Summary: This study constructed genetic fingerprints for individual identification of sweet potato using molecular markers and morphological markers. A genetic fingerprint database containing 1021 sweet potato germplasm resources was established, showing that Chinese sweet potato germplasm has narrow genetic variation. It was found that sweet potato germplasm resources from Peru have the richest genetic diversity, supporting the view that Peru is the center of origin and domestication of sweet potato varieties.

Summary: The study genotyped the entire sweetpotato collection housed by CIP, revealing a significant proportion of genetic identity errors that were corrected. A phylogenetic tree was constructed based on morphological descriptors, showing high redundancy in materials from Peru and Latin America. Population structure analysis identified four ancestral populations, with lower gene flow in germplasm from Peru, Ecuador, and Africa. This study marks the first report of genotyping an entire sweetpotato germplasm collection, providing important data for genetic resource conservation and utilization.

Summary: Spelt wheat is an ancient crop derived from a cross between emmer wheat and Aegilops tauschii, with origins in the Fertile Crescent and Europe. While neglected in most of Europe, a revival in interest has been driven by a desire for more natural foods. The diversity, genetic traits, and current situation of Spanish spelt are discussed in this review.

Summary: In this study, the FLS gene IbFLS1 was cloned and characterized from sweet potato. The IbFLS1 protein showed similarity with other plant FLSs and belonged to the 2-ODD superfamily. It was predominantly expressed in young leaves and localized in the nucleus and cytomembrane. Silencing the IbFLS gene resulted in a purple color change in sweet potato leaves and an increase in total anthocyanin content.

Summary: This study discovered the important physiological functions of Ipomoea batatas polysaccharides (IBPs) and determined the optimal extraction conditions. The main chain of IBP-1A was found to primarily consist of specific sugar residues. In vivo experiments on older mice showed that polysaccharide significantly increased antioxidation-related enzymes and metabolites, effectively relieving oxidative stress injury and delaying aging. Thus, this research provides a new theoretical basis for the development of IBPs as antioxidant food.

Summary: Most scholars believe that there was a pre-Columbian transpacific transfer of sweet potato plants that explains their historical importance in Indigenous New Zealand. Archaeological evidence of sweet potato cultivation by Polynesians has been found in the southern region of Otago, challenging previous assumptions about the climate there. This new information is consistent with Maori oral history and traditional knowledge about sweet potatoes in the region.

Summary: The study aimed to evaluate the genetic diversity of 215 common bean accessions, revealing wide variability in morpho-agronomic and biochemical traits. Genetic parameters showed high to intermediate heritability for most traits, and Ward's hierarchical clustering analysis grouped the accessions into six clusters. AFLP analysis also indicated significant differences among the accessions, with no correlation between genetic markers and morpho-agronomic data, highlighting the importance of both datasets in understanding accession differences.

Summary: This study investigated common bean farmers in the state of Rio de Janeiro, Brazil, finding a wide variety in the number of bean varieties managed by families due to socioeconomic, ecogeographic, and cultural factors. Climate change has affected traditional agriculture in certain regions, leading to a decrease in common bean diversity. Efforts are being made to strengthen the conservation of local germplasm and promote self-consumption cultures for food security and preservation of cultural traditions.

Summary: This study focused on the identification and characterization of Colletotrichum spp. causing anthracnose, a major disease in pepper crops in Rio de Janeiro state. Through morpho-cultural, sequencing, and genetic variability analysis, all isolates were identified as Colletotrichum scovillei. Pathogenicity testing on Capsicum baccatum revealed stage-specific responses, with higher resistance in ripe fruits, and identified potential resistance sources among tested accessions. This data could contribute to future research on the interaction between Colletotrichum scovillei and Capsicum spp., a topic that has not been extensively explored.
