanical compression using a microfluidic system. The researchers found that lateral pressure on the roots resulted in moderate elastic deformation of the root cells and an increase in calcium signaling. They also observed that repeated pressure stimuli led to a decrease in the calcium signal. These findings contribute to our understanding of how roots adapt to mechanical cues in the soil.
