Claim · model-written summary
In shoots of tomato plants with only half of the roots watered, three of the four genes le4, le16 and le20 were induced.
Solanum lycopersicumVerbatim
e1“The expression of four genes, le4, le16, le20, and le25, which require increased ABA content for expression, was studied in tomato plants”
e4“Shoots of plants in which only half of the roots were watered showed no decrease in relative water content and no increase in ABA content; however, three of the four genes, le4, le16, and le20, were induced”

Other claims from this paper (5)
- Association In unwatered tomato plants, le4 and le25 expression correlated with ABA content.
- Association In unwatered tomato plants, le16 and le20 expression occurred before a detectable increase in leaf ABA content.
- Association Shoots of tomato plants with only half of the roots watered showed no decrease in relative water content.
- Association Shoots of tomato plants with only half of the roots watered showed no increase in ABA content.
- Mechanism Genes may also be induced in the tomato shoot by signals from the root.
