I found it often in literature that it's a neglected area but there is no reason why this is the case? Although tomato is a model organism for molecular biologists, much information is available on other stresses like heat stress and freezing tolerance but not on drought?
Dear Anber,
I dealt, in the past, with the drought stress tolerance in crops although not in tomatoes. But going over some specific literature, I remember the existence of some interesting works about this topic.
The reason why this aspect might be less indagate in tomatoes compared with other species might be due to the fact that tomatoes are often cultivated in greenhouses, other protected environments or in areas with high agronomic inputs, so the main breeding goals are related with pest diseases tolerance and qualitative characteristics.
But this is just a my opinion.
Best regards
Alessandro
might be that is difficult to get big fleshy fruits and long vines from interspecific crosses; small fruits and plants with overwintering fruit skin already exist. Cherry tomatoes and relative hybrids are on the market, but their resistance and skin thickness preclude industrial app. For research you may apply to http://www.kdcomm.net/~tomato/Tomato/ecomplx.html
I can say that the reason is because Tomato is usually grown under irrigation systems, and it is not exposed to problems of drought like other crops which grown in the marginal areas under rain fed conditions. so i may agree with the answer of Alessandro, however, some researcher try to genetically improve Tomato for the water use effciency to reduce cost of irrigations, since water became scarce, rather than improving drought tolerance of tomato per se.
