摘要

这项对南印度泰米尔纳德邦蒂鲁内维利地区的 Isoetes coromandelina L.f（Isoetaceae）的细胞学研究表明，在减数分裂过程中，巨孢子母细胞中存在 22 条单独的染色体和一个片段（n=2n=22+1），而不存在任何二价体。两个巨型孢子之间的细胞混合非常常见，导致形成高比例的流产孢子。正如亚伯拉罕（Abraham）和尼南（Ninan）在喀拉拉邦和卡纳塔克邦所报告的那样，本材料属于无配子类群，具有减数分裂不同步现象。

Apogamous Isoetes coromandelina L.f. (Isoetaceae) with asynaptic meiosis

This cytological study on Isoetes coromandelina L.f (Isoetaceae) from Tirunelveli District, Tamil Nadu, South India shows the presence of twenty two individual chromosomes along with a fragment (n=2n=22+1) during meiosis in megaspore mother cells without the presence of any bivalent. Cytomixis between two megaspores is very common, resulting in the formation of a high percentage of abortive spores. The present material is of an apogamous taxon with asynaptic Meiosis as reported by Abraham and Ninan from Kerala and Karnataka.

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
