胚

Seeds with bony tegument; endosperm thin; cotyledons oblate, rounded; radicle short.

种子有多骨的皮；胚乳薄；子叶扁球形，绕行；胚根短。

Seed 1; testa absent; endosperm copious; embryo large.

种子1；种皮缺席；胚乳丰富；胚大。

Seed 1; testa absent; endosperm starchy; embryo rather large.

种子1；种皮缺席；胚乳古板；胚相当大。

The contents of thiamin, riboflavin, nicotinic acid, total protein and xylose and the weight were determined separately for each part as well as for the whole grain.

合并吸收层和胚两部中核黄素的含量，约相等或稍高于糊粉层中核黄素的含量；合并吸收层，胚和糊粉层三者约占总含量50—60％。

And why does destroying blastocysts in the name of finding cures evoke such tigerish protests when most fertility clinics have for years routinely disposed of them as medical waste?

还有：妇产专科诊所多少年来一直把胚泡当作医疗垃圾例行公事的处理掉，为何以寻找治疗手段的名义破坏胚泡就引发了如此强烈的抗议。

Tinman dsRNA even caused visceral mesoderm defects and the somatic muscles disruption, yet wingless dsRNA only affected heart precursors and had no effect on visceral mesoderm and somatic muscles, indicationg that the heart-related genes dsRNA interference worked effectively and exclusively in Drosphila

尤其是tinman基因的dsRNA，还引起了肠中胚层缺失和体壁肌肉组织的紊乱，而wingless基因的dsRNA却只影响心脏的形成，而不影响肠中胚层，说明dsRNA干扰具有非常强的特异性，因而不失为研究果蝇心脏发育基因功能的有效方法。

In this exper iment,we took the advantage of RNAi technique,microinjected tinman and singless dsRNA into the early embryos in Drosophila respectively and got these two genes' RNAi phenotypes,which were very similar to that of their mutant,showing heart tube defects or no heart precursors formation.tinman dsRNA eve caused visceral mesoderm defects and the somatic muscles disruption,yet wingless dsRNA only affected heart precursors and had no effect on visceral mesoderm and somatic muscles,indicationg that the heart-related genes dsRNA interference worked effectively and exclusively in Drosophila.

实验运用RNAi技术，分别将tinman和wingless的dsRNA注入果蝇的早期胚胎，得到了这两个基因的dsRNA干扰表型，与两个基因的突变体表型非常相似，都表现为果蝇心脏前体细胞不能形成或心脏管缺失。尤其是tinman基因的dsRNA，还引起了肠中胚层缺失和体壁肌肉组织的紊乱，而wingless基因的dsRNA却只影响心脏的形成，而不影响肠中胚层，说明dsRNA干扰具有非常强的特异性，因而不失为研究果蝇心脏发育基因功能的有效方法。

We reviewed the update on germ-line epimutations of TSGs including the possible mechanisms underlying germ-line epimutations, the possibility of transgenerational inheritance, and their impact on our understanding of human disease.

本文着重对近年来抑癌基因胚系表观突变研究进展作一综述，探讨胚系表观突变可能的产生机制和代间遗传的可能性，并展望其给人类疾病病因研究所带来的深远影响。

In angiosperms where the endosperm is commonly in the triploid condition the development of the endosperm generally precedes the development of the zygote.

Objective To study the incidence of trisomy 18 in NMRI mice and its developmental malformations.

目的 通过对 18三体在 NMRI小鼠发生率的研究及 18三体胚鼠和正常胚鼠的大体形态学对照观察，进一步认识 18三体 NMRI小鼠的生长发育畸形。
