查询词典 apical meristem

The outer layer of apical meristem, from which the epidermis is formed.

表皮原顶端分生组织的外层，表皮就是从这里形成的

Quiescent center A group of cells in the center of the apical meristem in which mitotic divisions are rate or absent.

静止中心：在根的顶端分生组织中心区域的一些细胞，它们几乎不进行有丝分裂。

Leaf is the first lateral organ produced by the activity of the shoot apical meristem.

摘要叶片是茎端分生组织产生的第一类侧生器官，在植物发育中具有重要地位。

The results of in situ hybridization demonstrated that AsPCS was found to be expressed in the apical meristem, epidermis, and vascular cylinder of roots.

另外通过比较该基因在相同处理条件下根中与茎中的表达量，我们发现AsPCS在根中的表达量远高于茎中；5。

And it may work synergistically with AP1 and LFY to modulate the competence to flowering in the shoot apical meristem.

它可以和AP1和LFY蛋白协同作用，促进茎顶端分生组织向花分生组织转化。

The floral primordium is initially circular, along with the edge of which slight concaves occur. The outmost whorl of tepal primordia arises as a result of apical meristem division and the floral primordium then is in the shape of triangle. Two further whorls of tepal primordia arise in spiral acropetal sequence and are alternately arranged. When the innermost whorl of tepal primordia is at the late developmental stage, the foremost stamen primordia arise almost simultaneously in spiral acropetal succession and all of the stamen primordia are ultimately arranged in a triangle-cone form. Late in stamen primordium development, carpel primordia arise as same as the young stamen primordia and grow laterally. Grooves are present on the adaxial side of each carpel and develop into ventral sutures gradually closing up.

观光木的花原基最初为近圆形，随着顶端分生组织的活动，花原基边缘处出现浅凹，形成第一轮花被片原基，此时，花原基呈三角形排列，后两轮花被片原基依次发生，与前一轮互生；在内轮花被片发生的后期，最初几枚雄蕊原基几乎同时出现，呈螺旋状向顶发生，最后排列成三角圆锥状；雄蕊原基发育后期，心皮原基开始发育，形状与发育初期的雄蕊原基相似，随后心皮原基进行侧向生长，在近轴面出现浅凹，进而发育为凹槽，形成腹缝线，最后腹缝线完全愈合。

Calyptogen A layer of meristematic cells covering the root apical meristem in some plants(e.g. grasses) that gives rise to and maintains the root cap.

根冠原：在一些植物中覆盖根顶端分生组织的一层具有分生能力的细胞，根冠原可以产生和维持根冠。

In the plant vegetative growth, leaf primordia arise from groups of initial cells within the peripheral zone of the shoot apical meristem.

叶是植物进行光合作用的器官。为了适应自然环境，植物叶在漫长的进化过程中发展成今天这样的千姿百态。

The trichomes are visible only near the apical meristem; they drop off early, leaving the areoles inconspicuous.

只可见到生长点附近的毛，这些毛很容易就会脱落，使它们远离危险变得不起眼。

Plants modulate their shoot architecture by regulating activities of the shoot apical meristem and axillary meristems.

高等植物通过调节顶端分生组织和侧生分生组织的活性建立地上株型系统，分生组织的活性受环境信号、发育阶段和遗传因素的综合调控，植物激素参与这些信号的整合。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
