in Papilionoideae legume, Lotusjaponicus, the development of dorsal-ventral （DV） asymmetric flowers is mainly controlled by two TB1/CYCLOiDEA/PCF （TCP） genes, SQUARED STANDARD （SQU） and KEELED WiNGS iN LOTUS （KEW）, which determine dorsal and lateral identities, respectively. However, the molecular basis of how these two highly homologous genes orchestrate their diverse functions remains unclear. Here, we analyzed their expression levels, and investigated the transcriptional activities of SQUand KEW. We demonstrated that SQU possesses both activation and repression activities, while KEW acts only as an activator. They form homo- and heterodimers, and then collaboraUvely regulate their expression at the transcription level. Furthermore, we identified two types of post-transcriptional modifications, phosphor- ylation and ATP/GTP binding, both of which could affect their transcriptional activities. Mutations in ATP/ GTP binding motifs of SQU and KEW lead to failure of phosphorylation, and transgenic plants bearing the mutant proteins display defective DV asymmetric flower development, indicating that the two conjugate modifications are essential for their diverse functions. Altogether, SQU and KEW activities are precisely modulated at both transcription and post-transcription levels, which might link DV asymmetric flower development to different physiological status and/or signaling pathways.

An online survey addressed to members listed in the European Cooperative Programme for Crop Genetic Resources Networks Working Group on Graithe current problems in the management of GL germplasm, to work out the criterian Legumes and Grain Legumes （GL） germplasm managers and breeders was carded out to pinpoint and decisions involved in the implementation of regeneration procedures and to identify strategic areas where further research is required. The survey was divided into three sections：（1） germplasm collection details and current status of the regeneration needs; （2） assessment over the understanding of basic information required to carry out appropriate regeneration procedures such as the breeding systems, the pollination requirements and pollinating agents, the isolation techniques and regeneration facilities; and （3） assessment of different options, in addition to ＂ex situ＂, such as ＂in situ＂ and ＂on farm＂ conservation. Obtaining, collating and analysing different kinds of existing data on mating system of GL species, effective pollination control methods and isolation facilities by species and location is one example of a priority issue. The GL community makes a clear request for greater support for the development of well-designed methodologies of regeneration that maintain the genetic structure of populations and that the optimum regeneration strategy is most likely to be achieved through integrating pollinators with the regeneration procedures. A major concern of the GL community is the lack of empirical scientific information on the most suitable pollinator agents.

古代人类食谱研究是生物考古的重要组成部分,也是当前国际科技考古领域的研究前沿.利用稳定同位素分析方法,尝试揭示贾湖遗址先民的食物结构以及生活方式的变化.人骨的骨胶原含量、C含量以及N含量,尤其是骨胶原C/N摩尔比的分析表明,28个样品中13个已经受到埋藏环境的污染,不能用作食谱分析.其余样品骨胶原的δ13C((-20.37±0.53)‰),表明先民主要以C3类作为食物来源.根据骨胶原中δ13C和δ15N的不同,先民的食谱可划分为4类.两者相关性的缺乏,当与该遗址以农耕经济为主有关.骨胶原δ15N和羟磷灰石δ13C纵贯整个文化段的变化,反映了先民从狩猎转向采集、捕捞直至发展稻作农业和家畜饲养的改变.而羟磷灰石中δ18O则无明显变化,揭示了该遗址气候较为稳定.

During organ development, many key regulators have been identified in plant genomes, which play a conserved role among plant species to control the organ identities and/or determine the organ size and shape. it is intriguing whether these key regulators can acquire diverse function and be integrated into different molecular pathways among different species, giving rise to the immense diversity of organ forms in nature. in this study, we have characterized and cloned LATHYROiDES （LATH）, a classical locus in pea, whose mutation displays pleiotropic alteration of lateral growth of organs and predominant effects on tendril and dorsal petal development. LATH encodes a WUSCHEL-related home- oboxl （WOX1） transcription factor, which has a conserved function in determining organ lateral growth among different plant species. Furthermore, we showed that LATH regulated the expression level of TENDRiL-LESS （TL）, a key factor in the control of tendril development in compound leaf, and LATH genetically interacted with LOBED STANDARD （LST）, a floral dorsal factor, to affect the dorsal petal identity. Thus, LATH plays multiple roles during organ development in pea： it maintains a conserved function controlling organ lateral outgrowth, and modulates organ identities in compound leaf and zygomorphic flower development, respectively. Our data indicated that a key regulator can play important roles in different aspects of organ development and dedicate to the complexity of the molecular mechanism in the control of organ development so as to create distinct organ forms in different species.
