The genus in basal Araceae includes both thermogenic and non/slightly thermogenic species that prefer cold environments. If floral thermogenesis of contributes to cold adaptation, it would be expected that thermogenic species have a larger habitat than non/slightly thermogenic species during an ice age, leading to increased genetic diversity in the current population. To address this question, potential distribution in past environment predicted by ecological niche modeling (ENM), genetic diversity, and population structure of chloroplast and genome-wide single nucleotide polymorphisms were compared between thermogenic and non/slightly thermogenic .

Graduate School of Human and Environmental Studies Kyoto University Yoshida-nihonmatsu-cho, Sakyo-ku Kyoto 606-8501 Japan.
Article Synopsis
- A study developed EST-SSR markers for a plant in the Cyperaceae family to explore its evolutionary background, particularly in Japan's solfatara fields.
- Using RNA-Seq technology, 20 markers were created and analyzed for genetic variation in this plant and related species, revealing low genetic polymorphism due to population dynamics.
- The findings will aid future research on genetic diversity and evolutionary history in this plant and its relatives.
Premise Of The Study: Microsatellite markers were developed for the wind cave-associated shrub subsp. to conduct phylogeographic studies on the species.
Methods And Results: Based on the sequence data obtained by 454 sequencing, a total of 81 primer pairs were designed and 18 successfully amplified the microsatellite regions.
First flowering hybrid between autotrophic and mycoheterotrophic plant species: breakthrough in molecular biology of mycoheterotrophy.

Article Synopsis
- About 880 species of land plants are mycoheterotrophs, relying on fungi for carbon instead of photosynthesis.
- Shifts from autotrophy to mycoheterotrophy in plants typically involve changes like loss of leaves and roots, smaller seeds, and altered reproductive strategies, but the underlying processes are not well understood.
- Researchers created a hybrid between autotrophic Cymbidium ensifolium and mycoheterotrophic C. macrorhizon, observing variations in leaf development and root formation after five years of growth, offering insights into the evolution of mycoheterotrophy.
