5-azacytidine promotes microspore embryogenesis initiation by decreasing global DNA methylation, but prevents subsequent embryo development in rapeseed and barley [PDF]
Frontiers in Plant Science, 2015 Microspores are reprogrammed by stress in vitro towards embryogenesis. This process is an important tool in breeding to obtain double-haploid plants. DNA methylation is a major epigenetic modification that changes in differentiation and proliferation. We

Current insights into hormonal regulation of microspore embryogenesis [PDF]
Frontiers in Plant Science, 2015 Plant growth regulator (PGR) crosstalk and interaction with the plant’s genotype and environmental factors play a crucial role in microspore embryogenesis (ME), controlling microspore-derived embryo differentiation and development as well as haploid ...

Microspore embryogenesis in vitro: the role of stresses
Вавиловский журнал генетики и селекции, 2019 Gametic embryogenesis is one form of totipotency of plant cells, in which either male or female gametes are induced to form embryoids (sporophytes). Regeneration of haploid plants from embryoids and subsequent chromosome duplication result in doubled ...

Effect of temperature shock on soybean microspore embryogenesis [PDF]
Brazilian Archives of Biology and Technology, 2004 In this study the effect of cold and heat shock on androgenetic induction in soybean anther culture was tested. Anthers of soybean were subjected to 4 and 33ºC, while the anthers used for control were maintained at 25ºC.

EMBRYOGENESIS IN CULTURE OF ISOLATED MICROSPORE OF BROCCOLI
Овощи России, 2018 The process of embryogenesis and technological experimental protocol has been studied and applied to produce doubled haploid plants from microspore cultured in vitro in broccoli B. oleracea L. convar. botrytis (L.) Alef. var. italica Plenck. It was shown

Impact of Ionic Liquids on Induction of Wheat Microspore Embryogenesis and Plant Regeneration
Agronomy, 2020 Ionic liquids are novel compounds with unique chemical and physical properties. They can be received based on synthetic auxins like 2,4-dichlorophenoxyacetic acid or dicamba, which are commonly used hormones in microspore embryogenesis.

Microspore embryogenesis in Apiaceae
Plant Cell, Tissue and Organ Culture (PCTOC), 2010 Haploid technology is used to develop uniform, true-breeding lines, as well as to accelerate crop improvement programs. Among 20 Apiaceae species screened for response to doubled haploidy, 11 generated microspore-derived embryos, and all but one of the latter yielded doubled haploid plants.

Transcriptomics integrated with metabolomics reveals the effect of cold stress on rice microspores
BMC Plant Biology, 2023 Background Microspore culture is one of the important biotechnological tools in plant breeding. The induction of microspore embryogenesis is a critical factor that affects the yield of microspore-derived embryo productions.

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.
