Summary: Despite global threats, crop wild relatives (CWRs) are a crucial source of genes for improving food security and climate change adaptation. The lack of institutions and payment mechanisms to compensate those providing CWR conservation services has hindered conservation efforts. However, a case study in Malawi demonstrates that there is high willingness to participate in conservation activities, with modest costs, indicating significant potential for community engagement in CWR conservation.

Summary: The tolerance of Triticum aestivum to mesosulfuron-methyl is higher than that of A. tauschii. The absorption and metabolism of mesosulfuron-methyl are different between the two species. The cytochrome P450 monooxygenase inhibitor, malathion, increases the sensitivity of T. aestivum to mesosulfuron-methyl.

Summary: This study investigated the genetic basis of resistance against Fusarium head blight and the mycotoxin deoxynivalenol in Aegilops tauschii, the diploid progenitor of the wheat D subgenome. By analyzing a panel of Ae. tauschii accessions, a uridine diphosphate (UDP)-glucosyltransferase (UGT) gene on chromosome 5D was identified as the causal variant for susceptibility to the mycotoxin. This UGT gene was also found to be involved in DON detoxification in hexaploid wheat. The findings highlight the conservation of this resistance mechanism in wheat and barley.

Summary: The hybridization rates between wild wheat and cultivated wheat in the central plateau of Spain have been estimated for the first time, and hybrids have been found in the populations of wild wheat species. These findings suggest that gene flow can occur between wheat species, which is essential for the risk assessment of genetically modified wheat.

Summary: Medicago L. is one of the most important forages in the world, known for its high nutritive value, palatability, and ability to improve soil fertility. However, Medicago genetic resources are at risk due to destruction, overgrazing, climate change, and drought. This study focuses on ex situ conservation activities for high priority annual Lebanese species, based on a previous gap analysis. Accessions of target species were collected, characterized, and conserved at ICARDA's Genebank. Characterization data was used to analyze phenotypic variability patterns in relation to collection site environmental conditions. Several species showed significant variability in traits related to drought tolerance, informing the proposed management plan for in situ conservation.

Summary: Future progress in wheat grain yield relies on enhancing photosynthesis capacity and biomass, and wheat wild relatives provide new genetic variation for photosynthesis traits. This study aims to quantify the variation in leaf photosynthesis traits, biomass, and grain yield in a diverse panel of germplasm under well-watered and drought conditions.

Summary: The study sequenced 242 accessions of Aegilops tauschii and identified a rare lineage contributing to the wheat D subgenome. Through association mapping, genomic regions with candidate genes for disease and pest resistance were identified and successfully transferred into wheat. Exploiting the genomic diversity of the wild progenitor allows for rapid trait discovery and functional genetic validation.

Summary: The past decade has seen significant technological advancements in genomics, specifically in DNA sequencing. Genomics has the potential to support in situ conservation of crop wild relatives (CWRs) by aiding in the prioritization of protection, identification of novel alleles for conservation, identification of potential sources of adaptive traits, and establishment of genetic reserves. It also has the potential to develop monitoring frameworks to track genetic diversity changes associated with land use and climate change. However, the widespread application of genomics in conservation is hindered by funding and lack of genomic expertise among conservation practitioners.

Summary: This study compared three variants of hard wheat puroindoline (MY26, GX3, and ZM1) with a soft wheat variety (CM605) to identify differentially abundant proteins using proteomic methods. A total of 6253 proteins were identified and quantified via mass spectrometry, and 208 differentially expressed proteins were found between the hard wheat and soft wheat varieties. Cluster analysis divided the proteins into six clusters, with 67 and 41 proteins being more abundant in CM605 and the hard wheat varieties, respectively. Enrichment analysis detected common GO terms, KEGG pathways, and IPR terms across all three comparisons. Additionally, 12 proteins associated with these terms or pathways were found to be differentially expressed in each comparison, including cysteine proteinase inhibitors, invertases, low-molecular-weight glutenin subunits, and alpha amylase inhibitors, which may play a role in grain hardness regulation. The candidate genes identified in this study may contribute to future analyses of the regulatory mechanism underlying grain hardness.
