Other claims from this paper (14)
- Intervention effect ASM induced resistance to stem inoculation with Psa in glasshouse studies, accompanied by upregulation of SA pathway genes.
- Intervention effect ASM increased PR1 expression by about 5-fold in Hayward relative to untreated controls.
- Intervention effect ASM increased PR1 expression by over 15-fold in Zesy002 relative to untreated controls.
- Intervention effect ASM increased PR2 and PR5 expression by up to 4-fold in both kiwifruit cultivars.
- Intervention effect PR1 and PR5 were more strongly induced by ASM than PR2 in kiwifruit.
- Observation Orchard studies over three seasons confirmed the utility of PR1, PR2 and PR5 for monitoring ASM-induced responses in mature vines.
- Intervention effect Gene expression levels increased 1 d after ASM application in kiwifruit relative to control levels.
- Intervention effect Gene expression levels declined to control levels between 7 and 14 days after ASM application in kiwifruit.
- Intervention effect BAD, Gluc2 and Class IV Chit were responsive to ASM in Hayward and Zesy002.
- Intervention effect EDS1A, NPR3 and NIMIN2 were responsive to ASM in Hayward and Zesy002.
- Intervention effect Phytohormone content did not show a repeatable response pattern to ASM in potted plants or vines.
- Recommendation Defence marker gene expression could guide ASM application schedules in kiwifruit orchards.
- Association In Hayward, gene upregulation was accompanied by a reduction in Psa leaf spotting.
- Association In Zesy002, no relationship between gene upregulation and Psa leaf spotting was measurable.
