Promoting East-West Interaction Exclusive interview with Dr.Cao Yushu,Deputy Director of the Office of the Leading Group for Western Region Development at the State Council

Economic growth and environmental "friendliness" are the dual missions of China's grand western development. In the past eight years,China has seen the gap between eastern and western regions still widening while also taking on the arduous task of protecting nature,ecology and environment in the western region. How has western development fared in the past eight years? What difficulties and challenges are being encountered? The development of the western region poses the single greatest difficulty facing China's regional economic development,but how can we advance along a "sound and fast" development path? The establishment of economic zones in Chengdu and Chongqing,Guanzhong and North Bay has opened up new possibilities and expectations for western China's economic development.

Interaction Study between Population Mobility and Economic Growth : Evidence from Chongqing

Based on economic convergence model and its derivatives, this paper examines the relationship between popultion mobility and economic growth in Chongqing and its five functional areas by using 2000~2013 panel data. The results show that there exists interactive relationship between population mobility and economic growth, and this interaction is rendered as mutual inhibition. The restrain from economic growth to population mobility shows smaller effect than the reverse. In the sparsely populated areas, economic growth is promoted by population mobility, and in the densely populated areas, economic growth is driven by investment. Therefore, government has to regulate population mobility to achieve sustainable economic growth.

lncRInter:A database of experimentally validated long non-coding RNA interaction

Non-coding regions are the major component of human genomes and the long non-coding RNA（IncRNA）is a class of pervasive genes located in noncoding regions（Morris and Mattick,2014）.IncRNAs play a wide range of regulatory roles in gene transcription,translation,epigenetic modification and protein function by interacting with different types of molecules including DNA,

ABNORMAL SHOOT 6 interacts with KATANIN 1 and SHADE AVOIDANCE 4 to promote cortical microtubule severing and ordering in Arabidopsis

Plant interphase cortical microtubules(cMTs)mediate anisotropic cell expansion in response to environmental and developmental cues.In Arabidopsis thaliana,KATANIN 1(KTN1),the p60 catalytic subunit of the conserved MT-severing enzyme katanin,is essential for cMT ordering and anisotropic cell expansion.However,the regulation of KTN1-mediated cMT severing and ordering remains unclear.In this work,we report that the Arabidopsis IQ67 DOMAIN(IQD)family gene ABNORMAL SHOOT 6(ABS6)encodes a MT-associated protein.Overexpression of ABS6 leads to elongated cotyledons,directional pavement cell expansion,and highly ordered transverse cMT arrays.Genetic suppressor analysis revealed that ABS6-mediated cMT ordering is dependent on KTN1 and SHADE AVOIDANCE 4(SAV4).Live imaging of cMT dynamics showed that both ABS6 and SAV4 function as positive regulators of cMT severing.Furthermore,ABS6 directly interacts with KTN1 and SAV4 and promotes their recruitment to the cMTs.Finally,analysis of loss-of-function mutant combinations showed that ABS6,SAV4,and KTN1 work together to ensure the robust ethylene response in the apical hook of dark-grown seedlings.Together,our findings establish ABS6 and SAV4 as positive regulators of cMT severing and ordering,and highlight the role of cMT dynamics in fine-tuning differential growth in plants.
