Anomalous pollen grain development after nondifferentiating microspore division in Eremurus

open access: yesActa 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.

The effect of copper on plant regeneration in barley microspore culture

open access: yesCzech Journal of Genetics and Plant Breeding, 2017
Isolated microspore culture is an excellent system for the production of doubled haploids in many crops, including barley. In a more traditional barley anther culture method copper sulphate is known to enhance plant regeneration.

Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth [PDF]

open access: yes, 2005
Background: Callose (β-1,3 glucan) separates developing pollen grains, preventing their underlying walls (exine) from fusing. The pollen tubes that transport sperm to female gametes also contain callose, both in their walls as well as in the plugs that ...

Proteases with caspase 3-like activity participate in cell death during stress-induced microspore embryogenesis of Brassica napus

open access: yesThe EuroBiotech Journal, 2019
Microspore embryogenesis is a model system of plant cell reprogramming, totipotency acquisition, stress response and embryogenesis initiation. This in vitro system constitutes an important biotechnological tool for haploid and doubled-haploid plant ...
