In plants, the chloroplast is the organelle that conducts photosynthesis. It has been known
that chloroplast is involved in virus infection of plants for approximate 70 years. Recently, the …

Sucrose (Suc) plays a central role in plant growth and development. It is a major end product
of photosynthesis and functions as a primary transport sugar and in some cases as a direct …

Plants viruses spread throughout their hosts using a number of pathways, the most common
being movement cell to cell through plasmodesmata (PD), unique intercellular organelles of …

Direct support for the concept that RNA molecules circulate throughout the plant, via the
phloem, is provided through the characterisation of mRNA from phloem sap of mature …

Salicylic acid (SA) treatment has recently been reported to inhibit replication of tobacco
mosaic virus (TMV) in inoculated tissue. Furthermore, resistance is induced via a novel …

Abstract Plant β-1, 3-glucanases are involved in plant defense and development. In rice
(Oryza sativa), 14 genes encoding putative β-1, 3-glucanases have been isolated and …

We report on the export capability and structural and ultrastructural characteristics of leaves
of the sucrose export defective1 (sed1; formerly called sut1) maize mutant. Whole-leaf …

The role played by plasmodesmata in the transport of viral infectious material in various leaf
tissues is reviewed under the headings: plasmodesmata exist as supramolecular structures; …

During multicellularization, plants evolved unique cell-cell connections, the plasmodesmata
(PD). PD of angiosperms are complex cellular domains, embedded in the cell wall and …

Due to their importance as crop species, solanaceous plants such as tobacco, potato and
tomato have been studied in great detail with respect to carbohydrate partitioning using …
