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.

Androgenesis induction in microspore culture of sweet pepper (Capsicum annuum L.) [PDF]

, 2011
Isolated microspore culture experiments were carried out in sweet pepper (Capsicum annuum L.) F1 hybrid genotypes. In the first experiment, four culture media (W14, B5, MS and NLN) were compared to test their effectiveness in inducing the formation ...

Early embryo achievement through isolated microspore culture in Citrus clementina Hort. ex Tan., cvs. ‘Monreal Rosso’ and ‘Nules’

Frontiers in Plant Science, 2015
Microspore embryogenesis is a method of achieving complete homozygosity from plants. It is particularly useful for woody species, like Citrus, characterized by long juvenility, a high degree of heterozygosity and often self-incompatibility.

5-azacytidine promotes microspore embryogenesis initiation by decreasing global DNA methylation, but prevents subsequent embryo development in rapeseed and barley

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

Induction of embryogenesis in Brassica napus microspores produces a callosic subintinal layer and abnormal cell walls with altered levels of callose and cellulose

Frontiers in Plant Science, 2015
The induction of microspore embryogenesis produces dramatic changes in different aspects of the cell physiology and structure. Changes at the cell wall level are among the most intriguing and poorly understood.

Identification, Gene Structure, and Expression of BnMicEmUP: A Gene Upregulated in Embryogenic Brassica napus Microspores

Frontiers in Plant Science, 2021
Microspores of Brassica napus can be diverted from normal pollen development into embryogenesis by treating them with a mild heat shock. As microspore embryogenesis closely resembles zygotic embryogenesis, it is used as model for studying the molecular ...

The Roads to Haploid Embryogenesis

Plants, 2023
Although zygotic embryogenesis is usually studied in the field of seed biology, great attention has been paid to the methods used to generate haploid embryos due to their applications in crop breeding.

Effects of altered expression of LEAFY COTYLEDON1 and FUSCA3 on microspore-derived embryogenesis of Brassica napus L.

Journal of Genetic Engineering and Biotechnology, 2016
Brassica napus (Bn) microspore-derived embryogenesis has become a model system to study basic aspects of plant development. Recognized transcription factors governing embryogenesis include: FUSCA3 (FUS3), a member of the plant-specific B3-domain family ...

Effect of ovary induction on bread wheat anther culture: ovary genotype and developmental stage, and candidate gene association.

Frontiers in Plant Science, 2015
Ovary pre-conditioned medium and ovary co-culture increased the efficiency of green doubled haploid plant production in bread wheat anther culture. The positive effect of this medium led to a 6- and 11-fold increase in the numbers of embryos and green ...

TRADITION, QUALITY AND BIOTECHNOLOGY IN HUNGARIAN SPICE PEPPER (Capsicum annuum L.) BREEDING [PDF]

, 2010
Spice pepper production has a history of almost 300 years in the southern part of Hungary. In this study the results of two biotechnological improvements are summarized. Anther and isolated microspore culture techniques were improved to release haploid
