Verbatim
e0“NAD kinase activity was measured after short‐term NaCl stress applied to isolated cells from Lycopersicon esculentum , var. Volgogradskij (NaCl‐sensitive tomato) and L. pimpinellifolium , acc. PE2 (NaCl‐tolerant species)”
e1“NAD kinase activity remained constant in the sensitive species, whereas a sharp decrease was observed in the tolerant one”

Other claims from this paper (8)
- Intervention effect In the tolerant L. pimpinellifolium, NAD kinase activity sharply decreased after short-term NaCl stress, whereas it remained constant in the sensitive species.
- Observation After salt treatment, calmodulin gene(s) were induced in both tomato species.
- Intervention effect After salt treatment, active CaM content decreased by 30-50% in L. pimpinellifolium.
- Intervention effect Other ionic stresses and high temperatures decreased NAD kinase activity in L. pimpinellifolium.
- Intervention effect Drought and low temperature exposure did not decrease NAD kinase activity in L. pimpinellifolium.
- Mechanism External Ca2+ appears to play a role in the mechanism leading to NAD kinase inhibition.
- Observation No role could be shown for intracellular Ca2+ in NAD kinase inhibition.
- Mechanism A modification of the redox state of NAD kinase after salt stress seems responsible for the enzyme inhibition.
