Increasing rice production is important to ensure food security in China. Exploring yield potential and identifying genes beneficial to yield are important goals in the modern rice breeding. Generally, controlling leaf morphology, increasing photosynthesis efficiency and modulating the ＂sink-source＂ relationship can pro- mote the breeding of high-yield rice as well as other cereal crops . The morphology of the leaf includes length, width and degree of curl after its emergence from the meristem and is determined by the establishment of polariW along the adaxial-abaxial, ventral-dorsal and medial-lateral axes and regulated at genetic, hormonal and environmental levels . Rice leaf morphology varies widely among rice subspecies and cultivars. Quantitative trait loci （QTLs） affecting leaf shape commonly have pleiotropic effects on rice yield , which are more useful than mutant genes for studying the molecular mechanism of leaf shape regulation and their application to rice breeding.

The synergy of single atoms （SAs） and nanoparticles （NPs） has demonstrated great potential in promoting the electrocatalytic carbon dioxide reduction reaction （CO2RR）;however,the rationalization of the SAs/NPs proportion remains one challenge for the catalyst ***,a Ni2+-loaded porous poly（ionic liquids）(PIL) precursor synthesized through the free radical self-polymerization of the ionic liquid monomer,1-allyl-3-vinylimidazolium chloride,was pyrolyzed to prepare the Ni,N co-doped carbon materials,in which the proportion of Ni SAs and NPs could be facilely modulated by controlling the annealing *** catalyst Ni-NC-1000 with a moderate proportion of Ni SAs and NPs exhibited high efficiency in the electrocatalytic conversion of CO2into *** Ni K-edge X-ray absorption near-edge structure （XANES） spectra and theoretical calculations were conducted to gain insight into the synergy of Ni SAs and *** charge transfer from Ni NPs to the surrounding carbon layer and then to the Ni SAs resulted in the electron-enriched Ni SAs active *** the electroreduction of CO2,the coexistence of Ni SAs and NPs strengthened the CO2activation and the affinity towards the key intermediate of*COOH,lowering the free energy for the potential-determining*CO2→*COOH step,and therefore promoted the catalysis efficiency.

Composite coatings of bioglass and hydroxyapatite (briefly named HA/BG) with different hydroxyapatite contents on titanium substrate were successfully fabricated. The fabricated coatings are characterized by rough and poriform *** densities of the coatings decrease with the increase of HA content. There is a transition layer with a 5 μm thickness between the BG coating and the substrate. During heat-treatment, hydroxyapatite crystals with hexastyle shape have precipitated from the BG.

一些学者认为清江流域夏商时期的考古学文化属于早期巴文化。通过分析,我们认为清江流域夏商时期的考古学文化可分为两两间存在时间缺环的三类遗存;从目前的考古资料看,还无法支持将清江流域夏商时期的考古学文化推定为早期巴文化这一说法。本文同时还探讨了一些与早期巴文化研究相关的问题。

重庆地区的三星堆文化时期遗存多被学者归入以成都平原为中心的三星堆文化范畴内。但通过比较,我们发现两者间除了存在较多的相似因素外,还有一定的差别,在目前资料还不充足的情况下,似乎不宜简单地将两者归并,作为同一类遗存。重庆地区夏商时期的中坝子遗存在继承了一定的本地文化传统外,除了与成都平原三星堆文化和鄂西地区的朝天嘴文化存在密切交流外,还受到中原地区的文化影响。峡江地区作为东西文化交流的廊道在三星堆文化时期始终是畅通的,这也使得这一地区多见有大量的三星堆文化因素。

夏商西周时期,成都平原的宝墩文化、三星堆文化和十二桥文化与中原地区存在一定程度的文化交流,并在不同阶段呈现出不同特点。文章分三个阶段梳理学界对于两地存在相似形制的陶器、铜器和玉器的研究情况,以此展现出两地间的交流历程。仅从相似形制器物比较的角度开展研究有将问题简单化的倾向,更为深入的探讨应将从中原至成都平原这一广大区域文化间的交流与互动纳入考察范畴,将具体器物的研究与整体文化背景研究紧密结合,这无疑将是一个较为长期的研究过程。

Dysregulation of neurotransmitter metabolism in the central nervous system contributes to mood disorders such as depression, anxiety, and post–traumatic stress disorder. Monoamines and amino acids are important types of neurotransmitters. Our previous results have shown that disco-interacting protein 2 homolog A(Dip2a) knockout mice exhibit brain development disorders and abnormal amino acid metabolism in serum. This suggests that DIP2A is involved in the metabolism of amino acid–associated neurotransmitters. Therefore, we performed targeted neurotransmitter metabolomics analysis and found that Dip2a deficiency caused abnormal metabolism of tryptophan and thyroxine in the basolateral amygdala and medial prefrontal cortex. In addition, acute restraint stress induced a decrease in 5-hydroxytryptamine in the basolateral amygdala. Additionally, Dip2a was abundantly expressed in excitatory neurons of the basolateral amygdala, and deletion of Dip2a in these neurons resulted in hopelessness-like behavior in the tail suspension test. Altogether, these findings demonstrate that DIP2A in the basolateral amygdala may be involved in the regulation of stress susceptibility. This provides critical evidence implicating a role of DIP2A in affective disorders.
