| 1 | Altitudinal Variation in Digestive Tract Length in Yunnan Pond Frog (Pelophylax pleuraden)显示文摘The digestive tract plays an important role in digestion and the acquisition of food energy. Understanding the impact of abiotic environments on digestive tract morphology is especially important for evolution of digestive tract across different environments. Here, we investigated altitudinal variation in digestive tract length in the Yunnan Pond Frog(Pelophylax pleuraden) across five populations ranging from 1413 m to 1935 m a.s.l. in Ningnan County, Sichuan province in western China. Frogs were collected during the breeding season, from 1–5 June 2012. Our results revealed that females had longer digestive tract and relative digestive tract(i.e. digestive tract length / body size) lengths in comparison to males, on average, but the differences between them decreased with increasing altitude. Digestive tract and relative digestive tract lengths increased with increasing altitude suggesting that a higher proportion of indigestible materials may be consumed at high-altitude sites and result in a relative increase in digestive tract dimensions. | Shangling LOU Yanhong LI Long JIN Zhiping MI Wenchao LIU Wenbo LIAO | 2013 | Asian Herpetological Research2013，4，4： | 0 |
| 2 | Natural variation in the SVP contributes to the pleiotropic adaption of Arabidopsis thaliana across contrasted habitats显示文摘Coordinated plant adaptation involves the interplay of multiple traits driven by habitat-specific selection pressures. Pleiotropic effects, wherein genetic variants of a single gene control multiple traits, can expedite such adaptations. Until present, only a limited number of genes have been reported to exhibit pleiotropy. Here, we create a recombinant inbred line (RIL) population derived from two Arabidopsis thaliana (A. thaliana) ecotypes originating from divergent habitats. Using this RIL population, we identify an allelic variation in a MADS-box transcription factor, SHORT VEGETATIVE PHASE (SVP), which exerts a pleiotropic effect on leaf size and drought-versus-humidity tolerance. Further investigation reveals that a natural null variant of the SVP protein disrupts its normal regulatory interactions with target genes, including GRF3, CYP707A1/3, and AtBG1, leading to increased leaf size, enhanced tolerance to humid conditions, and changes in flowering time of humid conditions in A. thaliana. Remarkably, polymorphic variations in this gene have been traced back to early A. thaliana populations, providing a genetic foundation and plasticity for subsequent colonization of diverse habitats by influencing multiple traits. These findings advance our understanding of how plants rapidly adapt to changing environments by virtue of the pleiotropic effects of individual genes on multiple trait alterations. | Xiang Guo Ruyun Liang Shangling Lou Jing Hou Liyang Chen Xin Liang Xiaoqin Feng Yingjun Yao Jianquan Liu Huanhuan Liu | 2023 | Journal of Genetics and Genomics2023，50，12： | 0 |
