Factoid Details

‘Embryos can be mutant.’

[⟨det (plur embryo.n)⟩ mutant.a]

Learned by Reading

In the ICWSM 2009 Weblog Corpus:

Embryos from mothers homozygous for a mutation in odd – 1 undergo what appears to be a normal set of events during most of their first embryonic mitosis, but at the end of the cell cycle the mutant embryos invariably fail to complete cytokinesis.
(Parse)

In the ICWSM 2009 Weblog Corpus:

In both mex – 2 and mex – 4 mutant embryos, the AB blastomere produces tissues similar to those normally generated by the EMS blastomere.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Furthermore, the organization of the actin, but not the microtubule cytoskeleton, is affected in ooc – 3 mutant embryos.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Preliminary data suggest that some or358 ts mutant embryos at the one – , two – and four – cell stages have microtubule nucleation defects, and in some embryonic cells microtubule nucleating centers appear dissociated from the nucleus.
(Parse)

In the ICWSM 2009 Weblog Corpus:

These mutant embryos fail to form a bipolar spindle in approximately 50 % of P0 cells.
(Parse)

In the ICWSM 2009 Weblog Corpus:

For example, mab – 22 mutant embryos at 25degC are usually arrested at late embryonic or early L1 stage.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Pronuclear migration is defective in spd – 5 mutant embryos, a mitotic spindle does not form, and the first cell division fails.
(Parse)

In the ICWSM 2009 Weblog Corpus:

In addition, zyg – 11 hypomorphic mutant embryos have a delay in meiosis II cell cycle progression.
(Parse)

In the ICWSM 2009 Weblog Corpus:

These two phenotypes are reminiscent of those that can be observed in zyg – 1 mutant embryos (O’ Connell & al.
(Parse)

In the ICWSM 2009 Weblog Corpus:

To determine what cytological defects are incurred by these mutants, the early divisions of mutant embryos produced at the restricted temperature are being recorded using a multi – focal plane time – lapse (4 – dimensional) recording system.
(Parse)

In the ICWSM 2009 Weblog Corpus:

When depleted of maternal gene activity, the mutant embryos display ventral enclosure defects similar to those seen in embryos completely lacking ced – 10 activity [5].
(Parse)

In the ICWSM 2009 Weblog Corpus:

Therefore all tested pharyngeal cell types (marginal, muscle and glands) of mutant embryos do not express specific markers.
(Parse)

In the ICWSM 2009 Weblog Corpus:

We find that neurons cultured from septin mutant embryos are defective in extension of processes, and that they display abnormalities in both their actin and microtubule cytoskeletons, suggesting that septins may regulate neuronal cytoskeleton assembly.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Immunofluorescence with antibodies to C. elegans yolk proteins YP88 and YP170 shows that the cytoplasmic vesicles that accumulate in cpl – 1 mutant embryos are enlarged yolk vesicles.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Many pod – 2 mutant embryos resemble par mutant embryos and show a loss of physical and developmental asymmetry at the one and two – cell stage.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Temperature – shift studies indicate that pod – 2 is required during oogenesis, indicating that aspects of embryonic polarization may precede fertilization. pod – 2 mutant embryos also exhibit a unique germline inheritance defect in which germline identity localizes to the wrong spot in the one – cell embryo and is therefore inherited by the wrong cell at the four – cell stage.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Our analysis of the membrane defects suggest that the ectopic membrane contractions observed in rfl – 1 mutant embryos might result from the initiation of multiple cleavage furrows during cytokinesis.
(Parse)

In the ICWSM 2009 Weblog Corpus:

Comparison of the proportions of mutant embryos at each developmental stage with the corresponding data for N2 embryos, however, shows that there is no significant difference between the time required to complete each phase in mutant and in wild type embryos, suggesting that starting these events does not require the normal completion of the preceding event.
(Parse)

In the ICWSM 2009 Weblog Corpus:

The phenotype of par – 6 mutant embryos is typical of par mutants in general.
