Using plant bivalent expression vector pCAMBIA1300 and pBI121 as basic components, a new binary vector harboring tomato chitinase gene Chi3 and tomato β-1,3-glucanase gene Glu-Ac, was constructed through sequential restriction digests and ligations recombination. The two genes driven by CaMV35s promoter were successfully transferred into watermelon cultivars "ZhongYuYiHao" via Agrobacterium-mediated transformation.

构建了同时含有番茄儿丁质酶基因（Chi3）和β-1，3-葡聚糖酶基因的双价抗真菌基因植物表达载体，以西瓜子叶块为外植体，采用根癌农杆菌介导法，将Chi3和Glu-Ac同时导入西瓜栽培种&中育一号&，共获得46株抗性再生植株。

Seeds linear-oblong, not beaked, coma silky white; endosperm copious; cotyledons linear, flat, radicle short.

种子线状长圆形，不发，种缨绢状白色；胚乳丰富线形，平的子叶，胚根短。

The tetrad of megaspores was linear shaped, with one of them being functional.

锥栗胚胎为蓼型，功能大孢子发育成熟时共具有七个细胞八个细胞核，通过双受精作用，产生胚和胚乳，胚胎发育经历球形胚、心形胚、鱼雷形胚到子叶胚的过程。

Herbs aquatic; at least female flowers lacking petals or inconspicuous; fruit splitting at maturity into (2-)4 1-seeded mericarps; leaves whorled, at least the lower ones pinnately divided.

肾形，卵形的叶，或正三角形；四棱形的果圆柱状或，裂爿先端容易与分离在开裂的假隔膜；子叶现任。 2 Myriophyllum 狐尾藻属

Northern-blot analysis demonstrated that the two rice NAP1-like genes are predominantly expressed in stem tissues such as root and shoot apical meristems as well as in young flowers.

我们通过筛选单子叶植物水稻和双子叶植物烟草的cDNA文库，获得了6个NAP1类似蛋白（NAP1 like protein，NAP1_LP）的cDNA，其中水稻的两个NAP1类似蛋白分别命名为OsNAP1_L1和OsNAP1_L2，烟草的4个类似蛋白分别命名为NtNAP1_L1、NtNAP1_L2、NtNAP1_L3和NtNAP1_L4。

The frequency and amplitude of wake force were deduced theoretically, while the influence of stator sector distribution and stator vane quantity on the wake force of vane was also discussed. Transient analysis was conducted for the forcing response of rotor blades under the same stator sector distribution and different quantities of stator vane, so an optimum asymmetry stator mistuned design was developed.

对不对称静子叶片非谐情况下激振力频率幅值进行推导，讨论了静子扇区分布和静叶数目选取对尾流激振力的影响，并对相同扇区分布不同静叶数目情况下转子叶片的强迫响应进行瞬态分析，给出不对称静子非谐设计的最优方案。

In conservative families, there has been little or no change in the number of genes since the divergence between eudicots and monocots ~145 million years ago.

在保守的家族中，基因的数目在大约一亿四千五百万年前(~145MYA)真双子叶植物和单子叶植物发生分化之后都没有改变或者变化甚微。

Although the model doesn't suit to monocots, but it has helped to analyze new genes and gene functions in monocots. Although lilies are among the most important ornamental plants, relatively little research has been conducted on lily flower development.

虽然有证据表明依据拟南芥、金鱼草等双子叶植物提出的ABC模型，并不完全适用于单子叶植物，但是仍然给人们在单子叶植物花发育相关基因的克隆和功能研究中提供了参考和借鉴。

Genus of narrow-leaved European herbs.
