Automated Tracking of Root for Confocal Time-lapse Imaging of Cellular Processes
[Abstract]  Here we describe a protocol that enables to automatically perform time-lapse imaging of growing root tips for several hours. Plants roots expressing fluorescent proteins or stained with dyes are imaged while they grow using automatic movement of the microscope stage that compensates for root growth and allows to follow a given region of the root over time. The protocol makes possible the image acquisition of multiple growing root tips, therefore increasing the number of recorded mitotic events ...

Stress Tolerance Assay at the Seed Germination Stage for Tobacco
[Abstract]  Stress tolerance of plants is a complex phenomenon that depends on the inter-related action of several morphological, physiological and biochemical parameters. Although stress affects normal physiological growth of a plant irrespective of its developmental stage, seed germination and seed setting are considered to be the most sensitive two. Therefore, to evaluate the stress tolerance potential of a particular plant species or variety, rate of seed germination in presence of stress is an ...
