In Situ Detection of nDNA Fragmentation during the Differentiation of Tracheary Elements in Higher Plants.
Programmed cell death (pcd) is thought to occur during the autolysis of xylem vessels. Although several ultrastructural aspects of this differentiation process have been characterized, certain key aspects of this process remain unsolved. Here we demonstrate in pea (Pisum sativum) that nuclei of vessel elements undergoing pcd contain fragmented nDNA. This finding may provide evidence for the act...
متن کاملMolecular basis of cell recognition during fertilization in higher plants.
The molecular basis of recognition between plant cells is incompletely understood. Some principles established for recognition between animal cells may well apply to plant cell recognition, although, in contrast to animal cells, plant cells are encased by cell walls that play an active role in plant cell-cell recognition. The interaction that controls fertilization in flowering plants involves ...

متن کاملSelenium in Higher Plants.
Plants vary considerably in their physiological response to selenium (Se). Some plant species growing on seleniferous soils are Se tolerant and accumulate very high concentrations of Se (Se accumulators), but most plants are Se nonaccumulators and are Se-sensitive. This review summarizes knowledge of the physiology and biochemistry of both types of plants, particularly with regard to Se uptake ...
متن کاملPollen-specific gene expression in transgenic plants: coordinate regulation of two different tomato gene promoters during microsporogenesis.
To investigate the regulation of gene expression during male gametophyte development, we analyzed the promoter activity of two different genes (LAT52 and LAT59) from tomato, isolated on the basis of their anther-specific expression. In transgenic tomato, tobacco and Arabidopsis plants containing the LAT52 promoter region fused to the beta-glucuronidase (GUS) gene, GUS activity was restricted to...
