| 1 | Blue light is more essential than red light for maintaining the activities of photosystem Ⅱ and Ⅰ and photosynthetic electron transport capacity in cucumber leaves显示文摘Blue and red lights differently regulate leaf photosynthesis. Previous studies indicated that plants under blue light generally exhibit better photosynthetic characteristics than those under red light. However, the regulation mechanism of related photosynthesis characteristics remains largely unclear. Here, four light qualities treatments(300 μmol m–2 s–1) including white fluorescent light(FL), blue monochromatic light(B, 440 nm), red monochromatic light(R, 660 nm), and a combination of red and blue light(RB, R:B=8:1) were carried out to investigate their effects on the activity of photosystem II(PSII) and photosystem I(PSI), and photosynthetic electron transport capacity in the leaves of cucumber(Cucumis sativus L.) seedlings. The results showed that compared to the FL treatment, the R treatment significantly limited electron transport rate in PSII(ETRII) and in PSI(ETRI) by 79.4 and 66.3%, respectively, increased non-light induced non-photochemical quenching in PSII(ΦNO) and limitation of donor side in PSI(ΦND) and reduced most JIP-test parameters, suggesting that the R treatment induced suboptimal activity of photosystems and inhibited electron transport from PSII donor side up to PSI. However, these suppressions were effectively alleviated by blue light addition(RB). Compared with the R treatment, the RB treatment significantly increased ETRII and ETRI by 176.9 and 127.0%, respectively, promoted photosystems activity and enhanced linear electron transport by elevating electron transport from QA to PSI. The B treatment plants exhibited normal photosystems activity and photosynthetic electron transport capacity similar to that of the FL treatment. It was concluded that blue light is more essential than red light for normal photosynthesis by mediating photosystems activity and photosynthetic electron transport capacity. | MIAO Yan-xiu W ANG Xiao-zhuo G AO Li-hong C HEN Qing-yun QU Mei | 2016 | Journal of Integrative Agriculture2016，15，1： | 9 |
| 2 | Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows显示文摘Known as the‘third polar region’,the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there.Previous studies of birds,animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence.The adaptive processes during the initial phase of highland adaptation remain poorly understood.We studied a human commensal,the Eurasian Tree Sparrow,which has followed human agriculture to the Qinghai-Tibet Plateau.Despite strong phenotypic differentiation at multiple levels,in particular in muscle-related phenotypes,highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years.In a one-month acclimation experiment investigating phenotypic plasticity,we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes.Through population genetic analyses,we identified a signature of polygenic adaptation,whereby shifts in allele frequencies are spread across multiple loci,many of which are associated with muscle-related processes.Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution,shedding light on early stages of adaptive evolution to a novel environment. | Yanhua Qu Chunhai Chen Ying Xiong Huishang She Yong E Zhang Yalin Cheng Shane DuBay Dongming Li Per G P Ericson Yan Hao Hongyuan Wang Hongfeng Zhao Gang Song Hailin Zhang Ting Yang Chi Zhang Liping Liang Tianyu Wu Jinyang Zhao Qiang Gao Weiwei Zhai Fumin Lei | 2020 | National Science Review2020，7，1： | 2 |
