Lost Sex: The Evolutionary Biology of Parthenogenesis
4.2.1.6 Premeiotic Doubling This mode of automictic parthenogenesis involves
an endomitotic process: a premeiotic doubling of chromosome numbers is
reduced through meiosis. The resulting daughter chromosomes pair in the first
meiotic ...

INTERNATIONAL REVIEW OF CYTOLOGY
in Lilium is regularly preceded by either G2 of premeiotic interphase (Holm, 1977
) or a mitotic-like stage, considered to be a retarded premeiotic prophase,
resulting from some despiralization of chromosomes (Walters, 1970; Bennett and
Stern, ...

Nuclear Cytology in Relation to Development
Premeiotic chromosome doubling. As we have already seen, the chromosome
endoreduplication immediately preceding meiosis ensures the constant
formation of unreduced embryo sacs (and eggs) in the Allium nutans type of
apomictic ...

progression through ...

Research findings, “Among B-Type Cyclins Only CLB5 and CLB6 Promote
Premeiotic S Phase in Saccharomyces cerevisiae,” are discussed in a new report

Yeast as a Tool in Cancer Research
First, the S phase that occurs prior to meiosis (premeiotic S) is followed by two
successive rounds of chromosome segregation, rather than alternating between
S phase and mitosis. Second, the first meiotic division is reductional, resulting in
...

Boron in Plant and Animal Nutrition
During the critical period from premeiotic interphase to the young microspore,
biomass rapidly accumulates in anthers and the whole ear. The length of anthers
of the advanced florets increases from as little as 0.5 mm at the premeiotic stage
...

The Evolution of the Genome
B chromosome drive has been the subject of intensive research in many species.
Drive might occur at several stages during the life cycle, and can be premeiotic,
meiotic, or postmeiotic (for reviews, see Jones, 1991 and Camacho et al., 2000).

METHODS IN CELL BIOLOGY,VOLUME 11, YEAST CELLS
The mutants include variants blocked in premeiotic DNA synthesis (spo8 and
spo9), as well as a mutant exhibiting premeiotic DNA synthesis (spolO). Their
phenotypes may reflect defects in functions required only during nitrogen
starvation, ...

Yeast: Molecular and Cell Biology
Moreover, Clns downregulate levels of proteins involved in triggering meiosis,
such as Ime1p – a transcriptional activator of early genes involved in premeiotic
DNA replication, cross-overs and recombination. The negative regulation by Clns
