Summary: This study used genomic in situ hybridization (GISH) to visualize the introgression of genetic material from the B subgenome of a wild potato species, S. stoloniferum, into backcross hybrids. The results showed that the B subgenome was inherited as single chromosomes or recombinant chromosomes in the backcross generations. Rare A/B homeologous chromosome pairing was detected in all hybrids.

Summary: Dissecting the genetic architecture of quantitative traits in autotetraploid species poses methodological challenges, but is essential for breeding globally important crops. A novel likelihood-based QTL mapping method developed for autotetraploids outperforms existing methods in statistical power and accuracy, as demonstrated through simulation studies and analysis of potato datasets.

Summary: Long-distance signaling molecules, such as TCTP mRNA, are important in plant development and responses to the environment. TCTP regulates cell cycle progression, programmed cell death, and has various other functions. In this study, the role of TCTP in tuber development and vegetative propagation was investigated by analyzing its overexpression in a solanaceous plant model. The results showed that the overexpression of StTCTP led to larger sprouts and early tuber formation, indicating its involvement in vegetative propagation and asexual reproduction.

Summary: This study analyzed the genomic composition and meiotic pairing in interspecific somatic hybrids and their backcrossing derivatives using genomic in situ hybridization (GISH). The results showed partial loss and complete elimination of alien chromosomes in the backcross generations. The study also identified hybrids with complete integration of wild chromosomes into the potato genome and hybrids with intergenomic recombinant chromosomes through GISH.

Summary: Freezing severely affects potato production. Understanding the pathways and metabolites that regulate potato's freezing tolerance is beneficial for cultivation and breeding purposes. In this study, it was found that Solanum acaule is more freezing tolerant compared to S. tuberosum. Through RNA-seq and metabolomics analysis, it was discovered that S. acaule activated different genes and enriched certain pathways, such as the hormone signaling pathway involving salicylic acid. Further analysis showed that the content of salicylic acid increased in S. acaule after exposure to cold conditions, leading to improved freezing tolerance. Additionally, the application of salicylic acid to potato enhanced freezing tolerance and increased the expression of HSFC1.

Summary: In this study, 144 tetraploid potato genotypes were evaluated to investigate the variation of physiological and agronomic traits under control and water stress conditions. A total of 18 SNP markers significantly associated with these traits were identified, providing insights into the mechanisms of potato tolerance to water stress and potential markers for marker-assisted selection programs.

Summary: The comparative structural and functional analysis of chitin-binding lectins from S. tuberosum and S. lycopersicum revealed high percentages of proline residues and differences in binding affinity towards different chitin oligomers. The study showed that the binding of glycans significantly improved the structural stability of STL and SLL. These findings provide insights into the potential therapeutic properties of STL and SLL, laying the foundation for further experimental studies.

Summary: This study reports the chromosome-scale genome assemblies of the diploid progenitors of Poa annua, as well as the biased movement of retrotransposons and large-scale chromosomal rearrangements in the allotetraploid P. annua. The divergent evolutions of the diploid progenitors play a central role in conferring P. annua's phenotypic plasticity.

Summary: This study assessed the distribution of long terminal repeat retrotransposons (LTR-RTs) in four cucurbit species and found that they played a significant role in the diversification of cucurbit species, especially in genome size variation. The study also revealed that LTR-RTs had an impact on genes related to dietary fiber synthesis and increased our understanding of genome evolution and trait characterization in cucurbits.

Summary: The study focused on environmental modulation of DNA methylation in wild potatoes, specifically in an arid Andean region in Argentina. It was found that environmentally induced epigenetic variation played a role in phenotypic plasticity, with rapid epigenomic remodeling observed in response to growing seasons and altitude differences. These results have implications for understanding the ecological diversity and populations persistence of wild potatoes.

Summary: By studying three cv. Malbec clones cultivated in two vineyards with contrasting environmental conditions, it was demonstrated that DNA methylation plays a crucial role in phenotypic plasticity and that epigenetic modulation is dependent on the specific clone. Environmental signals can induce epigenetic changes that alter gene expression and phenotype. DNA methylation has been identified as a key mechanism underlying phenotypic variability in grapevines, with clone-dependent effects observed.

Epigenetic changes induced by NTP treatments were observed, with both demethylation and methylation changes at specific loci potentially contributing to the phenotypic differences observed.

Summary: Within the Solanaceae family, the tribe Hyoscyameae consists of eight genera distributed across Eurasia. Recent research using complete chloroplast genomes has helped resolve some phylogenetic relationships within the tribe, but many remain unresolved. Phylogenetic analyses confirm Atropa as an early-diverging lineage, with well-supported relationships between Przewalskia, Physochlaina, and Scopolia in one clade, and Hyoscyamus and Anisodus in another. The paraphyletic relationship between Scopolia and Physochlaina is of note, and new insights have been gained into the evolution of the mitochondrial cox1 intron.

Summary: DNA methylation is a key epigenetic mark that plays a role in gene silencing and transposable elements' (TEs) repression. It varies significantly throughout the plant life cycle, but is efficiently reinforced during reproduction to maintain stable TE silencing. Plant reproduction can occur through different modes, including asexual propagation, which bypasses critical reinforcement steps. This review summarizes recent progress in understanding DNA methylation inheritance in sexual and asexual plants. It suggests that the methylomes of asexual seeds should resemble those of sexual counterparts, whereas clonally propagated plants are expected to have hypomethylated genomes with frequent stochastic epigenetic changes. The use of nonmodel organisms holds promise for advancing our knowledge of epigenetic inheritance in plants.

Summary: DNA methylation in plant genomes can provide genealogical information at short time scales, but its reliability at micro-evolutionary time scales is unclear due to meta-stability and environmental effects. In a study of common dandelion, differentially methylated cytosines (DMCs) were induced by light treatment, with genetic divergence between accessions correlating strongly with overall methylation profiles. However, environmental effects may partly dilute the genealogical signal in CG context. Methylation information can be used to reconstruct micro-evolutionary genealogy in plants lacking genetic variation.
