Plant sex chromosome evolution
Journal of Experimental Botany, 2012It is now well established that plants have an important place in studies of sex chromosome evolution because of the repeated independent evolution of separate sexes and sex chromosomes. There has been considerable recent progress in studying plant sex chromosomes.

Sex Chromosomes in Land Plants
Annual Review of Plant Biology, 2011Sex chromosomes in land plants can evolve as a consequence of close linkage between the two sex determination genes with complementary dominance required to establish stable dioecious populations, and they are found in at least 48 species across 20 families. The sex chromosomes in hepatics, mosses, and gymnosperms are morphologically heteromorphic.

Analysis of Plant Meiotic Chromosomes by Chromosome Painting
2013Chromosome painting (CP) refers to visualization of large chromosome regions, entire chromosome arms, or entire chromosomes via fluorescence in situ hybridization (FISH). For CP in plants, contigs of chromosome-specific bacterial artificial chromosomes (BAC) from the target species or from a closely related species (comparative chromosome painting, CCP)

C-Banding of Plant Chromosomes
2023C-banding visualizes regions of chromosomes containing constitutive heterochromatin. It creates distinct patterns along the chromosome length and allows precise chromosome identification if C-bands are present in sufficient numbers. It is performed on chromosome spreads generated from fixed material, usually root tips or anthers.

Genome, 1989
Chromosome banding was first discovered by Darlington and his then assistant, La Cour, in 1938. Their technique consisted essentially of keeping the living material at low temperature for a given time, followed by conventional staining. Thirty years later, the second very significant breakthrough was made by Caspersson and his co-workers (1968) who ...

Synthetic Chromosome Platforms in Plants
Annual Review of Plant Biology, 2012Synthetic chromosomes provide the means to stack transgenes independently of the remainder of the genome. Combining them with haploid breeding could provide the means to transfer many transgenes more easily among varieties of the same species. The epigenetic nature of centromere formation complicates the production of synthetic chromosomes.

Uptake of isolated plant chromosomes by plant protoplasts
Planta, 1981For mass isolation of plant metaphase chromosomes, cultured cells of wheat (Triticum monococcum) and parsley (Petroselinum hortense) were synchronized by hydroxyurea and colchicine treatment. This synchronization procedure resulted in high mitotic synchrony, especially in suspension cultures of parsley in which 80% of the cells were found to be at the ...

Chromosome Painting for Plant Biotechnology
2010Fluorescence in situ hybridization (FISH) is an invaluable tool for chromosome analysis and engineering. The ability to visually localize endogenous genes, transposable elements, transgenes, naturally occurring organellar DNA insertions - essentially any unique sequence larger than 2 kb - greatly facilitates progress.

Chromosomal organization of the genomes of small-chromosome plants
Russian Journal of Genetics, 2009An effective approach to study the chromosome organization in genomes of plants with small chromosomes and/or with low-informative C-banding patterns was developed in the course of investigation of the karyotypes of cotton plant, camomile, flax, and pea. To increase the resolving power of chromosome analysis, methods were worked out for revealing early
