| 1 | How does ecological civilization construction affect carbon emission intensity?Evidence from Chinese provinces’panel data显示文摘Ecological civilization construction is a new concept and trend in the era of China's high-quality development.It requires the collaborative propulsion of an ecological economic civilization,ecological social civilization,and ecological environment civilization.Reducing carbon emission intensity is an important issue facing the Chinese government in the backdrop of global warming.Thus,studying the influence of ecological civilization construction on carbon emission intensity from different perspectives has important theoretical and practical significance.In this study,the influences of the three subsystems of an ecological civilization on carbon emission intensity are empirically analyzed using Chinese provincial panel data from 2004 to 2016 and a spatial Durbin model based on the STIRPAT model.First,the Moran's I of carbon emission intensity in Chinese provinces was between 0.425 and 0.473.This indicates positive spatial correlation and illustrates that the carbon emission intensity of China's provinces can influence each other.The reasons behind this correlation include close ties between neighboring provinces and similarities in natural,economic,and social characteristics.Second,the correlation coefficients of ecological economic civilization,ecological social civilization,and ecological environment civilization to carbon emission intensity are−4.743139,2.865884,and−0.3246447,respectively.This illustrates that an ecological economic civilization and ecological environment civilization can reduce carbon emission intensity,while an ecological social civilization can increase it.To reduce total carbon emission intensity,the three subsystems of ecological civilization should have a negative relationship with carbon emission intensity,so the effect of ecological social civilization on carbon emission intensity should be changed.Third,the spatial spillover effect of ecological social civilization did not pass the significance test.The correlation coefficients of spatial spillover effect to ecological economic civilization and ecological environment civilization are 2.046531 and−3.238323,respectively.Improving the ecological economic civilization can increase the carbon emission intensity of periphery provinces,while improving the ecological environment civilization can reduce it.Thus,it is necessary to enhance cooperation between periphery provinces and establish a trans-provincial cooperation mechanism for reducing carbon emissions. | Kai Liu Yameng Tao Yi Wu Chengxin Wang | 2020 | Chinese Journal of Population,Resources and Environment2020，18，2： | 3 |

| 4 | An epi-allele of SMS causes Sanming dominant genic male sterility in rice显示文摘Male sterility is an important trait in rice for hybrid rice(Oryza sativa)breeding.However,the factors involved in dominant male sterility are largely unknown.Here,we identified a gene from Sanming dominant genic male sterile rice,named Sanming dominant male sterility(SMS),and reported that an epi-allele of this locus contributes to male sterility.Segregation analysis attributed dominant male sterility to a single locus,SMS,which we characterized using a male-sterile near isogenic line(NIL)of rice cultivar 93-11.The SMS locus was heterozygous in the male-sterile 93-11 NIL,containing an epi-allele identical to that in 93-11,and an epi-allele identical to that in rice cultivar Nipponbare,which we refer to as SMS9 and SMSN,respectively.SMS9is silent and hyper-methylated,whereas SMSNis expressed and hypo-methylated in the 93-11 NIL.Overexpressing SMSNled to male sterility.Mutations in SMS rescued the male sterility of the 93-11 NIL.Interestingly,we observed the duplication of SMSN in Nipponbare,but did not observe the duplication of SMS9in 93-11.Together,these findings suggest that the reduced methylation and enhanced expression of the SMSNepi-allele in the 93-11 NIL is responsible for its role in conferring dominant male sterility. | Yachun Yang Cheng Zhang Hao Li Zeyuan Yang Zuntao Xu Dewei Tai Dahu Ni Pengcheng Wei Chengxin Yi Jianbo Yang Yong Ding | 2023 | Science China(Life Sciences)2023，66，12： | 0 |
