High Frequency Production of Doubled Haploid Rapeseed Plants by Direct Colchicine Treatment of Isolated Microspores

浙江大学学报. 农业与生命科学版, 2000
Techniques for microspore culture of Brassica napus have been improved rapidly, and embryogen-esis has been achieved in a wide range of genotypes. Plants regenerated from microspore-derived embryoids can be haploid, diploid or polyploid.

Anther and microspore cultures of barley and wheat [PDF]

, 1997
This paper briefly cites the various procedures for the production of doubled haploids in barley and wheat. Various associated terms are defined and the factor involved in haploid production are outlined. Isolated microspore cultures offer some advantages over anther culture.

Chromosome doubling of microspore-derived plants from cabbage (Brassica oleracea var. capitata L.) and broccoli (Brassica oleracea var. italica L.)

Frontiers in Plant Science, 2015
Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high ...

TRADITION, QUALITY AND BIOTECHNOLOGY IN HUNGARIAN SPICE PEPPER (Capsicum annuum L.) BREEDING [PDF]

, 2010
Spice pepper production has a history of almost 300 years in the southern part of Hungary. In this study the results of two biotechnological improvements are summarized. Anther and isolated microspore culture techniques were improved to release haploid

Effects of Genotype and Culture Conditions on Microspore Embryogenesis and Plant Regeneration in Brassica Rapa ssp. Rapa L.

Plants, 2020
Turnip is a biennial crop and, consequently, the creation of pure lines for breeding is a time-consuming process. The production of pure turnip lines using doubled haploids produced in isolated microspore culture has not been sufficiently developed.

Effect of ovary induction on bread wheat anther culture: ovary genotype and developmental stage, and candidate gene association.

Frontiers in Plant Science, 2015
Ovary pre-conditioned medium and ovary co-culture increased the efficiency of green doubled haploid plant production in bread wheat anther culture. The positive effect of this medium led to a 6- and 11-fold increase in the numbers of embryos and green ...

Efficient Production of Doubled Haploid Plants through Microspore Culture in Brassica napus

浙江大学学报. 农业与生命科学版, 2000
Since haploid embryoids were first obtained from microspore culture of Brassica napus there has been a rapid progress in the application of this technique in genetic studies and breeding utilization of rapeseed.

Transcriptomics integrated with metabolomics reveals the effect of cold stress on rice microspores

BMC Plant Biology, 2023
Background Microspore culture is one of the important biotechnological tools in plant breeding. The induction of microspore embryogenesis is a critical factor that affects the yield of microspore-derived embryo productions.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.
