Haploidy but not parthenogenetic activation leads to increased incidence of apoptosis in mouse embryos.
These plants were ignored during the green stem disorder evaluations because those symptoms were considered caused by factors not related to the cause of green stem disorder, such as late germination and plant emergence, systemic virus or mycoplasma-like organism infection, male-sterility, haploidy, or other causes.
It is thus desirable to approach the different routes leading to male-derived haploidy from an integrative point of view.
Moreover, since the genus is monophyletic (see, for example, Rowan and Powers, 1992; La-Jeunesse, 2001; Santos et at., 2002), our findings corroborate Blank's (1987) speculation that haploidy exists in S.
This is perhaps not surprising given that the haploidy of the males virtually eliminates the possibility for mechanisms of overdominance to maintain genetic polymorphism (Pamilo [TABULAR DATA FOR TABLE 6 OMITTED] et al.
The problem of haploidy. (Cytogenetic studies on Nicotiana haploids and their bearings to some other cytogenetic problems.).
He has structured an integrated protocol that uses cytogenetic manipulation, sexual haploidy, molecular diagnostics, and conventional/molecular cytology to generate unique wheat/alien chromosomal translocations targeted for scab resistance and salinity tolerance in bread wheat.
In the latter supposition especially, in those instances where successes have been achieved, it was only because haploidy or a single dominant gene was involved, there was straightforward expression of the trait in question, and there was adequate plating efficiency and plantlet recovery from the "cells" (Negrutiu et al., 1984).
Haploidy is favored when there is complete linkage or when mutations are either highly deleterious or partially dominant.
Comparisons of methods of haploid production and performance of wheat lines produced by doubled haploidy and single seed descent p.
Thus, haploidy forces asexual individuals to accept many types of mutations and DNA damage that can be corrected at least partially in a diploid setting.
As early as 1930, Aase stated: "Haploidy may be changed to diploidy in the meiotic division through non-reduction of univalents." Meiotic restitution is known to induce chromosome doubling and hence fertility in several interspecific and intergeneric hybrids of grasses (Maan and Sasakuma, 1977; Jauhar, 1993; Xu and Joppa, 1995).
