TL;DR: The results are interpreted as evidence for the presence of a transverse gradient system of (an) unknown cell-division factor(s) in the root cortex which may control the induction of cell divisions in nodule initiation brought about by the release of auxin and cytokinin from Rhizobium.

TL;DR: The results are consistent with the hypothesis that aj malicine accumulates by an ion-trap mechanism and that the accumulated ajmalicine is converted into serpentine inside the vacuoles.

TL;DR: Genome size (C values) and pollen viability staining were applied as new criteria to investigate the taxonomy of the genus Hosta Tratt and approximate the number of Hosta species that follows from the combined studies by Fujita (197618) on the Japanese species and Chung (1991 a11) onThe Korean species.

TL;DR: A simple non-invasive method for the characterization of growth of a plant cell suspension in a single culture flask using the dissimilation curves of sugars by a cell-culture, which can easily be related to other types of growth curves.

TL;DR: Cryopreserved cells proliferated after plating on solid medium and new cell suspensions could be initiated within 15 days and viable protoplasts could be obtained 15–21 days after thawing.
