Summary: Increasing soybean production is crucial for global food security and human health. This study shows that selecting soybean cultivars with larger seed sizes does not necessarily result in higher seed yield or protein content. In fact, it may even reduce seed yield. Additionally, there is a negative correlation between seed lipids content and hundred seed weight.

Summary: Seed size is crucial for agricultural development, influencing crop yield. It is regulated by the coordinated development of various components within the seed. Large seeds can enhance crop growth by providing more nutrients and displaying tolerance to abiotic stresses. The regulation of seed size involves multiple pathways, including genetic and hormonal mechanisms. This article provides a comprehensive overview of the regulatory network and potential strategies for improving yield, serving as a valuable reference for researchers in related fields.

Summary: Auxin plays an important role in the coordinated development of the embryo, endosperm, and seed coat during seed development. In this study, the distribution pattern and function of auxin during Arabidopsis seed development were investigated. It was found that auxin response signals exhibited a dynamic distribution pattern, with strong signals observed at specific locations in the seed coat. Auxin biosynthesis genes and auxin carriers were identified as contributing factors to the accumulation and polar distribution of auxin in the seed coat. Furthermore, the accumulation of auxin in the seed coat was found to regulate seed size. These findings provide valuable insights and tools for improving crop yields.

Summary: Comprehensive RNA-seq analyses were conducted on maize seed development to explore the mechanisms underlying seed development in maize. The study found that gene expression levels were largely nonadditive in hybrids and the pattern of cis-only or trans x cis played a crucial role in hybrid gene regulation during seed development. Weighted gene co-expression network (WGCNA) analysis identified several modules highly correlated with kernel weight, length, and width during seed development. The study also revealed the important role of ZmARF12, a transcription factor involved in auxin signal pathways, cell division, and seed size determination. The ZmARF12 mutant exhibited larger seed size and higher grain weight, confirming its role as a cell division repressor and a determinant of final seed size.

Summary: During early embryogenesis, the size of intracellular organelles decreases with overall cell size, and this size scaling is crucial for proper cellular function. The regulation of organelle size and organization is not well understood, but recent discoveries and the use of Xenopus as a model organism provide insights into these mechanisms and the significance of proper organelle size scaling.

Summary: This review analyzes the effects of nitrogen fertilizer on the growth and development of rapeseed, focusing on the mechanisms and gene regulation involved in nitrogen regulation of oil accumulation. The study found that the oil content of rapeseed seeds tends to decrease after nitrogen application. However, by screening elite germplasm resources with stable or improved oil content and investigating the molecular mechanisms of nitrogen regulation, it is possible to breed rapeseed varieties with high oil content.

A total of 33 pathotypes were identified, with two pathotypes accounting for 79.46% of the population. Most Indian wheat germplasm varieties possessed a high degree of resistance to leaf rust caused by the majority of identified pathotypes.

Summary: Genetic diversity and interspecific hybridizations are crucial in crop genetic improvement, with microsatellite markers being commonly used. This study examined the genetic diversity of 23 cashew germplasm accessions and investigated the true hybridity of interspecific hybrids of cashew and its relative. Eight out of 21 CSSRs showed polymorphism in 10 accessions, and dendrogram analysis grouped the accessions irrespective of geographic region. Three CSSR markers were identified for detecting true hybridity in interspecific hybrids, useful for evolutionary studies.

Summary: This study surveyed wheat growing areas in Northeast India, Nepal, Bhutan, and Bangladesh and identified five new pathotypes of Puccinia triticina. These pathotypes exhibited diverse virulence on leaf rust resistance genes, with some Indian wheat cultivars' resistance genes being ineffective against the new pathotypes. In contrast, other resistance genes were effective against these pathotypes. Based on SSR markers, these pathotypes were distinct and could be categorized into two groups.

Summary: This study investigated the genetic diversity and evolutionary patterns of Puccinia graminis f. sp. tritici (Pgt) pathotypes causing stem rust in wheat. Results showed significant genetic diversity among the pathotypes, which may be attributed to their long-distance dispersal ability and gene flow. These findings are important for the development of strategies for stem rust resistance breeding.

Summary: Cashew is the third most important edible tree nut in the global market, and the cashew nutshell contains cashew nutshell liquid (CNSL). A rare CNSL free mutant was observed in the germplasm, and this study aimed to understand the morphological and biochemical differences between the mutant and the normal CNSL containing genotype. The mutant showed significant differences in leaf shape, dimensions, sex ratio, yield-related traits, and biochemical composition compared to the normal genotype, making it a unique genetic material for studying the CNSL biosynthetic pathway.

Summary: Cashew, introduced to India from Brazil by Portuguese travellers, is a commercially important nut crop with nutritional value and export earnings. It belongs to the Anacardiaceae family, known for its socio-economic importance. Cashew's diversity in traits such as plant vigour, yield, nut properties, and purple coloration makes it a valuable genetic heritage for conservation and improvement programs. This study focuses on documenting the important features of the purple cashew mutant, which stands out as a novel cashew genotype.

Summary: A commercial clone of cashew, Nethra Vaman, was resequenced and its whole genome was analyzed, resulting in the identification of 420,560 SNPs and 26,987 InDels. The analysis of these genome-wide variants revealed enriched pathways related to plant hormone signal transduction and MAPK. Additionally, a set of InDel markers was developed and showed high informativeness. Cross-species amplification of these markers confirmed their effectiveness in other related species. The analysis of genetic diversity using these markers clustered the samples into three main groups.

Summary: Wheat stem rust, caused by Pgt, is a major concern for global wheat production. Understanding the characteristics, genetic diversity, origin, distribution, and evolutionary pattern of Pgt is crucial for managing newly emerging isolates through host resistance. In this study, stem rust occurrence in India and neighboring countries was monitored, Pgt isolates were collected and analyzed for virulence phenotypes and molecular genotypes. Several wheat varieties were found to have complete resistance to multiple Pgt pathotypes.
