    • 摘要: 为构建南岭山区杉木Cunninghamia lanceolata大径材高效培育技术体系,提高南岭山区杉木大径材产量与质量,对杉木新造林大径材高效培育试验在3年生时林分生长情况作分析。结果表明:杉木树高、胸径和单株材积在不同品系间存在较显著或极显著差异,在南岭山区培育杉木大径材应选择无性系T-c07、2.5代种子园种;不同种植密度间林分生长总体上不存在显著差异,随着株行距增大树高和单位面积蓄积总体上逐渐减少,胸径和单株材积逐渐增大,南岭山区杉木大径材培育宜采用株行距2 m×2 m、2 m×3 m、4 m×3 m;施肥对林分生长有明显促进作用,不同施肥处理间树高、胸径、单株材积存在不同程度差异,氮磷双因素效应和氮、磷单因素两类拟合与最优用量分析结果表明,大径材培育新造林试验地对氮肥需要处于中等偏下水平,而对于磷肥的需求处于中等偏上的水平。采用优良品种配以合理施肥等培育措施对幼林生长具有显著的促进效果。

    • 摘要: Genetic engineering techniques are bringing new promise approaches in controlling mosquitoand mosquito borne pathogens. Two genetic control strategies are currently involved as either to suppress target populations or to introduce a harm-reducing novel trait. Self-limiting strategies had been proved with limited persistence, whereas self-sustaining strategies intended to persist indefinitely in the target population and bring high risk to invade un-targeting populations. The field trials have been shown completed and ongoing efforts on the genetic engineer mosquitoes were still carried out due to refractory and /or suppressing factors.%蚊媒病是严重的公共卫生问题,遗传控制策略用于蚊虫的控制,它具有种特异性、环境友好、创新性等特点,本文对遗传控制策略的目标、分类及实际应用进展等进行了概述.

    • 摘要: Many tephritid fruit flies are economically important pest species that can destroy fruits and vegetables, bringing can be a barrier to international trades. The Sterile Insect Technique ( SIT) , a species-specific and environment-friendly pest control method, has been proven to be highly effective against tephritid pests. Genetic engineering has a potential to bring great improvements to SIT and facilitate its applicability to more insect pests. Much progress has been made in the area, which also became a frontier of genetic innovation. Here we describe the principles of lethality systems based on the tet-off inducible gene expression system, same case studies from Drosophila and tephritid fruit flies for the improvement of SIT, and the application of similar systems to other agricultur-al insects. The progress to develop a genetic control system on Bactrocera dorsalis is also briefly reported here. The genetic control strategies based on genetic engineering and SIT is believed to play a great role in the Integrated Pest Management ( IPM) of tephritid fruit flies and other agricultural insect pests in the future.%实蝇类害虫严重危害多种水果和蔬菜,是世界果蔬产业最重要的害虫类群之一,严重影响了发生地的果蔬生产和出口贸易活动。昆虫不育技术( SIT)是一种物种特异和环境友好型防治措施,在多种实蝇类害虫的防治、阻截和根除中起到了不可替代的重要作用。通过分子生物学技术对昆虫的基因组进行遗传修饰,可对SIT进行改进,提高其防控效果并扩大应用的物种范围,近年来相关方面的研究已取得重要进展,成为害虫遗传控制的研究热点。本文阐述了通过受四环素调控的tet-off基因表达系统来实现昆虫“不育”的基本原理和在果蝇及其他几种主要实蝇类害虫中建立的不同类型的遗传控制体系,以及类似体系在其他农业昆虫中的应用情况。简要介绍了在橘小实蝇遗传控制技术体系构建方面的工作进展,并对该技术的在害虫综合治理( IPM)尤其是实蝇类害虫防治中的应用前景进行了讨论和展望。

    • 摘要: 无融合生殖是一种不发生雌雄配子核融合而产生种子的一种无性繁殖过程。有些无融合生殖产生的种子是其母本的克隆,可以保留母本的基因型,因此无融合生殖可用于杂种优势的固定。尽管无融合生殖具有潜在的应用价值,但其形成机理十分复杂,表现在无融合生殖有多种表现形式,且受控的途径多样,遗传机制复杂,至今尚无定论,研究方法也多种多样。对近年来无融合生殖研究方面取得的进展进行了概述,旨在为深入研究无融合生殖提供参考。%Apomixis is an asexual propagation through seeds in which embryo is formed without the nuclear fusion of male and female gametes. Since some resultant seeds of apomixis are clones of their maternal parent, they are identical to their maternal parent in genotype. Therefore, apomixis could be used in the fixation of heterosis. Apomixes has abundant potential application values, however, the mechanism for apomictic formation is very complicated, which was represented by multi-forms of apomixis that are controlled by varied pathways, the complicated genetic mechanism that has not been determined and finalized, and diverse methods of studying it. In recent years, apomixis has been studied in terms of linkage analysis. This paper outlines research progress on apomixis, aiming at providing references for in-depth study.

    • 摘要: Floral symmetry is a classical feature of floral diversity. Actinomorphy and zygomorphy are two main types of floral symmetry in angiosperms. Zygomorphic flowers are thought to have evolved from ancestors whose flowers are actinomorphic. Transition from actinomorphy to zygomorphy has been recognized as a key innovation and is considered crucial in the rapid diversification of angiosperms. In recent years, great progress has been made towards understanding the mechanisms underlying changes in floral symmetry during the evolution of angiosperms in wide-ranging botanical disciplines. Evidence from floral development studies indicates that zygomorphy appears before organ initiation, and persists throughout floral development, or appears later at various stages of development. Reduction, suppression and differential elaboration of floral organs are the major determinants of zygomophy. Floral symmetry is strongly selected by pollinators during the different stages of pollination process. In addition, the tighter flower-pollinator interaction found in zygomorhpic flowers may contribute to increased reproductive success through increased precision in pollen placement on the pollinator's body. The molecular base of flower symmetry has been explored in core eudicots, and available evidence indicates that CYC-like genes play an important role in the control of zygomorphy. Future prospects in the study of floral symmetry in development biology, pollination biology and molecular genetics are discussed.%花对称性(floral symmetry)是被子植物花部结构的典型特性之一,主要有辐射对称和两侧对称两种形式.被子植物初始起源的花为辐射对称,而两侧对称的花则是由辐射对称的花演变而来.两侧对称的花部结构是被子植物进化过程中的一个关键的革新,被认为是物种形成和分化的关键推动力之一.近年来有关花对称性的形成和进化机制的研究在植物学科的不同领域均取得了长足的进展.本文综述了花对称性在发育生物学、传粉生物学、生殖生态学及分子生物学等方面的研究进展.两侧对称形成于被子植物花器官发育的起始阶段,随后贯穿整个花器官发育过程或者出现在花器官发育后期的不同阶段.花器官发育过程中一种或多种类型器官的败育以及特异性花器官结构的形成是两侧对称形成的主要原因.研究表明,在传粉过程的不同阶段,花对称性均会受到传粉昆虫介导的选择作用.相比辐射对称的花,两侧对称的花提高了特异性传粉者的选择作用,增加了花粉落置的精确性,进而确保了其生殖成功.花对称性的分子机理已经在多种双子叶植物中进行了深入的研究.现有的证据表明,CYC同源基因在花对称性的分子调控方面起着非常重要的作用.花对称性在被子植物进化过程中是如何起源,与其他花部构成之间是否协同作用,一些不符合一般模式的科属其花对称性的形成机制等都是今后要进一步研究的命题.
