Styles of Physalis pruinosa L. and P. ixocarpa Brot. were fixed in a modification of Carnoy's fixative (alcohol, chloroform, acetic acid; 3:2:1) 48 hr after pollination. After 24 hr, the styles were transferred to a 5% aqueous pectinase solution (adjusted to pH 4) on a spot plate for 24 hr.

An ultrastructural study of cytomixis in tobacco pollen mother cells

Protoplasma, 2011
Intercellular chromatin migration (cytomixis) in the pollen mother cells of two tobacco (Nicotiana tabacum L.) lines was analyzed by electron microscopy during the first meiotic prophase. The maximal manifestation of cytomixis was observed in the pachytene.

Chromatin attachment to nuclear membrane of wheat pollen mother cells

Nature, 1974
THE cellular mechanisms through which homologues recognise each other before meiosis are unresolved. The problem is compounded in a polyploid species like Triticum aestivum which contains three diploid sets of genetically similar chromosomes1. At meiosis, pairing normally takes place only between the fully homologous partners of a set, so that in spite

Cell-specific Analysis of the Tomato Pollen Proteome from Pollen Mother Cell to Mature Pollen Provides Evidence for Developmental Priming

Journal of Proteome Research, 2013
Tomato is a globally important crop grown and consumed worldwide. Its reproductive activity is highly sensitive to environmental fluctuations, for instance temperature and drought. Here, pollen development is one of the most decisive processes. The present study aims for the identification of cell-specific proteins during pollen developmental stages of

Isolation and culture studies on pollen tetrad and pollen mother-cell protoplasts

Plant Science Letters, 1974
Abstract Techniques have been refined for the isolation and culture of pollen tetrad and pollen mother-cell (PMC) protoplasts from several angiosperms. The tetrads and PMC are treated with 0.75% Helicase in 10% sucrose solution at 22–25°, and within 1 h, nearly 100% of the protoplasts are released from their massive callose walls.
