Chromosomal Abnormalities in Rats after Bamboo Flowering in Manipur, India
نویسنده
چکیده
The famine and bamboo flowering are closely related in North-East India. Bamboo flowering causes population explosion of the rat population. The cytological analysis of metaphase from bone marrow cells through karyotype, C-band and Ag-NOR show chromosomal changes like monosomy, trisomy, robertsonian fusion etc. besides 2n=24. How the exploded population gets stabilized is a big question. One hypothesis has been put forward through the chromosomal changes leading to the death or sterility of some or many individuals but the natural or normal population remains more or less constant, as maintained by the unaffected individuals left behind.

Evaluation of genetic relationship between 15 bamboo species of North-East India based on ISSR marker analysis
The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...

متن کاملFlowering of Woody Bamboo in Tissue Culture Systems
Flowering and subsequent seed set are not only normal activities in the life of most plants, but constitute the very reason for their existence. Woody bamboos can take a long time to flower, even over 100 years. This makes it difficult to breed bamboo, since flowering time cannot be predicted and passing through each generation takes too long. Another unique characteristic of woody bamboo is th...

Chusquea ramosissima is a native monocarpic bamboo species growing in subtropical forests of northeastern Argentina, which can dominate gaps and open forests in the region, particularly after human disturbance. This bamboo species started to flower in different areas of northeastern Argentina in 2001, with the flowering peak during 2002 and 2003 and small isolated flowering events still occurri...

Question: What changes occur as a consequence of the massive flowering and senescence of the dominant understory species of bamboo, Chusquea culeou (E. Desvaux)? In this study, we documented some of the ecological consequences of this rare event that occurred in 2001, the previous flowering having occurred more than 60 years ago. Location: Nothofagus temperate forest, Patagonia, Argentina. Meth...
