apical meristem 中文意思是什麼
apical meristem
解釋
頂端分身組織-
Advances on genetic transformation of cotton shoot apical meristem via gene - gun bombardment
以棉花莖尖分生組織為受體進行基因槍轟擊轉化的研究 -
Ground meristem the central region of the apical meristem from which the ground tissues of pith, cortex, medullary rays, and mesophyll differentiate. in root meristem it is also called periblem
基本分生組織：位於頂端分生組織的中部，髓、皮層、髓射線以及葉肉這些基本組織均是由基本分生組織分化而成。根部分生組織也稱為皮層原。 -
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：在一些植物中覆蓋根頂端分生組織的一層具有分生能力的細胞，根冠原可以產生和維持根冠。 -
Labeling tunel method. the cell ultrastructural changes were similar to apoptosis in animal cells : the apical meristemetic cells underwent the programmed cell death. this was first detected in the apex cells of apical meristem, while peripheral cells differentiated gradually into different parts of a floral bud. but all the cells in the floral bud were subjected to the pcd process before it developed into a complete flower. 140bp dna fragment was found to deposit in apical bud during the plant development. the most important role of caspase - 8 was detected by western blot, and the expression of the procaspase - 8 was time - related with the dna frgmentation and the transformation from vegetative to the reproductive growth. these results suggested that pcd was an active process during the differentiation of apical meristem, and the senescence observed in the apical bud was due to the pcd process
顯微超微結構研究表明，短日照條件下豌豆頂芽的衰老過程是從營養生長錐向花芽的轉化，而用dna原位末端標記tunel caspase - 8 western blot和140 bp dna片斷積累的試驗結果證明，轉化為花芽的整個生長錐細胞發生了編程性死亡pcd ，而且其最頂端部分細胞首先發生pcd ，而頂端周圍的分生組織細胞逐漸分化出花芽的各部分，但頂芽最後並沒有發育成為完整的花，所有細胞就都發生pcd ，從而頂芽衰老。 -
Quiescent center a group of cells in the center of the apical meristem in which mitotic divisions are rate or absent
靜止中心：在根的頂端分生組織中心區域的一些細胞，它們幾乎不進行有絲分裂。 -
Leaf is the first lateral organ produced by the activity of the shoot apical meristem ( sam )
摘要葉片（包括子葉）是莖端分生組織產生的第一類側生器官，在植物發育中具有重要地位。 -
The term is used particularly in relation to a part of the apical meristem that later differentiates further
該名詞也用於指隨后進一步發育的頂端分生組織。
