Wild emmer wheat is an excellent reservoir of genetic variability that can be utilized to improve cultivated wheat to address the challenges of the expanding world population and climate change. Bearing this in mind, we have collected a panel of 263 wild emmer wheat (WEW) genotypes across the Fertile Crescent. The genotypes were grown in different locations and phenotyped for heading date. Genome-wide association mapping (GWAS) was carried out, and 16 SNPs were associated with the heading date. As the flowering time is controlled by photoperiod and vernalization, we sequenced the gene, the most important of the vernalization response genes, to discover new alleles. Unlike most earlier attempts, which characterized known alleles according to a partial promoter or intron sequences, we obtained full-length sequences of and genes in a panel of 95 wild emmer wheat from the Fertile Crescent and uncovered a significant sequence variation. Phylogenetic analysis of and haplotypes revealed their evolutionary relationships and geographic distribution in the Fertile Crescent region. The newly described alleles represent an attractive resource for durum and bread wheat improvement programs.

Article Synopsis
- Researchers explored the role of m6A-related genes in wild emmer wheat, identifying 64 candidates responsible for RNA modification, including writers, erasers, and readers.
- The study revealed that gene duplication and polyploidization significantly contributed to the expansion of these genes, with promoter analysis showing links to stress and hormonal response elements.
- A specific focus on the gene TdFIP37 highlighted its crucial role in regulating salt tolerance, with loss-function mutants demonstrating increased sensitivity to salt stress, linking it to the MAPK signaling pathway.

Article Synopsis
- * A wild emmer introgression line, BAd7-209, showed greater drought resistance than the drought-resistant wheat variety Zhongmai 175, with transcriptome analysis revealing significant gene expression changes in response to drought.
- * The study identified TdNACB as a key transcription factor that enhances drought resistance in crops like rice by increasing proline content and boosting enzyme activity related to reactive oxygen species scavenging, providing potential candidate genes for improving wheat drought resistance.
Plant cultivation and diversity at the early neolithic settlement in Biskupice in Poland.

The emergence of the Linear Pottery Culture (LBK) during the Neolithic period within Polish territory 5400-4900 BC, introduced plant cultivation, yet the definitive list of cultivated species remains debated. This study examines plant assemblages (fruits, seeds, pollen, and spores) from the LBK settlement in Biskupice, southern Poland, aiming to identify cultivated and wild species used during the development of the first stable settlements in the Carpathian Foothills. Due to extensive sampling, Biskupice yielded over 11,000 macroscopic plant specimens, enabling detailed analysis of plant diversity, distribution, and implications for agrarian and dietary practices.

As important secondary metabolites in plants, anthocyanins not only contribute to colored plants organs, but also provide protections against various biotic and abiotic stresses. In this study, a MYB transcription factor gene TdRCA1 from wild emmer wheat regulating anthocyanin biosynthesis in wheat coleoptile was identified on the short arm of chromosome 7A in common wheat genetic background. The TdRCA1 overexpression lines showed colored callus, coleoptile, auricle and stem nodes, as well as up regulation of six anthocyanin-related structural genes.
