AI Article Synopsis
- A study compared pathogen susceptibility and defense gene responses among three kiwifruit cultivars: 'Hortgem Tahi', 'Hayward', and 'Zesy002'.
- 'Hortgem Tahi' showed high susceptibility to sclerotinia but strong resistance to Pseudomonas syringae pv. actinidiae (Psa), while 'Zesy002' was resistant to both diseases, and 'Hayward' was moderately susceptible.
- Treatment with acibenzolar-s-methyl (ASM) increased certain defense gene expressions in all cultivars and induced resistance to Psa in 'Zesy002' and 'Hayward', but negatively impacted sclerotinia resistance in 'Zesy002', whereas methyl jas
Article Abstract
Pathogen susceptibility and defence gene inducibility were compared between the cultivar 'Hortgem Tahi' and the two cultivars of 'Hayward' and 'Zesy002'. Plants were treated with acibenzolar-s-methyl (ASM) or methyl jasmonate (MeJA) one week before inoculation with pv. (Psa biovar3) or , or secondary induction with chitosan+glucan (Ch-Glu) as a potential pathogen proxy. Defence expression was evaluated by measuring the expression of 18 putative defence genes. 'Hortgem Tahi' was highly susceptible to sclerotinia and very resistant to Psa, whereas 'Zesy002' was highly resistant to both, and 'Hayward' was moderately susceptible to both. Gene expression in 'Hayward' and 'Zesy002' was alike but differed significantly from 'Hortgem Tahi' which had higher basal levels of , , , and but lower expression of and . Treatment with ASM caused upregulation of , , , and in all cultivars and induced resistance to Psa in 'Zesy002' and 'Hayward' but decreased resistance to sclerotinia in 'Zesy002'. MeJA application caused upregulation of LOX2 and downregulation of , and but did not affect disease susceptibility. The Ch-Glu inducer induced PR-gene families in each cultivar, highlighting its possible effectiveness as an alternative to actual pathogen inoculation. The significance of variations in fundamental and inducible gene expression among the cultivars is explored.

There is a growing interest in various types of kiwifruits, such as the "yellow" kiwifruit ( var. ) and the "baby" kiwifruit of . These fruits are rich in bioactive compounds, which contribute to their nutraceutical properties, but they nevertheless have a shorter shelf life, resulting in economic losses.

In the last 30 years the incidence of kiwifruit allergy has increased with the three major allergenic proteins being identified as actinidin, kiwellin, and thaumatin-like protein (TLP). We report wide variation in the levels of actinidin and TLP in 15 kiwifruit varieties from the four most widely cultivated Actinidia species. Acidic and basic isoforms of actinidin were identified in Actinidia deliciosa 'Hayward' and Actinidia arguta 'Hortgem Tahi', while only a basic isoform of actinidin was identified in Actinidia chinensis 'Hort16A'.

Biosynthesis of the lilac alcohols and alcohol epoxides from linalool in 'Hortgem Tahi' kiwifruit (Actinidiaarguta) flowers was investigated by incubating flowers with rac-linalool, rac-[4,4,10,10,10-(2)H(5)]linalool, (R)-8-hydroxylinalool and (R)-8-oxolinalool. All substrates were incorporated into the lilac alcohols although the (R)-configured compounds are not normally present in flowers. Biosynthesis of the lilac alcohol epoxides from rac-1,2-epoxy[4,4,10,10,10-(2)H(5)]linalool and rac-[4',4', 8', 8',8'-(2)H(5)]lilac aldehyde epoxide, rather than the lilac alcohols, was examined.
