Summary: This study aimed to analyze common bean cultivars in Turkey for resistance genes to anthracnose caused by Colletotrichum lindemuthianum. Different molecular markers were used to identify various resistance genes in the cultivars, and some cultivars showed high resistance to the pathogen isolates. These resistant cultivars can be valuable sources for breeding programs aiming to enhance resistance to anthracnose disease in common beans.

Summary: This study aimed to develop publicly available protocols for DNA extraction and KASP assaying using a liquid handling robot (LHR) to expedite genetic screening for bean anthracnose. The results suggest that LHRs can reduce the active human time required for screening and facilitate higher throughput use of genetic marker screening tools, although more accurate markers are still needed.

Summary: In this study, Tomato leaf curl Palampur virus (ToLCPalV) was detected in the west of Iran for the first time. Dadfar, Ghafar, Ofogh, and Naz cultivars of common bean were found to be resistant to ToLCPalV infection. The activities of peroxidase, polyphenol oxidase, and phenylalanine ammonia-lyase enzymes were higher in resistant cultivars, suggesting their role as resistance factors.

Summary: This study aimed to determine the genetic diversity among Brazilian carioca common bean cultivars for traits related to nitrogen use efficiency and identify potential parents for breeding programs. The experiments showed wide genetic variability for NUsE-related traits under different nitrogen conditions, with the possibility of indirect selection through shoot dry biomass. The most low-N-tolerant cultivars were not necessarily the most responsive to NUsE, indicating different mechanisms controlling these traits.

Summary: Common bean is grown in diverse pedoclimatic conditions with variations in management practices and cultivars. Simulation models can be a useful tool for optimizing irrigation management. This study used the CSM-CROPGRO-Dry bean model to determine the optimal irrigation levels for different sowing dates and cultivars. The results showed that regulated water deficit irrigation can be implemented without significantly reducing bean yields if early sowing is done within the winter season. The model also highlighted the importance of avoiding sowing dates that coincide with periods of low solar radiation for achieving higher yields.

Summary: Bean authentication using PLS-DA with digital images allows for the nondestructive discrimination of different Phaseolus vulgaris L. cultivars. Building three separate PLS1-DA models for two cultivars each was found to be more effective than a simultaneous treatment for all three cultivars (PLS2-DA). This method can be applied for bean quality control and cultivar authenticity in commerce.

Summary: Dry beans are an important pulse consumed worldwide, with phenolic compounds in beans with colored coats found to be more efficient antioxidants. Total phenolic content can be considered as an indicator of antioxidant activity. These results provide a foundation for selecting dry beans with greater functional and nutritional interest for direct consumption, food formulations, or future breeding programs.

Summary: This study identified differentially expressed genes (DEGs) related to response to anthracnose in common bean crops. The resistant genotype exhibited enriched GO terms associated with stimulus response, hormone signaling, cellular component organization, phosphorylation activities, and transcriptional regulation. The region containing the Co-2 cluster, a resistance gene, was identified and found to contain 23 DEGs, including 8 typical R genes. The structural changes observed in this region were used to design potential DNA markers for breeding purposes.

Summary: A study reveals that the first common bean cultigens introduced in Europe after 1492 were of Andean origin and that hybridization, selection, and recombination played a role in shaping the genomic diversity of the European common bean. The study also highlights the adaptive introgression and selection of genes related to flowering and environmental adaptation in the process of disseminating this tropical crop to temperate Europe.

Summary: Bread wheat has traditionally been selected for white flour, resulting in low grain carotenoid content. In contrast, high yellow pigment content is desired for durum wheat used in pasta production. This study transferred carotenoid-related genes from durum to bread wheat and successfully developed bread wheat pre-breeding lines with enhanced grain carotenoid content. These lines have the potential to become new bread wheat varieties or be used in breeding programs.

Summary: A study characterized 54 snap bean lines grown under organic farming for various traits and grouped them based on pod cross-section shape and color. Significant differences were observed among lines and groups for all the investigated traits. The phenolic composition and antioxidant activity of selected lines with contrasting firmness and belonging to different color groups were investigated, revealing a general decrease in some compounds after cooking. The study provides useful information for designing specific varieties for different markets and purposes.

Summary: The content of yellow pigment in durum wheat grain is mainly due to the accumulation of carotenoids, which gives pasta its bright yellow color preferred by consumers. Carotenoids are also important nutrients with essential biological functions for human health. The identification of the XAT-7A1 gene responsible for carotenoid esterification in durum wheat is a necessary step for breeding programs to enhance carotenoid levels in wheat varieties. The focus should be on the Type 1 XAT-7A1 haplotype, which has been associated with high levels of carotenoid ester production.

Summary: This study investigated the genetic diversity and possible genetic erosion in the seed collections of the Fabada market class over the past 30 years. The findings revealed that genetic diversity was maintained but genetic erosion occurred. Redundant and mistakenly classified lines were identified within the Fabada market class. Furthermore, genetic erosion was observed between the conserved seed population and the currently cultivated population, and this erosion was not attributed to the spread of modern cultivars.
