1
Bacillus cereus is a ubiquitous, spore-forming bacterium associated with food poisoning cases.
2
Thus, our findings provide new mechanistic insight into C. difficile spore germination.
3
From egg to spore-mother-cell is sporophyte; from spore-mother-cell to egg is gametophyte.
4
A single spore would be enough to dissolve it and her story.
5
This last is what I alluded to as the summer spore stage.
1
The abnormal of those proceeding also lead to the production of 2n gamete.
2
Subsequently, such sperm RNA profiling could allow the molecular diagnosis of male gamete quality.
3
These phenomena directly lead to the production of 2n gamete.
4
Fertilization is the fusion of the male and female gamete.
5
Concurrently, these animals exhibit steadily worsening defects in gamete formation and function that ultimately lead to sterility.
6
We have observed a gamete-of-origin imprinting effect in C. elegans using a set of GFP reporter transgenes.
7
These complementary strategies are opening new avenues to determine how sperm ion channels function in gamete signaling.
8
The neuroendocrine regulation of GnRH secretion plays a central role in timing gamete release in both sexes.
9
L. Ectocarpus siliculosus, female gamete surrounded by male gametes a, b, c, d, e, stages of conjugation.
10
Yet the identity and function of these maternal factors during the gamete to embryo transition remains poorly understood.
11
The rationale for the use of artificial insemination is to increase gamete density at the site of fertilization.
12
These results show that ANK6 plays a central role in male-female gamete recognition, possibly by regulating mitochondrial gene expression.
13
The defect is genetically linked to an almost complete absence of male gamete production and of infectivity to mosquitoes.
14
In the reproductive zone, dense gamete clouds reduce visibility to zero over tens of metres along the shallow sea bed.
15
Double fertilization in angiosperms involves several successive steps, including guidance and reception of the pollen tube and male-female gamete recognition.
16
Usually, however, only one of the fusing cells is a zoogamete, the other gamete being a much larger resting cell.
