Vitamin and zeatin treatments promote colchicine-induced haploid chromosome doubling in maize

open access: yesCrop Journal
Doubled haploid (DH) technology is an efficient method used in commercial maize breeding. Chromosome doubling is a vital step of DH technology; however, the underlying processes regulating chromosome doubling of haploid is still not well understood ...

Double-checking chromosome segregation

open access: yesJournal of Cell Biology, 2023
Enduring chromosome segregation errors represent potential threats to genomic stability due to eventual chromosome copy number alterations (aneuploidy) and formation of micronuclei—key intermediates of a rapid mutational process known as chromothripsis that is found in cancer and congenital disorders.

Research Progress of Chromosome Doubling and 2n Gametes of Ornamental Plants

open access: yesHorticulturae, 2023
Polyploid plants, an important source for the selection of ornamental plants for their advantages of faster growth, higher yields, and stronger adaptability to an adverse environment, play an essential role in the development of economic plants for ...

All nonhomologous chromosomes and rearrangements in Saccharum officinarum × Saccharum spontaneum allopolyploids identified by oligo-based painting

open access: yesFrontiers in Plant Science, 2023
Modern sugarcane cultivars (Saccharum spp., 2n = 100~120) are complex polyploids primarily derived from interspecific hybridization between S. officinarum and S. spontaneum.

Cytological study on haploid male fertility in maize

open access: yesJournal of Integrative Agriculture, 2022
Doubled haploid (DH) breeding technology, which relies on haploid genome doubling, is widely used in commercial maize breeding. Spontaneous haploid genome doubling (SHGD), a more simplified and straightforward method, is gaining popularity among maize ...

Double minute chromosomes are not centromeric regions of the host chromosomes [PDF]

open access: yesHereditas, 2009
The SEWA ascites tumor of the mouse contains, in addition to the ordinary chromosomes, a varying number of minute chromatin bodies, called double minutes (dms). Among 394 cells, 43 were without dms, the others had from 1 to 300 dms. The appearance of the dms suggested that they were acentric, which was also supported by the finding that even the ...

Gene count from target sequence capture places three whole genome duplication events in Hibiscus L. (Malvaceae)

open access: yesBMC Ecology and Evolution, 2021
Background The great diversity in plant genome size and chromosome number is partly due to polyploidization (i.e. genome doubling events). The differences in genome size and chromosome number among diploid plant species can be a window into the ...

Chromosome doubling in Paspalum notatum var. saure (cultivar Pensacola) [PDF]

open access: yesCrop Breeding and Applied Biotechnology, 2015
Paspalum notatum is one of the most important native grassland species of southern Brazil, and the main forage source for livestock. The native ecotypes are tetraploid and have apomictic reproduction, which prevents the registration and protection of ...

Improved efficiency of doubled haploid generation in hexaploid triticale by in vitro chromosome doubling

open access: yesBMC Plant Biology, 2012
Background Doubled haploid production is a key technology in triticale research and breeding. A critical component of this method depends on chromosome doubling, which is traditionally achieved by in vivo treatment of seedlings with colchicine.

Fertility recovery of anther-derived haploid plants in Cape gooseberry (Physalis peruviana L.)

open access: yesAgronomía Colombiana, 2018
The cape gooseberry (Physalis peruviana L.) is one of the most important Colombian exotic fruits. Chromosome doubling of anther-derived plants is a key factor in the application of double haploid technology for the genetic improvement of crops.
