Of the three types of ET, ET-1 is the most important in vascular tissue, and it acts on endothelin-A receptors on the vascular smooth muscle [ 48].
Inflorescence stems represent a developmental series with most recently derived vascular tissue present in apical regions of the stem and the oldest tissue in basal regions.
This review details the most recent developments on vascular tissue engineering, summarizes the results of initial experiments on animals and humans, and outlines the current status and the challenges for the future.
Among these meristems, the procambium and — in mature organs — the vascular cambium pervade the whole body of most vascular plants, giving rise to vascular tissues.
From this point of view, most plausible scenario for the vascular tissue expression of OsAP77 may be that OsAP77 accumulates in the extracellular space, sieve-tubes, where host proteins may be present, and functions as protease for processing possible target proteins/peptides into a signal peptide(s).
Four day-old 3x FORCA-pCAMBIA seedlings showed constitutive GUS activity in stems which is most pronounced in vascular tissues.
This expansion ultimately comes to a halt as the walls of some tissues, most notably the vascular tissues and supporting fibres, are reinforced with non-extensible secondary wall layers.
The PAPS3 promoter showed the most unique pattern, being most active in the cotyledon tips and vascular tissue of the radicle.
Auxin is transported downwards through the vascular tissue, reaching the most distal cells, the root cap.
PLT5 is expressed most strongly in roots but also in vascular tissue of leaves and in floral organs [ 34].
