Artificial induction of chromosome-doubled highbush blueberries from pluripotent calli by trifluralin and colchicine

Technology in Horticulture
Artificial chromosome doubling of somatic cells enables the production of polyploid plants, which can then be employed in the breeding of novel varieties exhibiting superior traits.

Effectiveness of Colchicine in Inducing Polyploidy in 'Balady' Mandarin [PDF]

Journal of Plant Production
Lateral buds of potted mandarin plants (Citrus reticulata Balnco cv 'Balady') were treated with four concentrations of colchicine (0.0, 0.1, 0.5 and 1.0%) for five consecutive days in order to investigate colchicine effectiveness in producing tetraploid ...

Developmental, cytological and transcriptional analysis of colchicine-induced autotetraploid fruit derived from Actinidia chinensis cv. ‘Hongyang’

Scientia Horticulturae
‘Hongyang’ is the most widely cultivated red-fleshed diploid kiwifruit variety (Actinidia chinensis) in China. However, due to its relatively small fruit size, growers typically rely on the application of plant hormones to increase fruit size and yield ...

Morphological effects of induced polyploidy in Dendrobium nobile Lindl. (Orchidaceae)

Crop Breeding and Applied Biotechnology, 2014
In general, polyploidy in plants causes an increase in the size of vegetative structures. This work aimed to compare diploid plants (2n = 2 x = 38) and induced tetraploid plants (2n = 4 x = 76) of Dendrobium nobile Lindl. through the evaluation of the

Chromosome doubling effects of selected antimitotic agents in Brassica napus microspore culture

Czech Journal of Genetics and Plant Breeding, 2008
Effects of microspore culture treatment with antimitotic agents colchicine, trifluralin and oryzalin on the frequency of embryo formation, embryo development, plant regeneration and diploidization rate in three F1 hybrids of winter rapeseed cultivars ...

Characterization of in vitro haploid and doubled haploid Chrysanthemum morifolium plants via unfertilized ovule culture for phenotypical traits and DNA methylation pattern.

Frontiers in Plant Science, 2014
Chrysanthemum is one of important ornamental species in the world. Its highly heterozygous state complicates molecular analysis, so it is of interest to derive haploid forms.

The History of Chromosomal Instability in Genome-Doubled Tumors

Cancer Discovery
Abstract Tumors frequently display high chromosomal instability and contain multiple copies of genomic regions. Here, we describe Gain Route Identification and Timing In Cancer (GRITIC), a generic method for timing genomic gains leading to complex copy number states, using single-sample bulk ...

Dynamics of double strand breaks and chromosomal translocations

Molecular Cancer, 2014
Chromosomal translocations are a major cause of cancer. At the same time, the mechanisms that lead to specific chromosomal translocations that associate different gene regions remain largely unknown. Translocations are induced by double strand breaks (DSBs) in DNA.

The Variable Effect of Polyploidization on the Phenotype in Escallonia

Frontiers in Plant Science, 2018
To induce new variation within the Escallonia genus, chromosome doubling was performed in E. rubra, E. rosea, and E. illinita, three important species within this genus of mainly evergreen woody ornamental species.
