Other claims from this paper (10)
- Observation HsfA1 overexpressing plants contained one transgene cassette.
- Mechanism Tandem inverted cassette repeats led to HsfA1 cosuppression and small interfering RNAs.
- Observation Developmental parameters were similar among wild type, overexpressing, and cosuppressed plants in normal growth.
- Observation Cosuppressed tomato plants and fruits were highly temperature sensitive.
- Observation Heat stress induced chaperone and Hsf synthesis was reduced or absent in cosuppressed plants.
- Mechanism HsfA1 had a master regulator role in induced thermotolerance.
- Observation Cosuppression was reproduced in CS protoplasts.
- Intervention effect HsfA2 plasmid restored transcription factor expression and reporter activation in CS protoplasts.
- Observation HsfA1 expression plasmids remained silenced at high amounts.
- Intervention effect Plasmid borne HsfA2 restored thermotolerance, chaperones, luciferase thermoprotection, and heat stress granules in CS protoplasts.
