Summary: This study assessed the genetic variation of 17 Scots pine populations in different regions of Russia. The results showed high levels of genetic diversity in all populations. Five genetic groups were identified, corresponding to different geographical areas. The European population showed the highest genetic distinctiveness. The genetic differentiation among populations only accounted for 5% of the total variance. These findings contribute to our understanding of the genetic diversity patterns of Scots pine populations in Middle Siberia and support conservation efforts of these genetic resources.

Summary: This study evaluated the genetic resources of 19 ancient Platycladus orientalis populations in the middle reaches of the Yellow River using nine polymorphic nuclear simple sequence repeats (nSSRs). The populations showed high genetic diversity, historical gene flow, and genetic differentiation. The analysis indicated higher genetic variation within populations rather than among populations, with the populations divided into two groups based on genetic structures.

Summary: This study filled the research gap on the geographic variation and environmental adaptability of Liushan, a widely distributed tree species in southern China. The results showed strong genetic differentiation among geographic populations, and the needle traits were significantly correlated with geography and environmental factors. Geographic isolation and environmental differences were identified as the main factors shaping the morphological traits and patterns of genetic variation. Conservation measures should focus on preserving populations with rare phenotypes.

Summary: The study analyzed the mtDNA D-loop sequences of 1163 Chinese indigenous cattle to determine their maternal origin and population genetic structure, prioritizing conservation evaluations based on a population genetic model. Three maternal origins or domestication events were identified among Chinese indigenous cattle, with various levels of genetic diversity and contributions to the richness of genetic resources. The research provides a scientific basis and effective evaluation methods for the protection of genetic resources of indigenous livestock varieties.

Summary: Leopard populations on the Chinese Loess Plateau have experienced declines and are mainly scattered in fragmented habitats. Genetic analysis of faecal samples revealed moderate mitochondrial diversity and high microsatellite diversity. The Yellow River acts as a barrier, resulting in a distinct population boundary. The time of population divergence was estimated to be between 8700 and 8300 years BP. Based on these findings, it is recommended to divide the leopard population on both sides of the Yellow River into two conservation management units.

Summary: This study investigated the genetic diversity and population structure of escaped Pyrus calleryana populations in the southeastern United States. The results showed high genetic diversity, gene flow, and genetic differentiation among individuals from different collection sites. The study also revealed that the populations differentiated shortly after the introduction to the US, most likely from specimens imported from Asia. This research provides important insights into the potential threat that P. calleryana may pose to the economy, ecology, and native biodiversity in invaded areas.

Summary: This study assessed the genetic variability of Cretan sweet chestnut using SSR markers and revealed notable genetic diversity among the four cultivars, each of which was found to be multiclonal. Genetic differentiation among cultivars was relatively low but significant, and several synonymy groups were identified. Clustering analysis showed two main clusters corresponding to Rogdiani and Katharokastania cultivars.

Summary: This study investigated the genetic diversity and structure of wild and cultivated populations of Paris polyphylla var. yunnanensis using cpDNA trnL-trnF sequences. The cultivated populations showed higher haplotype richness and genetic diversity compared to the wild populations, which may be attributed to their mixed provenance. There was a geographical and genetic connection between the wild populations, while no significant genetic differentiation was observed between the wild and cultivated populations.

Summary: Slovenia has a long tradition of plum cultivation and use due to its specific climatic, soil, geographic, and historical conditions. This study used SSR and cpDNA markers to evaluate the genetic diversity of Prunus species, investigate the involvement of certain species in P. domestica origin, and study the genetic relationships and variability among typical P. domestica accessions in Slovenia. The results provide valuable insights into the plum germplasm diversity, conservation process, and enrichment of plant genetic resources.

Summary: This study provides the first assessment of the genetic structure of green turtle populations within French Polynesia and fills an essential data gap regarding the genetic diversity of the species and its connectivity to other feeding grounds in the Pacific Ocean. The French Polynesian populations appear to be important contributors to the overall genetic diversity of the species, isolated from other Pacific populations, thus making them essential within the Pacific region. These results have important implications for the conservation of the species at both local and regional scales.

Summary: This study examined the genetic differences among D. gallaeformans populations from different locations and host species and found that the species is monophyletic and has three major clades, which were mostly consistent with geographic location but not with host species. The study suggests that D. gallaeformans does not exhibit host-species specialization.

Summary: This study analyzed the genetic variability, inbreeding, and population structure of the Tunisian-North African dairy sheep breed, the Sicilo-Sarde. The results showed that the breed has a high level of genetic diversity and has not undergone a population bottleneck. The study also found that the introduction of new genes through breeding programs has positively impacted the genetic diversity of the breed.

Summary: Ethylene induces anthocyanin biosynthesis in most fruits, but inhibits it in pears. The transcription factor PpERF105 activated the expression of PpMYB140, which then inhibited the anthocyanin biosynthesis in pears. The competition between PpMYB140 and PpMYB114 led to the formation of a complex that further inhibited anthocyanin biosynthesis.

Summary: This review focuses on the molecular regulation of endodormancy induction, maintenance, and release in floral buds of deciduous fruit trees, as well as recent advances in quantitative trait loci analysis of chilling requirements. The discussion includes phytohormones, epigenetic regulation, and the molecular network controlling endodormancy, centered on SVP and DAM genes. Understanding endodormancy can help in creating new cultivars with different chilling requirements.

Summary: Dormancy-associated MADS-box (DAM) genes play a crucial role in regulating the endodormancy cycle in rosaceous plants. A high-quality genome assembly for the 'Cuiguan' pear (Pyrus pyrifolia) was constructed using PacBio and Hi-C technologies, revealing the differential expression of pear DAM genes and their repressive effects on bud break. Novel genes potentially involved in endodormancy release regulation were identified through RNA and chromatin immunoprecipitation sequencing analyses.

Summary: This study investigates the effect of defoliation on pear trees and finds that defoliation-induced auxin efflux from buds accelerates bud paradormancy release, leading to out-of-season flowering. The findings are important for understanding the mechanism of bud dormancy and developing methods to inhibit early defoliation-induced out-of-season flowering.

Summary: This study identified and functionally characterized a light-inducing WRKY transcription factor, PpWRKY44, in pear. PpWRKY44 promotes anthocyanin accumulation in pear and regulates its transcription by binding to the PpMYB10 promoter. These results reveal the mechanism of PpWRKY44 in the transcriptional regulation of fruit peel coloration in red pears.

Summary: Pyrus species are widespread throughout the Eurasian continent and are divided into occidental and oriental pears. Elucidating phylogenetic relationships in Pyrus is challenging due to lack of distinguishing characters and frequent hybridization. Recent studies suggest that reticulate evolution caused by hybridization is a major evolutionary strategy in Pyrus species.
