Other claims from this paper (11)
- 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.
- Mechanism Expression alterations also appeared related to retrograde signalling caused by reduced photosynthetic activity and sugar metabolism.
- 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 Changed sugar metabolism may significantly down-regulate ribosomal-protein genes and reduce general translation in tobacco.
