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.

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 ...

Inhibition of Histone H3K9 Methylation by BIX-01294 Promotes Stress-Induced Microspore Totipotency and Enhances Embryogenesis Initiation

Frontiers in Plant Science, 2017
Microspore embryogenesis is a process of cell reprogramming, totipotency acquisition and embryogenesis initiation, induced in vitro by stress treatments and widely used in plant breeding for rapid production of doubled-haploids, but its regulating ...

Semi-thin Sectioning, Light and Fluorescence Microscopy of Floral Bud to Study Microspore Development in Arabidopsis

Bio-Protocol, 2016
Pollen grains are male gametophytes produced within the pollen sacs of the anthers of the flower. Recent genetic studies have revealed several components involved in microspore development (Borg et al., 2009; Berger and Twell, 2011), and yet many ...

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 ...

Anomalous pollen grain development after nondifferentiating microspore division in Eremurus

Acta Societatis Botanicorum Poloniae, 2015
Anomalous pollen grain development in Eremurus is caused by an anomalous position of the mitotic spindle and microspore protoplast division into two cells different than in differentiating division.

Nuclear bodies domain changes with microspore reprogramming to embryogenesis

European Journal of Histochemistry, 2009
We analysed the presence of nuclear bodies and particularly Cajal bodies during representative stages of gametophytic and haploid embryogenic development in isolated microspore and anther cultures of a model system (Brassica napus cv.
