Comparison of six different methods to calculate cell densities
Plant Methods, 2018 Background For in vitro culture of plant and animal cells, one of the critical steps is to adjust the initial cell density. A typical example of this is isolated microspore culture, where specific cell densities have been determined for different species.

Development of embryoids by microspore and anther cultures of red beet (Beta vulgaris L. subsp. vulgaris) [PDF]
Journal of Central European Agriculture, 2017 So far there is no information about receiving red beet androgenic embryos by androgenesis. Several factors were tested which affected this process: starch accumulation in microspores, correlation between bud length and microsporogenesis course ...

Proteomic variations after short-term heat shock treatment reveal differentially expressed proteins involved in early microspore embryogenesis in cabbage (Brassica oleracea) [PDF]
PeerJ, 2020 Microspore embryogenesis (ME), a widely used haploid breeding method that can considerably shorten the breeding cycle, provides an efficient mean of cultivating many important Brassica crops, such as cabbage, Chinese cabbage, and oilseed rape.

Androgenic response of Brazilian wheat genotypes to different pretreatments of spikes and to a gelling agent [PDF]
Pesquisa Agropecuária Brasileira, 2016 The objective of this work was to analyze the androgenic response of Brazilian wheat genotypes to different pretreatments of the spikes, prior to the culture of isolated microspores, and to the effect of a gelling agent in the induction culture medium ...

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.

Journal of Integrative Plant Biology, EarlyView.Plant Polyploidization via Gene Interference, a robust technology for inducing polyploidy in various rice accessions, uses transient RNAi‐mediated suppression of OSD1 to induce genomic duplication. Two strategies were used to directly induce fertile autotetraploid plants in the first generation, thereby substantially shortening the breeding cycle ...
