With tile ovary maturing, the orifice was narrowed because of tile ovary growth at last fused completely. The gynoecium is composed of a single carpel.(1) In tile series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when tile mouth of ovary was formed.

Tyrosinase OT47 was expressed specifically in the outer epithelial cells of the middle mantle fold, suggesting that it contributes to periostracum formation and the periostracum secretion model of P. fucata is different from previous opinion.

其中，合浦珠母贝酪氨酸酶OT47的基因特异性的表达于外套膜中褶外侧上皮细胞，可能与角质层形成有关，同时表明合浦珠母贝角质层形成可能具有其独特的细胞分泌模式。

In the midst of this growing and important stress, the broker became suddenly aware of a high-rolled 28fringe of golden hair under a nodding 29canopy of velvet and 30ostrich tips, an imitation sealskin 31sacque and a string of beads as large as 32hickory nuts, ending near the floor with a silver heart.

就在这个愈发紧张和重要的时刻，经纪人突然注意到一顶带鸵鸟毛羽饰、微微抖动的丝绒帽下那高高卷起的金发刘海，一件宽大的人造海豹皮上衣，一串用大如山核桃的珠子穿成，吊着个心形银坠，几乎垂到地板上的珠链。

Inflorescences conical; bracts connate laterally for ca. 1/2 their length, forming basal pouches, each subtending a cincinnus of 2--7 flowers

茎切开有红汁；侧小叶在一侧强烈不对称，比顶生的小叶大；在雌花里有许多的心皮；每心皮1胚珠；成熟的心皮20 --40螺旋榨排列在一扩大的花托上 11 Curcuma 姜黄属

Temporally, rhizobium abundance in root and pericarp is obviously higher at pod-bearing stage than any other growth stage. Rhizobium abundance in various floral organs rapidly increases after pollination. During ovary-to-legume germinative process, rhizobium abundance in ovary wall and ovule increases logarithmically. Endogenous rhizobia are found in ovule only after fertilization, and rhizobium abundance in young seeds is higher than in fertilized ovule. This implies that endogenous rhizobia can be transported and colonized in early germinated seedlings.

在时间上，结荚期根、荚果皮内的根瘤菌数量明显高于其他时期；花内各器官在授粉后根瘤菌数量迅速增加；由子房向荚果发育的过程中，子房壁和胚珠内的根瘤菌数量随时间呈对数增长；胚珠在受精后即存在有内生根瘤菌，并且幼嫩种子内生根瘤菌数量远高于受精胚珠，证明内生根瘤菌能被转运并定殖在发育早期的种子中。

METHODS:Nestin expression was detected in 33 cases of neuroepithelial tumors using the immunocytochemical staining. The Nestin positive and negative cells were isolated by magnetic activated cell sorting. Nestin positive cells were culutered, identified, and induced to differentiate. The expression of Nestin protein was detected in Nestin+ cells by RTPCR.
