Diverse Traits Contribute to Salinity Tolerance of Wild Tomato Seedlings from the Galapagos Islands.

Traits of modern crops have been heavily selected in agriculture, leaving commercial lines often more susceptible to harsh conditions compared with their wild relatives. Understanding the mechanisms of stress tolerance in wild relatives can enhance crop performance under stress conditions such as high salinity. In this study, we investigated salinity tolerance of two species of wild tomato endemic to the Galapagos Islands, and Since these tomatoes grow well despite being constantly splashed with seawater, they represent a valuable genetic resource for improving salinity tolerance in commercial tomatoes.

[Amyotrophic lateral sclerosis syndrome of syphilitic origin. 5 cases].

We studied 5 cases of syphilitic lateral amyotrophic sclerosis. The diagnosis was based on the presence of a lymphocytic reaction in the CSF and positive VDRL and TPHA reactions in both blood and CSF. Clinically, the disease affected the arms in 3 cases and produced paraplegia in 2 cases.
