1miR164c and miR168a regulate seed vigor in rice^∞显示文摘Micro RNAs(miRNAs)are key regulators of gene expression in many important biological processes of plants.However,few miRNAs have been shown to regulate seed vigor.Here,we conducted microarray assays to analyze miRNA expression levels in seeds of the rice(Oryza sativa L.)cultivar ZR02.Results showed significant differences in the expression of 11 miRNAs between artificially aged and untreated control seeds.Among these,osa-miR164c was transcriptionally upregulated,while osamiR168 a was downregulated in artificially aged seeds;this was verified by quantitative real-time PCR analysis.Under the same aging condition,osa-miR164c overexpression in OE164c transgenic seeds and osa-miR168a silencing in MIM168a transgenic seeds of the rice cultivar Kasalath led to lower germination rates,whereas osa-miR164c silencing Rin MIM164c and osa-miR168a overexpression in OE168a resulted in higher seed germination rates compared with wild-type seeds.Meanwhile,changes in cytomembrane permeability of seeds and in the expression level of osa-miR164c target genes(OsPM27 and OsPSK5)and osamiR168a target genes(OsAGO1 and OsPTR2)under aging conditions coincided with changes in seed vigor induced by osa-miR164c and osa-miR168 a.Thus,genetic manipulation of miRNAs has important implications in the development of crop cultivars with high vigor and extended life span of seeds.Yan Zhou Shiqi Zhou Liping Wang Duo Wu Hailan Cheng Xu Du Dandan Mao Chunlai Zhang Xiaocheng Jiang 2020Journal of Integrative Plant Biology2020,62,4:7
2Recent Development of Photodeformable Crystals:From Materials to Mechanisms显示文摘Photodeformable materials are a class of molecules that can convert photon energy into mechanical energy,which have attracted tremendous attention in the last few decades.Owing to their unique photoinduced deformable properties,including fast lightresponse and diverse mechanical behaviors,photodeformable materials have exhibited great potential in many practical applications such as actuators,photoswitches,artificial muscles,and bioimaging.In this review,we sort out the current state of photodeformable crystals and classify them into six categories by molecular structures:diarylethenes,azobenzenes,anthracenes,olefins,triarylethylenes,and other systems.Three distinct light-responsive mechanisms,photocyclization,trans-cis isomerization,and photodimerization,are revealed to play significant roles in the molecular photodeformation.Their corresponding photodeformable behaviors such as twisting,bending,hopping,bursting,and curling,as well as the potential applications,are also discussed.Furthermore,the challenges and prospective development directions of photodeformable crystals are highlighted.Cheng Huang Rongjuan Huang Simin Zhang Haodong Sun Hailan Wang Beibei Du Yuxin Xiao Tao Yu Wei Huang 2021Research2021,,1:1

4Anatomical variations of segmental bronchi based on big data of somatom definition flash CT显示文摘The aims of this study were to study the branching patterns of segmental bronchi using Somatom Definition Flash CT and explore the gender differences.10000 patients were enrolled.The three dimensional bronchial tree images were acquired using the syngovia post-processing workstation.The directions of travel,openings,and ramifications of the segmental bronchi were observed with the aid of three-dimensional reconstruction and CT virtual bronchoscopy,assisted with lung window images.The branching patterns of the segmental bronchi were then extensively determined and the ratio of the formation patterns of the segmental bronchial branches was statistically analyzed.Javed Saeed Liu Hailan Mei Yixtuan Zhang Yi Liu Cheng Liu Shuwei 2021解剖学杂志2021,44,S01:0
