Calcium and cell wall dynamics during microspore embryogenesis and double haploid production in rapeseed and eggplant

Rivas Sendra, Alba (Universitat Politècnica de València, 2017-07-20)

Androgenesis induction is an experimental procedure by which microspores are diverted from their original gametophytic pathway towards embryogenesis by applying specific stresses in vitro. It allows for the production of ...

Dynamics of calcium during in vitro microspore embryogenesis and in vivo microspore development in Brassica napus and Solanum melongena

Rivas-Sendra, Alba; Calabuig-Serna, Antonio; Seguí-Simarro, Jose M. (Frontiers Media SA, 2017)

[EN] Calcium is widely known to have a role as a signaling molecule in many different processes, including stress response and activation of the embryogenic program. However, there are no direct clues about calcium levels ...
Effects of growth conditions of donor plants and in vitro culture environment in the viability and the embryogenic response of microspores of different eggplant genotypes

Rivas-Sendra, Alba; Corral Martínez, Patricia; Camacho-Fernández, Carolina; Porcel, R; Seguí-Simarro, Jose M. (Springer-Verlag, 2020-10-06)

[EN] Notwithstanding the importance of eggplant in global horticulture, doubled haploid production in this species is still far from being efficient. Although acknowledged to have a role in the efficiency of androgenesis ...
Embryogenic competence of microspores is associated to their ability to form a callosic, osmoprotective subintinal layer

Rivas-Sendra, Alba; Corral Martínez, Patricia; Porcel, R.; Camacho-Fernández, Carolina; Calabuig-Serna, Antonio; Seguí-Simarro, Jose M. (Oxford University Press, 2019-02-01)

[EN] Microspore embryogenesis is an experimental morphogenic pathway with important applications in basic research and applied plant breeding, but its genetic, cellular, and molecular bases are poorly understood. We applied ...
Estudio del efecto del alcohol bencílico en la inducción de androgénesis

Mata Nicolás, Estefanía (Universitat Politècnica de València, 2016-11-29)

[EN] Obtaining double haploid plants is a powerful tool for breeding programs, because these plants are 100% homozygous. These pure lines can be used as parental lines, allowing for the production of ...
Estudio histológico del efecto de la aplicación de tricostatina durante la inducción de embriogénesis en microsporas de Brassica napus

Albiñana Palacios, Mireia (Universitat Politècnica de València, 2017-01-02)

[EN] Microspore culture is a useful tool to produce doubled haploid individuals for plant breeding in a way cheaper and faster than through conventional crosses. This technique has been studied in many species and ...
Formation and excretion of autophagic plastids (plastolysomes) in Brassica napus embryogenic microspores

Parra Vega, Verónica; Corral Martínez, Patricia; Rivas-Sendra, Alba; Seguí-Simarro, Jose M. (Frontiers Media, 2015-02)

[EN] The change in developmental fate of microspores reprogrammed toward embryogenesis is a complex but fascinating experimental system where microspores undergo dramatic changes derived from the developmental switch. ...
Improved regeneration of eggplant doubled haploids from microspore-derived calli through organogenesis

Rivas Sendra, Alba; Corral Martínez, Patricia; Camacho Fernández, Carolina; Seguí-Simarro, Jose M. (Springer Verlag (Germany), 2015-09)

[EN] Doubled haploid (DH) technology allows for the production of pure lines, useful for plant breeding, through a one-generation procedure that reduces considerably the time and resources needed to produce them. ...
Induction of embryogenesis in Brassica napus microspores produces a callosic subintinal layer and abnormal cell walls with altered levels of callose and cellulose

Parra Vega, Verónica; Corral Martínez, Patricia; Rivas-Sendra, Alba; Seguí-Simarro, Jose M. (Frontiers Media, 2015-11-25)

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. In this ...
