Of alfalfa grass against as many as 65 kinds of products, including dicotyledonous weeds against the most serious, there are: Ma theophrasti, Xanthium, green salsa, salsa fin, Cephalanoplos vegetables, Salsola collina, flat hair, trionum wild, East City, quinoa, small Chenopodium, Portulaca oleracea, Amaranthus retroflexus, Capsella bursa-pastoris, iron amaranth, playing a bowl of flowers, vegetables brachyotus Chicory; monocotyledons mainly Setaria grass, barnyard grass, Chloris virgata, reed, Dichotomanthes grass, Digitaria Descurainia sophia, and so on.

对苜蓿有危害的杂草多达65个种，其中以双子叶杂草危害最为严重，主要有：苘麻、苍耳、灰绿碱蓬、翅碱蓬、刺儿菜、猪毛菜、扁蓄、野西瓜苗、东亚市藜、小藜、马齿苋、反枝苋、荠菜、铁苋菜、打碗花、苣荬菜；单子叶杂草主要有狗尾草、稗草、虎尾草、芦苇、牛筋草、播娘蒿和马唐等。

At present, regeneration system of cotyledons, hypocotyls, and stems, protoplasts and cotyledons codes have been established among Cucurbitaceae. There are several methods of transformation, such as agrobacteria -medidated genetic, particle gun, pollen tube passage, DNA soaking, ovary embryonary sac injection. Transgenic is tending to antivirotic and delayed maturity. Selection marker used often is NPT II.

目前，在葫芦科植物中已建立了子叶、茎尖、胚轴、茎段、原生质体和子叶节等的再生体系；用于遗传转化的方法有农杆菌介导法、基因枪法、花粉管通道法、DNA浸泡法等；用于转化的目的基因多为抗病毒病基因和延迟成熟的基因；NPTII基因为最常用的筛选标记基因。

In this review, we use Arabidopsis thaliana and Oryza sativa as examples, and summarize the study results of floral homeotic MADS-box genes in two major groups of angiosperms — core eudicots and monocots — over the past decade. Our aim was to review the functional conservation and diversity of floral homeotic MADS-box genes in angiosperms and discuss whether the ABCDE model has been conserved in monocotyledons.

本文以模式植物拟南芥和水稻为例，综述了近10年来对被子植物两大主要类群——核心真双子叶植物和单子叶植物花同源异型MADS-box基因的研究成果，分析MADS-box基因在被子植物中的功能保守性和多样性，同时探讨双子叶植物花发育的ABCDE模型在多大程度上适用于单子叶植物。

It is composed mainly of monotypic and oligotypic genera and is distributed mainly in eastern Asia.

木通科为双子叶植物纲中较原始的一个小科，多为寡种属和单种属，主要分布于东亚地区。

Since the first identification and cloning of a SUT cDNA from spinach, many SUT cDNAs have been cloned and characterized in 34 different plant species, in both dicots and monocots.

自从菠菜中克隆到第一个SUT基因以来，已先后有多个SUT基因的cDNA得到克隆与功能分析，涉及34种双子叶与单子叶植物。
