Summary: Root hairs are extensions of root epidermal cells that increase in length and density under low phosphorus availability. This study explores the genes involved in root hair development and response to low phosphorus in chickpea, an important leguminous crop. The findings reveal that genes related to root hair initiation and cellular differentiation are upregulated, and genes involved in cell wall synthesis, cytoskeleton/vesicle transport, and ethylene biosynthesis are also upregulated in root hairs. In addition, genes related to low phosphorus responses, such as lipid and/or pectin P remobilization and acid phosphatases, are induced in root hairs. The study also highlights the preferential enrichment of processes involved in symbiotic interactions in root hairs. Overall, root hairs exhibit a multifaceted response to low phosphorus, involving molecular changes in epidermal cell differentiation and root hair initiation, as well as tip growth and various low phosphorus responses in elongated root hairs.

Summary: This study investigates the evolutionary history and domestication process of lentils using genotyping-by-sequencing and archaeological information, identifying 87,647 SNPs and confirming the phylogeny and domestication of lentils. Two domesticated gene pools of lentils emerged in Southwest Asia region, with some alleles related to domestication and climate adaptation identified. The results have implications for plant domestication, genetic diversity distribution, and gene targeting in breeding programs.

Summary: Based on the research results, a decrease in water supply negatively affects the growth and productivity of chickpeas, and white chickpeas and black chickpeas have different biomass and water allocation strategies under low water supply. These findings are important in guiding strategies to improve the productivity and nutritional profile of chickpea crops under water-limited conditions.

Summary: This article investigates a type of epiphytic cactus in Mesoamerica that is considered as a promising but underutilized crop. The study compares transcriptome profiles of wild and cultivated plants, focusing on the differences related to drought stress. The findings suggest that variations in the management of the two cultivated varieties may contribute to the observed differences.

Summary: Chickpea, also known as Bengal gram or Garbanzo bean, is facing productivity crisis worldwide due to various stresses. The genetic diversity of cultivated chickpea is limited, hindering the development of stress-resilient cultivars. However, the wild relatives of chickpea offer hope for improving the cultivated gene pool. This review summarizes efforts to understand the origins and evolution of chickpea's gene pool, as well as the limitations in utilizing wild relatives for crop improvement. The review highlights the importance of genomics in uncovering trait-specific diversity and domestication patterns of chickpea, and the potential for using this knowledge to enhance crop improvement.

Summary: The characterization and preservation of genetic variation in crops is crucial for breeding in changing climates and markets. While the use of SNPs has become routine, other forms of variation, such as CNVs, are often overlooked. This study used SNPs and CNVs to analyze the genetic variation and population structure of lentil, a significant cold-season legume. The results highlighted the importance of CNVs in understanding evolutionary adaptation and identifying candidate genes.

Summary: Research on Brassica oleracea has identified its closest living wild relative and supported an origin of cultivation in the Eastern Mediterranean region. Additionally, the study found several feral lineages, indicating that cultivated plants of this species can revert to a wild-like state with relative ease.

Summary: Domesticated sorghum possesses the ability to maintain hazardous concentrations of cyanogenic glucosides in its leaves, a trait that is absent in wild sorghum taxa from other subgenera. This ability may have evolved during the divergence of the subgenus Eusorghum from other Sorghum subgenera, rather than during the speciation or domestication of S. bicolor.

Summary: Crop domestication is a co-evolutionary process that has made plants and animals heavily dependent on human interventions. Grain legumes have played a significant role in the development of agriculture, but their domestication process is not as well understood as cereals. Understanding the domestication of legumes can help in breeding programs by utilizing the genetic variation present in wild relatives. Whole genome sequencing and omics-level data have improved our ability to study the genetic changes accompanying these processes. A detailed domestication history of grain legumes can help in developing modern cultivars with improved traits.

Summary: Crop breeders face the challenge of increasing production while mitigating climate change impacts. Taxonomic and genetic diversity, mainly found in crop wild relatives (CWR), are crucial for addressing these challenges but are currently limited. This paper proposes enhancing in situ conservation of CWR to provide breeders with critical resources to promote global food security.

Summary: This study investigates the control of flowering time in chickpea (Cicer arietinum) through transcriptome analysis. The researchers identify and analyze differentially expressed genes in different chickpea cultivars and wild species, showing that the differences in gene expression are vernalization-dependent. They also highlight the role of the FTa3 gene in the vernalization response of cultivated chickpea. This research contributes to our understanding of flowering time control in chickpea and provides potential genetic strategies for improvement of this important agronomic trait.

Summary: This study compared the seed coat anatomy and histochemistry of four pea genotypes and found clear differences at different developmental stages. The establishment of seed coat thickness early in development was primarily governed by macrosclereid cells, and polyanionic staining indicated non-homogeneity, particularly in the hilum, micropyle, and upper parts of the macrosclereids. High peroxidase activity was detected in both wild and cultivated genotypes, peaking prior to desiccation. This detailed analysis of seed coat anatomy is crucial for molecular or biochemical studies and useful for comparing different genotypes and treatments in economically important legume crops.
