Premise Of The Study: We developed simple sequence repeat (SSR) markers from expressed sequence tags (ESTs) for Callitris columellaris sensu lato (s.l.) to elucidate population genetic structure and detect outlier loci by genome scan.
Methods And Results: mRNA from an individual seedling was subjected to cDNA synthesis and then de novo pyrosequencing. Two hundred and nineteen primer pairs bordering sequence regions were designed from the obtained sequence data. In total, 52 showed polymorphism within 16 individuals representative of the species' entire range, with the number of alleles per locus and expected heterozygosity ranging from two to 10 and 0.06 to 0.84, respectively.
Conclusions: The EST-SSR markers developed in this study will be useful for evaluating the range-wide genetic structure of C. columellaris s.l. and detecting outlier loci under selection, as well as providing useful markers to investigate the conservation genetics and reproductive ecology of the species.

Biodiversity loss and degradation activities have a significant impact and devastating consequences on the ecosystem, eventually posing a major threat to many plant species, including . Deforestation and the growth of settlements are the main factors that affect the biodiversity hotspots in Vietnam such as Northwest, Northeast, North Central and Central Highlands regions. This has led to a decline of the species, so effective conservation strategies are urgently required.

RNA sequencing analysis was performed to develop 16 novel expressed sequence tag-simple sequence repeat (EST-SSR) markers to evaluate genetic variation in the near-threatened halophyte Artemisia fukudo Makino, which inhabits riversides and tidal muds affected by brackish water at high tide. In the four populations examined, the total number of alleles at each locus ranged from two to 13, with an average of 4.3.

Rye (), a cereal crop with high cold tolerance, serves as an ideal model for investigating plant cold adaptation mechanisms. Despite recent progress in identifying numerous genes and metabolic changes associated with cold tolerance, the detailed regulatory networks and coordinated interactions between metabolic pathways under low-temperature stress in rye remain unclear. In this study, we focused on the winter rye variety "Winter" and systematically explored its metabolic regulatory responses to cold stress through a combination of low-temperature treatments, phenotypic observations, antioxidant enzyme activity assays, and transcriptomic analysis.
