Generic Workflow of a Highly Effective and Easy Anther Culture Method for Both Japonica and Indica Rice

Plants
As one of the most important staple crops in the world, rice plays a pivotal role in world food security. The creation of doubled haploids based on anther culture is an important technology for rice breeding.

A new microspore embryogenesis system under low temperature which mimics zygotic embryogenesis initials, expresses auxin and efficiently regenerates doubled-haploid plants in Brassica napus

BMC Plant Biology, 2012
Background Microspore embryogenesis represents a unique system of single cell reprogramming in plants wherein a highly specialized cell, the microspore, by specific stress treatment, switches its fate towards an embryogenesis pathway.

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.

Pseudo-embryogenic structures in anther and isolated microspore cultures in vitro: a cautionary guide

Czech Journal of Genetics and Plant Breeding, 2012
This review describes sources of structures of non-microspore origin observed in anther and microspore cultures. Various characteristics of these structures may cause a wrong diagnosis of these structures as embryos or cell/tissue clusters of microspore ...

Induction of embryogenesis in Brassica napus microspores produces a callosic subintinal layer and abnormal cell walls with altered levels of callose and cellulose

Frontiers in Plant Science, 2015
The induction of microspore embryogenesis produces dramatic changes in different aspects of the cell physiology and structure. Changes at the cell wall level are among the most intriguing and poorly understood.

Current insights into hormonal regulation of microspore embryogenesis

Frontiers in Plant Science, 2015
Plant growth regulator (PGR) crosstalk and interaction with the plant’s genotype and environmental factors play a crucial role in microspore embryogenesis (ME), controlling microspore-derived embryo differentiation and development as well as haploid ...

Dissecting meiotic recombination based on tetrad analysis by single-microspore sequencing in maize

Nature Communications, 2015
Meiotic recombination drives eukaryotic sexual reproduction and the generation of genome diversity. Tetrad analysis, which examines the four chromatids resulting from a single meiosis, is an ideal method to study the mechanisms of homologous ...

Viability of heat treated microspores of Cocos nucifera L. for induction of microspore embryogenesis

CORD
Tall coconut (Cocos nucifera L.) palm is an allogamous and highly heterozygous which is a major obstacle for conventional breeding. Microspore embryogenesis is a promising method which enables the development of homozygous lines. This study is conducted to detect the coconut microspore viability after heat treatment with different incubation periods ...
