Implication

Controlled experimental study reveals variable fig cultivar susceptibility and temperature-dependent Thyrostroma parviniae spread across diverse woody hosts, highlighting risks under climate warming.

Key Points

To evaluate the susceptibility of various fig cultivars to Thyrostroma parviniae and determine its temperature-dependent pathogenicity across alternative fruit and ornamental tree hosts.
Inoculated young saplings of multiple fig cultivars under greenhouse conditions using wounded-stem and cut-stem assays with the aggressive isolate S83-47 (CBS 154727).
Assessed detached shoot infections across diverse woody plant species at controlled temperatures of 15°C, 20°C, and 25°C.
Fig cultivars 'Gilasi', 'Payves', and 'Sabz' demonstrated high susceptibility with rapid vascular colonization, whereas the fresh-fruit cultivar 'Matti' showed markedly reduced lesion development.
Detached shoots of almond, apricot, elm, pomegranate, red mulberry, and walnut sustained infection, developing the most severe lesions at 25°C compared to 15°C and 20°C, whereas apple and quince remained asymptomatic.
Multivariate analyses confirmed disease severity in fig, pomegranate, and walnut escalates significantly at elevated temperatures, signaling heightened risk under climate warming.
