DME demethylation in the central and vegetative cells is also thought to produce small interfering RNAs (siRNA) that guide methylation at transposons in the egg and sperm cells, respectively.
The results describe a wide distribution of members of the putative redox regulated Cys-proteome in the central metabolism of both vegetative cells and heterocysts of N. punctiforme.
Studies in Arabidopsis and maize have identified two miRNAs that act sequentially in a pathway that is central to regulation of vegetative phase change (Wu and Poethig 2006; Chuck et al. 2007; Wu et al. 2009).
Some time later in female phase, but before anther opening (onset of male phase), the generative cell migrates to a central position in the vegetative (tube) cell, in close association with the tube cell nucleus.
The high coverage and differential regulation of proteins involved in several important biosynthetic pathways, within the core and heterocyst specific metabolism, indicate a wide distribution of redox-regulated thiols within the central metabolism of both vegetative cells and heterocysts of N. punctiforme.
RpoS and ppGpp are central to redirecting transcription between vegetative and stress/starvation states of E. coli and other bacteria, as summarized in figure 1.
She defined childhood schizophrenia as … pathology in behavior at every level and in every area of integration or patterning within the functioning of the central nervous system, be it vegetative, motor, perceptual, intellectual, emotional or social.
It is well established that the chloroplast plays a central role in the recovery of vegetative plants cells from desiccation [ 9] and it is possible that differences between the chloroplast genomes of T. ruralis and P. patens may relate to this fundamental difference between the two mosses.
The patient with central pontine myelinolysis lived in a persistent vegetative state for 2 years.
According to these results the central zone of the SAM in the vegetative stage can represent a stem-cell niche [ 37] which is activated after the floral induction for the developing floral bud [ 11].
