The meaning of ROOT CANAL is the part of the pulp cavity lying in the root of a tooth; also : a dental operation to save a tooth by removing the contents of its root canal and filling the cavity with a protective substance. How to use root canal in a sen
首先通过cap_init()初始化存放cap能力值的状态,随后通过cap_set_flag函数的调用,将三种位图的能力设置给了变量caps,再通过cap_set_proc(caps)设定当前进程的能力值,通过cap_get_proc()返回当前进程的能力值,最后通过cap_free(caps)释放能力值。 cap_set_flag函数的原型是 int cap_set_flag(cap_t cap_p, cap...
The ultrastructure of root cap columella cells was studied by morphometric analysis in wild-type, a reduced-starch mutant, and a starchless mutant of Arabi... MM Guisinger,JZ Kiss - 《American Journal of Botany》 被引量: 249发表: 1999年 Plastid Sedimentation Kinetics in Roots of Wild-Type ...
The plant root cap mediates the direction of root tip growth and protects internal cells. Root cap cells are continuously produced from distal stem cells, and the phytohormone auxin provides position information for root distal organization. Here, we identify the Arabidopsis thaliana auxin response fac...
The root cap also regulates the responses of roots to gravity. Cells of the root cap form by continuous divisions of root cap initials located along the junction between the root cap and the apical meristem (Chapter 3). As a root elongates, peripheral cells of the root cap are shed. ...
root cap - thimble-shaped mass of cells covering and protecting the growing tip of a root rootlet - small root or division of a root root hair - thin hairlike outgrowth of an epidermal cell just behind the tip; absorbs nutrients from the soil prop root - a root that grows from and sup...
The root cap has a central role in root growth, determining the growth trajectory and facilitating penetration into the soil. Root cap cells have specialized functions and morphologies, and border cells are released into the rhizosphere by specific cell wall modifications. Here, we demonstrate that ...
Light-induced inhibition of the elongation of primary roots of Zea mays seedlings is dependent upon the perception of light by the root cap. Separate exposure of detached root caps and roots from which root caps have been removed (i.e. decapped roots) to white light or darkness has shown ...
As a consequence, the apex-specific place of gravity perception in the root cap has evolved to be separated from the place of the growth response necessitating a new signaling mechanism between these tissues (Fig. 5). This has been enabled by the evolution of a new type of PIN auxin ...
