Defense mechanisms in woody tissue are poorly understood, especially in vine colonized by trunk pathogens. However, several investigations suggest that molecular mechanisms in the central tissue of Vitis vinifera L. may be involved in trunk-defense reactions. In this work, the perception of Phaeoacremonium aleophilum and Phaeomoniella chlamydospora alone or together were investigated in cutting...

Species of the genus Coniochaeta (anamorph: Lecythophora) are known as pathogens of woody hosts, but can also cause opportunistic human infections. Several fungi with conidial stages resembling Lecythophora were isolated from necrotic wood samples of Prunus trees in South Africa. In order to reveal their phylogenetic relationships, these fungi were studied on a morphological and molecular (5.8S...

In California's Mediterranean climate, management of grapevine trunk diseases (Botryosphaeria dieback, Eutypa Phomopsis Esca) focuses on protecting vines during the dormant season, when pruning coincides with rain-induced spore dispersal causal fungi (‘trunk pathogens’). Applying protectants (fungicides, toxic barriers, sealants, biocontrol agents) after can minimize infection wounds. For seaso...
