Induction of pollen embryo and chromosome doubling in tobacco (Nicotianatabacum L.)

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Doubled haploid production from Spanish onion (Allium cepa L.) germplasm: embryogenesis induction, plant regeneration and chromosome doubling

The use of doubled haploids in onion breeding is limited due to the low gynogenesis efficiency of this species. Gynogenesis capacity from Spanish germplasm, including the sweet cultivar Fuentes de Ebro, the highly pungent landrace BGHZ1354 and the two Valenciana type commercial varieties Recas and Rita, was evaluated and optimized in this study. The OH-1 population, characterized by a high gyno...

I-38: Chromosome Instability in The Cleavage Stage Embryo

Recently, we demonstrated chromosome instability (CIN) in human cleavage stage embryogenesis following in vitro fertilization (IVF). CIN not necessarily undermines normal human development (i.e. when remaining normal diploid blastomeres develop the embryo proper), however it can spark a spectrum of conditions, including loss of conception, genetic disease and genetic variation development. To s...

Induction of chromosome doubling at meiosis by the elongate gene in maize.

EIOSIS is a highly integrated system characterized by the orderly procession of events such as pairing, recombination, chiasma formation, and disjunction, which culminates in a reduction o€ chromosome number in the gametes. That this system is under genic control has long been evident from the many mutant genes reported in plants and animals which affect specific stages of the meiotic system. T...
