Long-distance regulation of shoot gravitropism by Cyclophilin 1 in tomato (Solanum lycopersicum) plants
The phloem-mobile protein SlCyp1 traffics to distant parts of the shoot to regulate its gravitropic response. In addition, SlCyp1 targets specific cells in the root to promote lateral root development.

The effects of temperature and drought on autumnal senescence and leaf shed in apple under warm, east mediterranean climate
Autumnal senescence of apple in a warm climate corresponds to accumulated degree-days beneath 22 °C. Summer drought delays senescence and enables replenishment of carbohydrate reserves. Recover...

Macromolecules Trafficking in the Phloem and Interorgan Communication
The phloem is a major component of the vascular tissue responsible for the delivery of photoassimilates and nutrients from source (photosynthetically active) tissues to sink organs. The presence of active plas...

Signaling and Phloem-Mobile Transcripts
Numerous studies revealed that beside viral RNAs also plant endogenous RNAs are transported from source tissue towards apical tissues in plants. Surprisingly a high number of distinct transcripts including pro...

Movement of protein and macromolecules between host plants and the parasitic weed Phelipanche aegyptiaca Pers.
Little is known about the translocation of proteins and other macromolecules from a host plant to the parasitic weed Phelipanche spp. Long-distance movement of proteins between host and parasite was explored usin...

Melon phloem-sap proteome: developmental control and response to viral infection
In addition to small molecules such as sugars and amino acids, phloem sap contains macromolecules, including mRNA and proteins. It is generally assumed that all molecules in the phloem sap are on the move from...

Specific role of LeMAN2 in the control of seed germination exposed by overexpression of the LeMAN3 gene in tomato plants
Endo-β-mannanase is one of the key enzymes involved in the hydrolysis of the mannan-rich cell walls of tomato (Solanum lycopersicon) seeds. Two isoforms of endo-β-mannanase have been characterized in tomato seeds...

Determination of plant resistance to carbamate herbicidal compounds inhibiting cell division and early growth by seed and plantlets bioassays
Herbicide-resistant plants can be generated by either traditional breeding procedures or genetic engineering. Analyses of plant responses to a newly developed herbicide or the tolerance level of a newly develo...

Growth modulation of transgenic potato plants by heterologous expression of bacterial carbohydrate-binding module
Transgenic potato plants (Solanum tuberosum cv. Desiree) expressing the bacterial carbohydrate-binding module (CBM) family III, which is part of the Clostridium cellulovorans CBPA, under control of the CaMV 35S p...

Glyphosate inhibits the translocation of green fluorescent protein and sucrose from a transgenic tobacco host to Cuscuta campestris Yunk.
The parasitic plant Cuscuta campestris is dependent on its host for water, assimilates and amino acids. It can be controlled by the herbicide glyphosate, which inhibits 5-enolpyruvylshikimate-3-phosphate synthase...

Coexpression of the Soybean Vegetative Storage Protein β Subunit (S-VSPβ) Either with the Bacterial Feedback-Insensitive Dihydrodipicolinate Synthase or with S-VSPα Stabilizes the S-VSPβ Transgene Protein and Enhances Lysine Production in Transgenic Tobacco Plants
Soybean vegetative storage proteins (S-VSPs) are lysine-rich leaf proteins, originally found to accumulate to high levels in depodded soybean plants. In the present study, we overexpressed S-VSPβ, the ruminant...

Root-Directed Expression of Alien Genes in Transgenic Potato
Bacterial pathogens of potato, e.g. Pseudomonas solanacearum, are known to infect potato roots causing severe losses in relatively warm climates. Our intention was to express, in potato roots, a bactericidal pept...

Pleiotropic effects of tobacco-mosaic-virus movement protein on carbon metabolism in transgenic tobacco plants
Transgenic tobacco (Nicotiana tabacum L. cv. Xanthi) plants expressing wild-type or mutant forms of the 30-kDa movement protein of tobacco mosaic virus (TMV-MP) were employed to study the effects of the TMV-MP on...
