[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 ...
Enhancing secondary embryogenesis in Brassica napus by selecting hypocotyl-derived embryos and using plant-derived smoke extract in culture medium

Abdollahi, M.R.; Ghazanfari, P.; Corral Martínez, Patricia; Moieni, A.; Seguí-Simarro, Jose M. (Springer Verlag (Germany), 2012-08)

Induction of secondary embryogenesis on transformed androgenic microspore-derived embryos (MDEs) is a convenient approach to avoid chimerism and hemizygosis for the introduced transgene. In this work, we improved two aspects ...
Estudio sobre alternativas de cultivo para el periodo otoñal-invernal en la zona arrocera de Valencia

García Marín, Carlos (Universitat Politècnica de València, 2020-10-01)

[ES] El arroz es un cultivo tradicional en la zona valenciana, que se cultiva en monocultivo. Terminado el ciclo productivo del cultivo, los arrozales se mantienen inundados, es decir, tras la cosecha que termina en octubre, ...
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. ...
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 ...
