Cytological development, calcium dynamic and metabolite profile of stress-induced tobacco (Nicotiana tabacum L.) microspore under calcium chloride treatment [PDF]
Brazilian Journal of BiologyExogenous calcium is pivotal in activating microspore embryogenesis via calcium signaling. Altering the external calcium levels in the medium has been documented to impact the success rate of microspore embryogenesis initiation.

BnPME is progressively induced after microspore reprogramming to embryogenesis, correlating with pectin de-esterification and cell differentiation in Brassica napus [PDF]
, 2016 15 p.-9 fig.Background: Pectins are one of the main components of plant cell walls. They are secreted to the wall as highly methylesterified forms that can be de-esterified by pectin methylesterases (PMEs).

Effect of Heat Shock Treatment on Microspore Embryogenesis in Brassica oleracea Species
Journal of Agricultural Sciences, 2016 Heat shock treatments are widely used to induce microspore embryogenesis in Brassica species. In this study, the effect of high temperature treatment 32 °C and 35 °C for 2 days on microspore embryogenesis was investigated in six genotypes of Turkish ...

Changes in DNA methylation levels and nuclear distribution patterns after microspore reprogramming to embryogenesis in barley [PDF]
, 2014 26 p.-5 fig.The microspore can be induced in vitro, under specific stress treatments, to deviate from its gametophytic development and to reprogram towards embryogenesis, becoming a totipotent cell and forming haploid embryos which can further ...

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 ...

Cork oak microspore embryogenesis
, 2018 In vivo, the microspore inside the anther divides and follows the gametophytic program to form the mature pollen grain. In vitro, upon the application of a stress treatment the microspore can be deviated towards a proliferation process leading to ...
