Cytology and Microscopy: Immunolocalization of Covalently Modified Histone Marks on Barley Mitotic Chromosomes
Authors:  Isabelle Colas, Katie Baker and Andrew J. Flavell, date: 06/20/2016, view: 7694, Q&A: 0
Barley is a diploid inbreeding crop with a genome of 5 GB organized into seven chromosomes. The relatively low chromosome number and their large size make barley an excellent model for chromosome cytogenetic studies of large genome cereal crops. ...

Analysis of Chromosome Condensation/Decondensation During Mitosis by EdU Incorporation in Nigella damascena L. Seedling Roots
Author:  Eugene V. Sheval, date: 02/05/2018, view: 4814, Q&A: 0
To investigate the chromosome dynamics during mitosis, it is convenient to mark the discrete chromosome foci and then analyze their spatial rearrangements during prophase condensation and telophase decondensation. To label the chromosome regions in ...

Automated Tracking of Root for Confocal Time-lapse Imaging of Cellular Processes
Authors:  Mehdi Doumane, Claire Lionnet, Vincent Bayle, Yvon Jaillais and Marie-Cécile Caillaud, date: 04/20/2017, view: 9021, Q&A: 0
Here we describe a protocol that enables to automatically perform time-lapse imaging of growing root tips for several hours. Plants roots expressing fluorescent proteins or stained with dyes are imaged while they grow using automatic movement of the ...
