Salt resistance of tomato species grown in sand culture

Some Manganese-iron Relationships in Tomato Fruits Grown on Marl, Peat and Sand Soils

take as well as to the supply and uptake of calcium. Evans and Troxler (4) working with blossom-end rot, a physiological disorder of the tomato fruit, have indicated that or ganic acids may have an influence on calcium assimilation. Blossom-end rot seems to be similar to blackheart of celery in that calcium appears to be a limiting factor as associated with conditions similar to those associate...

Evaluation of Rapid Methods for Nitrate Plant Sap Analysis of Globe Artichoke Grown in Sand Culture

Artichoke has a high nitrogen requirements and often farmers apply excessive amounts of fertiliser that contributes to groundwater pollution by nitrate. Artichoke nitrogen fertilisation can be made more efficient by plant analysis. Petiole sap nitrate concentrations in recently mature leaves was tested as an indicator of crop nitrogen status in artichoke grown in sand culture. Two rapid methods...

Evolution of Disease Resistance Genes in Wild Tomato Species

Involvement of SlSOS2 in tomato salt tolerance

The Ca(2+)-dependent SOS pathway has emerged as a key mechanism in the homeostasis of Na(+) and K(+) under saline conditions. We recently identified and functionally characterized by complementation studies in yeast and Arabidopsis the gene encoding the calcineurin-interacting protein kinase of the SOS pathway in tomato, SlSOS2.(1) We also show evidences on the biotechnological potential of SlS...

Pyramiding of genes conferring resistance to Tomato yellow leaf curl virus from different wild tomato species

Tomato (Solanum lycopersicum) production in tropical and subtropical regions of the world is limited by the endemic presence of Tomato yellow leaf curl virus (TYLCV). Breeding programmes aimed at producing TYLCV-resistant tomato cultivars have utilized resistance sources derived from wild tomato species. So far, all reported breeding programmes have introgressed TYLCV resistance from a single w...
