AB  - Water deficit triggers physiological, biochemical, and molecular changes in leaves that could be important for overall plant adaptive response and it can affect
tomato yield and quality. To assess the influence of longterm moderate drought on leaves, four tomato accessions
from MAGIC TOM populations were selected on the basis
of their differences in fruit size and were grown in a
glasshouse under control and water deficit conditions.
Drought affected stomatal conductance more in large fruit
genotypes compared to cherry genotypes and this could be
related to higher abscisic acid (ABA) leaf content. Compared to large fruits, cherry tomato genotypes coped better
with water stress by reducing leaf area and maintaining
photochemical efficiency as important adaptive responses.
Accumulation of soluble sugars in the cherry genotypes
and organic acid in the leaves of the larger fruit genotypes
indicated their role in the osmoregulation and the continuum of source/sink gradient under stress conditions. Longterm moderate drought induced upregulation of NCED
gene in all four genotypes that was associated with ABA
production. The increase in the expression of ZEP gene
was found only in the LA1420 cherry genotype and indicated its possible role in the protection against photooxidative stress induced by prolonged water stress. In
addition, upregulation of the APX genes, higher accumulation of vitamin C and total antioxidant capacity in cherry
genotype leaves highlighted their greater adaptive response
against long-term drought stress compared to larger fruit
genotypes that could also reflect at fruit level.
