Pericycle

چکیده
And what lessons could other countries learn from Finland? A major difference, when compared, for example, to central and southern Europe, is gender equality. For decades, Finnish women have had their jobs outside home, and this has been supported by the state: we have an excellent and affordable communal day-care system and equal high-quality basic education systems. Being a woman has not hindered my scientific career. However, I notice the difference, when I travel south. A concrete example: I was interviewed for the Centre of Excellence call when 8 months pregnant. A German colleague said that she would never have passed the interview in her country, looking so pregnant. It did not even occur to me that my physical appearance or life situation would somehow affect the outcome of my interview. It did not. We were selected for Centre of Excellence of the Academy of Finland.

Transcriptomic and proteomic analyses of pericycle cells of the maize primary root.
Each plant cell type expresses a unique transcriptome and proteome at different stages of differentiation dependent on its developmental fate. This study compared gene expression and protein accumulation in cell-cycle-competent primary root pericycle cells of maize (Zea mays) prior to their first division and lateral root initiation. These are the only root cells that maintain the competence to...
متن کاملDiarch symmetry of the vascular bundle in Arabidopsis root encompasses the pericycle and is reflected in distich lateral root initiation.
The outer tissues of dicotyledonous plant roots (i.e. epidermis, cortex, and endodermis) are clearly organized in distinct concentric layers in contrast to the diarch to polyarch vascular tissues of the central stele. Up to now, the outermost layer of the stele, the pericycle, has always been regarded, in accordance with the outer tissue layers, as one uniform concentric layer. However, conside...
متن کاملAuxin-mediated cell cycle activation during early lateral root initiation.
Lateral root formation can be divided into two major phases: pericycle activation and meristem establishment. In Arabidopsis, the first lateral root initiation event is spatially and temporally asynchronous and involves a limited number of cells in the xylem pericycle. To study the molecular regulation during pericycle activation, we developed a lateral root-inducible system. Successive treatme...
متن کاملVery-long-chain fatty acids restrict regeneration capacity by confining pericycle competence for callus formation in Arabidopsis.
The already differentiated organs in plants have a remarkable capacity to regenerate new individuals under culture conditions. Plant in vitro regeneration practically starts with the induction of a pluripotent cell mass, the callus, from detached organs on auxin-rich callus-inducing medium (CIM), which is generally required for subsequent regeneration of new bodies. Recent studies show that CIM...
متن کاملIn silico analyses of pericycle cell populations reinforce their relation with associated vasculature in Arabidopsis.
In Arabidopsis, lateral root initiation occurs in a subset of pericycle cells at the xylem pole that will divide asymmetrically to give rise to a new lateral root organ. While lateral roots never develop at the phloem pole, it is unclear how the interaction with xylem and phloem poles determines the distinct pericycle identities with different competences. Nevertheless, pericycle cells at these...
متن کاملPhloem-associated auxin response maxima determine radial positioning of lateral roots in maize.
In Arabidopsis thaliana, lateral-root-forming competence of pericycle cells is associated with their position at the xylem poles and depends on the establishment of protoxylem-localized auxin response maxima. In maize, our histological analyses revealed an interruption of the pericycle at the xylem poles, and confirmed the earlier reported proto-phloem-specific lateral root initiation. Phloem-p...
