Autophagy is activated and involved in cell death with participation of cathepsins during stress-induced microspore embryogenesis in barley [PDF]

, 2018
Microspores are reprogrammed towards embryogenesis by stress. Many microspores die after this stress, limiting the efficiency of microspore embryogenesis. Autophagy is a degradation pathway that plays critical roles in stress response and cell death.

A new microspore embryogenesis system under low temperature which mimics zygotic embryogenesis initials, expresses auxin and efficiently regenerates doubled-haploid plants in Brassica napus

BMC Plant Biology, 2012
Background Microspore embryogenesis represents a unique system of single cell reprogramming in plants wherein a highly specialized cell, the microspore, by specific stress treatment, switches its fate towards an embryogenesis pathway.

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.

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 ...

Proteases with caspase 3-like activity participate in cell death during stress-induced microspore embryogenesis of Brassica napus

The EuroBiotech Journal, 2019
Microspore embryogenesis is a model system of plant cell reprogramming, totipotency acquisition, stress response and embryogenesis initiation. This in vitro system constitutes an important biotechnological tool for haploid and doubled-haploid plant ...

Stress-Induced Microspore Embryogenesis Requires Endogenous Auxin Synthesis and Polar Transport in Barley

Frontiers in Plant Science, 2019
Stress-induced microspore embryogenesis is a model in vitro system of cell reprogramming, totipotency acquisition, and embryo development. After induction, responsive microspores abandon their developmental program to follow an embryogenic pathway ...

Exogenous spraying of IAA improved the efficiency of microspore embryogenesis in Wucai (Brassica campestris L.) by affecting the balance of endogenous hormones, energy metabolism, and cell wall degradation

BMC Genomics, 2023
Background Microspore embryogenesis is an extraordinarily complicated process, comprehensively regulated by a composite network of physiological and molecular factors, among which hormone is one of the most crucial factors.

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.

Gametic and somatic embryogenesis through in vitro anther culture of different Citrus genotypes [PDF]

, 2015
: In vitro tissue culture represents a useful technique for advancing Citrus breeding and propagation. Among in vitro regeneration systems, anther culture is commonly used to produce haploids and doubled haploids for a fast-track producing homozygous ...
