查询词典 bundle-sheath

In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3-phosphate, the first step in the Calvin cycle.

在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸，后被运到邻近的维管束鞘细胞，在那里二氧化碳被释放，后被核酮糖二磷酸羧化酶固定形成3－磷酸甘油酸，这是卡尔文的循环第一步。

Grass leaf with Kranz anatomy --- C4 plant 有花环结构的禾草 Two bundle sheathsOuter one is parenchymatous; inner is a mestome sheath ??

用C4植物来表示。其维管束鞘只有1层细胞，有花环形结构，是高效光合作用植物，如玉米、高梁、甘蔗以及桑科的一些种类。C4植物能把叶肉细胞中所放出的CO2能被再次利用。

This observation provided a strong support to the point that most leaves export the most of assimilates in the light time. Plasmodesmal densities between SE/CC, CC/PP, PP/PP and PP/BSC (bundle-sheath cell) decreased in weak light. Plasmodesmata were observed between CC/SE (nacreous-walled sieve element), PP/BSC in branch veins in normal light intensity, but not in weak light. Thus apoplasmic pathway may be the main mode of transport of assimilates in weak light, however symplasmic pathway may be the main mode of transport of assimilates in normal light intensity.

在筛管/伴胞、伴胞/韧皮薄壁细胞、韧皮薄壁细胞/韧皮薄壁细胞和韧皮薄壁细胞/维管束鞘细胞之间的胞间连丝密度都在弱光条件下下降，在正常光照强度下支脉筛管/伴胞和韧皮薄壁细胞/维管束鞘细胞之间可以观察到胞间连丝，而在弱光下几乎观察不到胞间连丝的存在，所以同化物的运输在弱光条件下可能以质外体运输为主，而在正常光照强度下，共质体运输可能是主要的运输方式。

CaMK was mainly accumulated in vascular bundle sheath cells of leaves and highly expressed in lateral root primordia and root tips. But the kinase was under detectable in other regions.

在营养器官中钙调素激酶主要分布于叶的维管束鞘细胞、侧根原基和根尖等部位，而其它部位没有检测到明显的分布。

Needles 2(or 3) per bundle, dark green, semiorbicular in cross section, 6-15 cm × 1-1.5 mm, resin canals 5-9, marginal, rarely 1 or 2 median, base with persistent sheath initially 1-2 cm. Pollen cones 5-9 mm. Seed cones shortly pedunculate, initially green, turning yellowish brown to brown at maturity, ovoid to ovoid-globose, 2.5-9 × 4-9 cm, usually persistent for a few years.

每包的针叶2(或3)，深绿色，半圆形的在横断面上， 6-15厘米×1-1.5毫米，树脂道5-9，边缘，很少1或2 中位数，基部具宿存鞘最初1-2 厘米雄球花5-9毫米球果有短花序梗，最初绿色，转身成熟时到棕色黄棕色， 2.5-9 * 4-9 厘米，几年的通常宿存。

The cells of the bundle sheath that surround the vascular tissues are large and contain specialized elongated chloroplasts that do not contain grana, but form starch grains.

它的特点为：围绕在维管组织外层的维管束薄壁细胞较大，并含有较大的叶绿体，这些叶绿体中不含基粒，但形成淀粉粒。

Electro microscope analysis showed that NO promoted the chloroplast development, as indicated by increased number and size of chloroplast in both the mesophyll cell and bundle sheath cell of the leaves, and well-developed stroma lamellae and grana as well as increased numbers.

电镜观察结果证实，NO促进了玉米叶片叶肉细胞和维管束鞘细胞中叶绿体的发育，叶绿体数量增多且体积增大，基质片层和基粒数量明显增多且结构完好。

There was no apparent structure of vasicular bundle sheath in the leaves. Thick cuticle layer was found on both abaxial and adaxial surfaces.

荔枝叶片叶肉组织内细胞的排列，除了在5天叶龄的幼叶排列非常紧密之外，其余叶龄的叶肉组织都会发现有空隙的存在。

Semi-thin sectioning and the method c.ommonly referred in histochemistry were used to study the development of vascular bundles in Aloe arborescens leaves with emphasis on the origins and tissue types of vascular bundle sheath cells and aloin-containing cells.

采用半薄切片和组织化学方法研究了木立芦荟叶内维管束的发育过程，并着重于维管束鞘细胞和芦荟素细胞的来源及组织类型。

Chloroplasts with numerous starch grains and few mitochondrias were noticed in the mesophyll cell surrounding the bundle sheath in weak light. The storage of starch grains appeared to result from an unbalance between photosynthate production and export of photosynthates.

淀粉粒的积累可能是由于光合同化产物的生产与输出之间的不平衡，这一观察结果有力地支持了大部分叶片是在光照条件下输出其大部分同化产物的观点。

Putt your way through 36 fun-filled holes of minigolf on 3D designed courses with elevated greens, bunkers, bridges and water hazards, among other crazy obstacles.

您的推杆方式，通过36个有趣的填孔迷你的三维设计的课程，以提升绿党，掩体，桥梁和水的危害，除其他疯狂的障碍。

Some participles can be used either as attributes or as predicatives.
