查询词典 pericycle

The vascular bundles of the stem are arranged in a ring within a single endodermis and pericycle, giving a eustele.

茎内的维管束在皮层和中柱鞘内排列成环状，形成真中柱。

The stele includes all primary tissues derived from the procambium consists of pericycle,phloem and xylem.

中柱包括从原形成层衍生而来的全部初生组织，由中柱鞘、韧质部和木质部组成。

Pericycle The parenchymatous layer of cells that lies within the endodermis,forming the outermost part of the stele.

中柱鞘：位于内皮层以内紧挨内皮层的一层或几层薄壁细胞，形成中柱的最外部分。

Rice lateral root primordia initiated only from the pericycle cells adjacent to the phloem poles, indicating that initiation of rice lateral root primordia had specific cell type pattern.

3水稻侧根原基起始具有严格的细胞位置效应，只有与韧皮部极直接相邻的中柱鞘细胞才能分化形成侧根原基。

Eustele The STELE arrangement found in most gymnosperms and dicotyledons in which the vascular tissue is arranged into a ring of discrete bundles separated by medullary rays, all contained within a single ring of endodermis and pericycle.

真中柱：发现于大多数裸子植物和双子叶植物的中柱类型，其维管组织由不连续的，被髓射线分开维管束排列成环状。所有的微观组织都包含在内皮层和中柱鞘以内。

Although both of FDRMADS7 and FDRMADS8 wereexpressed in the root, they have different expression pattern.The transcripts of FDRMADS7 weredetected throughout the root,especially the expression in the root meristem was the highest.However,the expression of FDRMADS8 was mainly localized in elongation and mature rigion.No apparent expression signal was detected in the root cap, root meristem and pericycle cells.

虽然FDRMADS7和FDRMADS8都在根中表达，但它们在根中的表达模式也不相同：FDRMADS7在根中到处表达，尤以生长点处表达量最高；而FDRMADS8在伸长区和根毛区的皮层中有大量表达，在根冠，根尖分生区和根毛区的中柱鞘细胞中却无明显表达，暗示它们在根中行使的功能也不相同。

Pekinensis . IAA at concentration of 0.4-1. 0 mg/L in solid MS medium incited many adventitious roots on hypocotyl segments. The earliest anatomic changes were observed on cut surface of hypocotyl segments under optical microscope 24 hours after IAA treatment: cytoplasmic and nuclear density became higher in a few of parenchytmatous cells adjacent to phloem in tissue of pericycle, followed by cell divisions.

在生长素诱导24h后，可借助显微切片观察到下胚轴切面附近明显的解剖学变化：首先是中柱鞘内靠近韧皮部的薄壁细胞的细胞质与细胞核变浓，染色加深，部分细胞分裂；随后是分裂的细胞团增大，逐渐形成根原基并分化出根冠。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
