As one of the most important crops in the world,rice(Oryza sativa)is a model plant for metabolome *** many studies have focused on the analysis of specific tissues,the changes in metab-olite abundance across the entire life cycle have not yet been *** this study,combining both tar-geted and nontargeted metabolite profiling methods,a total of 825 annotated metabolites were quantified in rice samples from different tissues covering the entire life *** contents of metabolites in different tissues of rice were significantly different,with various metabolites accumulating in the plumule and radicle during seed *** these data with transcriptome data obtained from the same time period,we constructed the Rice Metabolic Regulation *** metabolites and co-expressed genes were further divided into 12 clusters according to their accumulation patterns,with members within each cluster displaying a uniform and clear pattern of abundance across *** this dataset,we established a comprehensive metabolic profile of the rice life cycle and used two independent strategies to identify novel transcription factors-namely the use of known regulatory genes as bait to screen for new networks underlying lignin metabolism and the unbiased identification of new glycerophospholipid metabolism regulators on the basis of tissue *** study thus demonstrates how guilt-by-association analysis of metabolome and transcriptome data spanning the entire life cycle in cereal crops provides novel resources and tools to aid in understanding the mechanisms underlying important agro-nomic traits.

Common Cuckoos(Cuculus canorus)dependent on parental care for post-hatching demonstrate an intriguing ability to modify their begging vocalizations to ensure maximum care and resources from their interspecific foster ***,we compared begging calls of the Common Cuckoo nestlings fed by four host species,the Grey Bushchat(Saxicola ferreus),Siberian Stonechat(Saxicola maurus),Daurian Redstart(Phoenicurus auroreus),and Oriental Magpie-robin(Copsychus saularis).Results showed that begging calls of the stonechat-,redstart-,and robin-cuckoo resemble those of host species'nestlings in various aspects like low frequency,high frequency,frequency bandwidth and peak frequency,while the bushchat-cuckoo chicks'begging calls were only comparable to their host species in terms of how long they lasted and their peak *** addition,cuckoo nestlings raised in different host nests displayed significant variations in their begging calls in low and peak *** study suggests that cuckoo nestlings do not mimic host species nestlings'begging calls throughout the nestling period,but may tune their begging calls according to host species,while begging calls vary with cuckoo and host species nestlings'*** research should study the parents'reactions to these calls in different host species for a better understanding of the mechanisms underlying such adaptations.

PVDF ultrafiltration membranes of controlled performance via blending PVDF-g-PEGMA copolymer synthesized under different reaction times

Frontiers of Environmental science & Engineering 2018年第2期12卷 29-40页

作者： Shuai Wang Tong Li Chen Chen Baicang Liu John C. Crittenden College of Architecture and Environment Sichuan University Chengdu 610207 China Institute of New Energy and Low Carbon Technology Sichuan University Chengdu 610207 China Research Center for Eco-Environmental sciences Chinese Academy of Sciences Beijing 100085 China Litree Purifying Technology Co. Ltd Haikou 571126 China Brook Byers Institute for Sustainable Systems School of Civil and Environmental Engineering Georgia Institute of Technology Atlanta GA 30332 USA

Polyvinylidene fluoride grafted with poly（ethylene glycol） methyl ether methacrylate （PVDF-g- PEGMA） was synthesized using atomic transfer radical polymerization （ATRP） at different reaction times （9 h, 19 h, and 29 h）. The corresponding conversion rates were 10%, 20% and 30%, respectively. PVDF was blended with the copolymer mixtnre containing PVDF-g-PEGMA, solvent and residual PEGMA under different reaction times. In this study, we explored the effect of the copolymer mixture additives with different synthesis times on cast membrane performance. Increasing the reaction time of PVDF-g-PEGMA causes more PVDF-g-PEGMA and less residual PEGMA to be found in the casting solution. Incremental PVDF-g-PEGMA can dramatically increase the viscosity of the casting solution. An overly high viscosity led to a delayed phase inversion, thus hindering PEGMA segments in PVDF- g-PEGMA from migrating to the membrane surface. However, more residual PEGMA contributed to helping rnore PEGMA segments migrate to the membrane surface. The pure water fluxes of the blended membrane with reaction times of 9 h, 19 h, and 29 h are 5445 L. m 2.h I 1068 L- m 2.h land 1179 L.m 2.h I respectively, at 0.07 MPa. Delayed phase inversion can form smaller surface pore size distributions, thus decreasing the water flux for the membranes with PVDF-g-PEGMA at 19 h and 29 h. Therefore, we can control the membrane pore size distribution by decreasing the reaction time of PVDF-g-PEGMA to obtain a better flux performance. The membrane with PVDF-g-PEGMA at 19 h exhibits the best foulant rejection and cleaning recovery due to its narrow pore size distribution and high surface oxygen content.
