different proteome profiles Between male and female populus cathayana exposed to <B>UVB> B Radiation
Frontiers in Plant Science, 2017Co-Authors: Yunxiang Zhang, Lihua Feng, Hao Jiang, Yuanbin Zhang, Sheng ZhangAbstract:With increasing altitude, solar <B>UVB>-B Radiation is enhanced. Based on the phenomenon of male-Biased sex ratio of Populus cathayana Rehder in high altitude alpine area, we hypothesized that males have a faster and more sophisticated responsive mechanism to high <B>UVB>-B Radiation than that of females. Our previous studies have shown sexually different responses to high <B>UVB>-B Radiation were existed in P. cathayana at the morphological, physiological, and transcriptomic levels. However, the responses at the proteomic level remain unclear. In this study, an isoBaric tag for relative and aBsolute quantification (iTRAQ)-Based quantitative proteome analysis was performed in P. cathayana females and males. A total of 2,405 proteins were identified, with 331 proteins defined as differentially expressed proteins (DEPs). Among of these, 79 and 138 DEPs were decreased and 47 and 107 DEPs were increased under high solar <B>UVB>-B Radiation in females and males, respectively. A Bioinformatics analysis categorized the common responsive proteins in the sexes as related to carBohydrate and energy metaBolism, translation/transcription/post-transcriptional modification, photosynthesis, and redox reactions. The responsive proteins that showed differences in sex were mainly those involved in amino acid metaBolism, stress response, and translation/transcription/post-transcriptional modification. This study provides proteomic profiles that poplars responding to solar <B>UVB>-B Radiation, and it also provides new insights into differentially sex-related responses to <B>UVB>-B Radiation.

<B>UVB> B Radiation induces root Bending through the flavonoid mediated auxin pathway in araBidopsis
Frontiers in Plant Science, 2018Co-Authors: Jinpeng Wan, Ping Zhang, Ruling Wang, Liangliang Sun, Wenying Wang, Huakun ZhouAbstract:Ultraviolet (<B>UVB>)-B Radiation-induced root Bending has Been reported; however, the underlying mechanisms largely remain unclear. Here, we investigate whether and how auxin and flavonoids are involved in <B>UVB>-B Radiation-induced root Bending in AraBidopsis using physiological, pharmacological, and genetic approaches. <B>UVB>-B Radiation modulated the direction of root growth By decreasing IAA Biosynthesis and affecting auxin distriBution in the root tips, where reduced auxin accumulation and asymmetric auxin distriBution were oBserved. <B>UVB>-B Radiation increased the distriBution of auxin on the nonradiated side of the root tips, promoting growth and causing root Bending. Further analysis indicated that <B>UVB>-B induced an asymmetric accumulation of flavonoids; this pathway is involved in modulating the accumulation and asymmetric distriBution of auxin in root tips and the suBsequent redirection of root growth By altering the distriBution of auxin carriers in response to <B>UVB>-B Radiation. Taken together, our results indicate that <B>UVB>-B Radiation-induced root Bending occurred through a flavonoid-mediated phototropic response to <B>UVB>-B Radiation.

Deesterification damage of Phaeodactylum tricornutum caused By <B>UVB>-B Radiation
Marine Fisheries Research, 2002Co-Authors: Liu ChengAbstract:<B>UVB> B Radiation could heavily inhiBit the growth of Phaeodactylum tricornutum. Its 96 h EC 50 was 1.91J/m 2. Further results showed that <B>UVB> B Radiation enhancement resulted in increment of active oxygen content in algal cells, and deesterification damage mediated By active oxygens in Phaeodactylum tricornutum was appeared.

Studies on the damage of <B>UVB>-B Radiation to DNA of Phaeodactylum tricornutum
Marine Fisheries Research, 2002Co-Authors: Liu ChengAbstract:The damage of <B>UVB> B Radiation to DNA of Phaeodactylum tricornutum was studied By using ecotoxicological and Biochemical methods. The results showed that lower dosage of <B>UVB> B Radiation could stimulate the growth of P.tricornutu ,while higher dosage of <B>UVB> B Radiation could inhiBit its growth. The DNA damage of algal cells increased with the increased dosage of <B>UVB> B Radiation. The DNA damage was recovered oBviously after <B>UVB> B Radiation was removed. All these showed that the DNA damage could indicate the damage degree of marine microalgae resulted from <B>UVB> B Radiation.

The role of <B>UVB>-B Radiation and precipitation on straw decomposition and topsoil C turnover
Soil Biology and Biochemistry, 2014Co-Authors: Shurong Liu, Gaochao Cai, Shan Lin, Jinsong ZhaoAbstract:ABstract In arid and semi-arid area, ultraviolet-B (<B>UVB>-B) Radiation plays a mainly positive role in litter decomposition. In suBtropical area, however, the role of <B>UVB>-B Radiation remains uncertain due to the interference of precipitation. To evaluate the potential contriBution of precipitation to the role of <B>UVB>-B Radiation, we exposed 84 Bags of rice straw to amBient and reduced <B>UVB>-B Radiation, with and without water addition after each precipitation event, on the roof of a Building at Huazhong Agricultural University (Wuhan, China). Additionally, the indirect effects of <B>UVB>-B Radiation on soil dissolved organic carBon (DOC) were investigated By placing 70-g soil samples Beneath 5-g straw Bags with precipitation treatments. Mass loss, DOC and water extractaBle phenols (WEP) were monitored over 228 days. SuBsequently, microBial facilitation was studied, By incuBating straw and soil samples exposed for the longest period (228 days) in the laBoratory at 25 °C, and By afterwards analyzing their CO2–C emission. Our results demonstrated that <B>UVB>-B Radiation did not significantly affect straw mass loss, But induced an increase in straw DOC, WEP and CO2–C emission By 20.6%, 10.7% and 20.4%, respectively, under dry conditions. Whereas, comBined with precipitation, the effects of <B>UVB>-B Radiation on straw DOC, WEP and CO2–C emission were negligiBle. Only a small decrease in soil DOC (9.9%) and CO2–C (4.0%) was oBserved. Furthermore, <B>UVB>-B Radiation interacted significantly with precipitation during straw decomposition. These results indicate that for dry conditions <B>UVB>-B Radiation accelerates straw decomposition By increasing DOC content. For wet conditions, however, the effects of <B>UVB>-B Radiation on straw decomposition are Balanced out and even negative on topsoil C turnover.
