Influence of crop load on the expression patterns of starch metabolism genes in alternate-bearing citrus trees.

The fruit is the main sink organ in Citrus and captures almost all available photoassimilates during its development. Consequently, carbohydrate partitioning and starch content depend on the crop load of Citrus trees. Nevertheless, little is known about the mechanisms controlling the starch metabolism at the tree level in relation to presence of fruit.

Differences in photosynthetic performance and its correlation with growth among tomato cultivars in response to different salts.

Previous works into photosynthesis regulation under salt stress have focused on the effect of NaCl, although other salts may significantly contribute to the toxicity of saline soils. In this paper, the effects of different salt sources (NaCl, Na(2)SO(4), MgCl(2) and MgSO(4)) on photosynthesis and vegetative growth in three tomato (Solanum lycopersicum L.) cultivars (Marmande RAF, Leader and Daniela) are presented.

A survey of genes differentially expressed during long-term heat-induced chilling tolerance in citrus fruit.

Long-term storage at low, non-freezing, temperature (1.5 degrees C) induces chilling injury in fruit of Fortune mandarin (Citrus clementina Hort. Ex Tanaka x Citrus reticulata, Blanco), manifested as pitting and brown depressed areas that may end up with local cell death.
