Plant architecture determines grain production in rice(Oryza sativa) and is affected by important agronomic traits such as tillering,plant height,and panicle *** key genes involved in controlling the initiation and outgrowth of axillary buds,the elongation of stems,and the architecture of inflorescences have been isolated and *** studies have shown that SiPf40,which was identified from a foxtail millet(Setaria italica) immature seed cDNA library,causes extra branches and tillers in SiPf40-transgenic tobacco and foxtail millet,*** reconfirm its function,we generated transgenic rice plants overexpressing SiPf40 under the control of the ubiquitin ***40-overexpressing transgenic plants have a greater tillering number and a wider tiller angle than wild-type *** root architecture is modified by the promotion of lateral root development,and the distribution of xylem and phloem in the vascular bundle is *** of hormone levels showed that the ratios of indole-3-acetic acid/zeatin(IAA/ZR) and IAA/gibberellic acid(IAA/GA) decreased in SiPf40-transgenic plants compared with wild-type *** findings strongly suggest that SiPf40 plays an important role in plant architecture.

The phylogenetic relationship of Hexapoda has been debated for a long time, which will be resolved mainly depending on the settlement of monophyly, affinities and interrelationships among Protura, Collembola and Diplura. Mitochondrial 12sRNA gene about 355 bp fragments from one proturan species, two collembolan species, two dipluran species and one oribatid species were sequenced. The Ki-mura 2-parameter distances were calculated and a series of molecular phylogenetic trees were reconstructed by using the N-J method, from which the following points were drawn: (i) Protura and Collembola compose a monophyletic group representing absent-cerci; (ii) Diplura is not a monophyletic group, in which Campodeoid with filiform cerci belongs to a clade and Japygoid with pincer cerci and Ectognatha compose another clade, that is, Insecta s. str. stemmed from Japygoid. So it would be suggested that the phylogenetic relationship of Hexapoda is [Parainsecta (Collembola + Protura) +Campodeoid +Insecta (Japygoid +

为了研究稻米中镉(Cd)的生物可给性与稻米理化性质之间的相互关系以及稻米摄入而导致的Cd健康风险,从湖南某些地区采集了16个稻米样品,利用in vitro方法研究了这些稻米中Cd的生物可给性及其人体健康风险。结果表明:在16个样品中,有13个样品的Cd含量超过稻米中Cd的限量标准(0.2 mg·kg-1)。稻米中Cd的溶解态含量及其生物可给性变化较大,胃阶段和肠阶段Cd的溶解态含量范围分别为0.102~1.70 mg·kg-1和0.015~0.249 mg·kg-1,平均值分别为0.698 mg·kg-1和0.103 mg·kg-1,胃阶段和肠阶段Cd的生物可给性的范围分别为56.8%~82.0%和6.62%~15.9%,平均值分别为70.9%和11.1%。模拟肠液中Cd的溶解态含量与稻米的纤维含量之间有显著的相关性。如果不考虑稻米中Cd的生物可给性,所采集的所有稻米样品的摄入都将导致成人和儿童健康风险。如果我们考虑了稻米中的生物可给性,只有31%的稻米样品会对成人产生健康风险,将有50%的稻米样品会对儿童产生健康风险。

通过在土壤中施加外源无机碘KI和KIO3,研究了西瓜对外源无机碘的吸收和利用。同时,通过对成熟期西瓜主要生长生理指标的调查,研究了土壤中外源碘的施加对西瓜生长的影响。结果表明,西瓜植株可以吸收土壤中的碘,并可以在植株根部、茎部、叶部、果皮和果瓤中积累。西瓜植株不同部位对外源碘的吸收和富集能力存在明显差异,根部>叶部>茎部>果皮>果瓤,这种分布能力在KI处理和KIO3处理上具有相似表现。其中,不同浓度外源碘处理条件下,果瓤中碘含量分别为对照中的3.23～28.94倍。土壤中外源施加无机碘没有影响西瓜植株的正常生长,没有影响西瓜产量和果实品质。

Taxonomy plays an important role in understanding the origin, evolution, and ecological functionality of biodiversity. There are large number of unknown species yet to be described by taxonomists, which together with their ecosystem services cannot be effectively protected prior to description. Despite this, taxonomy has been increasingly underrated insufficient funds and permanent positions to retain young talents. Further, the impact factordriven evaluation systems in China exacerbate this downward trend, so alternative evaluation metrics are urgently necessary. When the current generation of outstanding taxonomists retires,there will be too few remaining taxonomists left to train the next generation. In light of these challenges, all co-authors worked together on this paper to analyze the current situation of taxonomy and put out a joint call for immediate actions to advance taxonomy in China.

Maize seedling blight caused by Fusarium verticillioides is a widely occurring maize disease,but the genetics and mechanisms of resistance are not well *** this study,GWAS performed by MLM and 3VmrMLM identified 40 and 20 QTNs,associated with seedling blight *** methods identified 49 and 36 genes,*** verification of candidate gene ZmSBR1 identified by both methods showed that the resistance of a mutant line to seedling blight decreased by 0.37 grade points after inoculation with ***,compared with the *** length of the stem rot lesion caused by *** increased by 86%in mutant seedlings,and the relative length of the adult plant stalk rot increased by 35%in mutant plants compared to the wild type after inoculation with Fusarium *** analysis showed that expression of defense-related genes after inoculation was down-regulated in the mutant compared to the wild type,synthesis of secondary metabolites associated with resistance was reduced,and the immune response triggered by PAMP decreased,resulting in decreased resistance of mutant maize *** gene association analysis showed that most maize inbred lines carried the susceptible haplotype.A functional PCR marker was *** results demonstrated that ZmSBR1 conferred resistance to multiple Fusarium diseases at the seedling and adult growth stages and had important application value in breeding.
