Title

IRREGULAR MEIOTIC BEHAVIOUR RESULTED INTO ABNORMAL SPORAD FORMATION AND LOW POLLEN FERTILITY IN TWO ACCESSIONS OF CALTHA PALUSTRIS

Authors

Abstract

In the present study, we report the phenomenon of cytomixis in some individuals of Caltha palustris showing chromatin transfer at the different stages of meiosis I. In most of the cases, two to six PMCs are involved in chromatin transfer. The migration of chromatin is either complete or partial, resulting in denucleated, hypoploid and hyperploid PMCs. Single or multiple cytoplasmic channels between two or more proximate PMCs have been observed at prophase I. PMCs involved in cytomixis showed various other meiotic irregularities such as spindle abnormalities, chromatin stickiness, asynchronous disjunction of bivalents and laggards. In the present case, the cytomixis and associated meiotic irregularities cause a significant reduction in pollen fertility, and resulted into the formation of heterogeneous-sized pollen grains. The role of such variably sized fertile pollen grains in the origin of polyploids and aneuploids can not be ruled out.

Key Words

Caltha palustris, cytomixis, meiotic irregularities, chromatin stickiness, pollen grains
