The effect of copper on plant regeneration in barley microspore culture

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 …

Genome-wide association study for anther length in some elite bread wheat germplasm

The anther is a crucial organ for the development of the spike in bread wheat (Triticum aestivum L.). Long anthers contain large amounts of pollen grains; thus, they are favourable for …

Effects of spring low-temperature stress on winter wheat seed-setting characteristics of spike

Global climate change leads to frequent occurrence of low-temperature stress (LTS), which poses a serious threat to global food security. Here, environment-control phytotron experiments were conducted …

Early in vitro selection of winter oilseed rape (Brassica napus L.) plants with the fertility restorer gene for CMS Shaan 2A via non-destructive molecular analysis of microspore-de...

Cotyledons of 201 microspore-derived oilseed rape (Brassica napus) embryos were analysed for the presence of the cytoplasmic male sterility Shaan 2A restorer gene using the primer pair 3F/4R. In …

Morphological variation of male A. arguta plants affects their flowering potential and pollen efficiency

Actinidia arguta (Siebold et Zucc.) Planch. ex Miq. is functionally a cryptic dioecious plant and successful pollination is crucial for achieving high quality fruit. The extent and bases of …

TPR domain coding gene ST2 may be involved in regulating tillering and fertility in rice

A decrease in the tiller number and male sterility will lead to a decline in the rice yield. Therefore, it is significant to study the molecular mechanism of controlling the tiller number and …

Cytological investigation of anther development in DGMS line Shaan-GMS in Brassica napus L.

The cytological mechanism of male sterility of Shaan-GMS, a natural mutant dominant genic male sterile (DGMS) line in Brassica napus, is not well studied. Cytological observation was made on …

Obtaining calli and regenerated plants in anther cultures of pea

Pea (Pisum sativum L.) is a species for which there is no efficient method for the recovery of haploid plants yet. This research investigated the influence of various genotypes, nutrient media, and …

Species of the genus Meligethes occurring in oil-seed crop fields in the Czech Republic

Identification of Meligethes species and their frequencies in adult samples collected at different localities in Central and South Moravia (Czech Republic, 2009-2011) was based on comparisons of …

A 31-bp indel localised in the 5' untranslated region of OsSUT3 affects the gene expression and rice (Oryza sativa L.) pollen development

OsSUT genes have been demonstrated to be relevant for diverse biological processes in rice. In this study, we identified the close relationship between a 31-bp insertion in a 5' untranslated …

Predikce výskytu klasových fuzárií na základě sledování tvorby infekčních struktur patogena na kukuřičných posklizňových zbytcích = Prediction of Fusarium head blight occurence bas...

V letech 2019–2021 byla hodnocena přítomnost perithecií, jejich četnost a tvorba askospor na posklizňových zbytcích kukuřice. Rostlinný materiál byl sbírán z povrchu půdy s obilninami …
