e0“many of the gene expression alterations appeared to be related to enhanced biosynthesis of jasmonate and ethylene, and consequent enhancement of the genes and pathways that are regulated by these hormones, or to the retrograde signalling caused by the reduced photosynthetic activity and sugar metabolism”

- Intervention effect AC2 expression induced clear leaf and flower phenotypic changes in tobacco.
- Intervention effect AC2-expressing tobacco leaves had 1118 differentially expressed genes.
- Intervention effect AC2-expressing tobacco flowers had 251 differentially expressed genes.
- Observation The most up-regulated tobacco transcript groups related to stress, cell-wall modifications and signalling.
- Observation The most down-regulated tobacco transcript groups related to translation, photosynthesis and transcription.
- Mechanism Many tobacco expression alterations appeared related to enhanced jasmonate and ethylene biosynthesis and their regulated pathways.
- Association Some tobacco genes were induced by both AC2 and HC-Pro, typically at higher expression levels with AC2.
- Observation Many transcript alterations were specific to each RSS-expressing tobacco plant type.
- Mechanism AC2 interfered with tobacco silencing machinery.
- Mechanism AC2 caused stress and defence reactions via jasmonate and ethylene biosynthesis and hormone-regulated expression changes.
- Mechanism Changed sugar metabolism may significantly down-regulate ribosomal-protein genes and reduce general translation in tobacco.
