Abstract:
Predicting how plants allocate to different anti-herbivore defences in response to elevated carbon dioxide (CO2) concentrations is important for understanding future patterns of crop susceptibility to herbivory. Theories of defence allocation, especially in the context of environmental change, largely overlook the role of silicon (Si), despite it being the major anti-herbivore defence in the Poaceae. We demonstrated that elevated levels of atmospheric CO2 (e[CO2]) promoted plant growth by 33% and caused wheat (Triticum aestivum) to switch from Si (?19%) to phenolic (+44%) defences. Despite the lower levels of Si under e[CO2], resistance to the global pest Helicoverpa armigera persisted; relative growth rates (RGRs) were reduced by at least 33% on Si-supplied plants, irrespective of CO2 levels. RGR was negatively correlated with leaf Si concentrations. Mandible wear was c. 30% higher when feeding on Si-supplemented plants compared to those feeding on plants with no Si supply. We conclude that higher carbon availability under e[CO2] reduces silicification and causes wheat to increase concentrations of phenolics. However, Si supply, at all levels, suppressed the growth of H. armigera under both CO2 regimes, suggesting that shifts in defence allocation under future climate change may not compromise herbivore resistance in wheat. |

ABSTRACT.
Isolates with conidial morphologies corresponding to botryosphaeriaceous species were obtained from adult grapevines (Vitis vinifera) showing symptoms of die-back and esca in vineyards from all grape-growing regions of Uruguay and also from canes of asymptomatic mother plants in a commercial nursery. The morphological description of some of the anamorphs matched with their ITS phylogeny, which allowed for the identification of Botryosphaeria dothidea, Diplodia seriata, and Neofusicoccum luteum. Combined analysis of the ITS region and partial translation elongation factor further confirmed the presence of Lasiodiplodia theobromae and Neofusicoccum australe. Isolates belonging with the Neofusicoccum parvum/ribis complex were identified as N. parvum and N. kwambonambiense based on sequence analysis of the RNA polymerase II subunit (RPB2). Lasiodiplodia theobromae, N. parvum, N. kwambonambiense and N. australe are described for the first time from grapevines in Uruguay, while N. kwambonambiense is reported in a different territory and host from those in which this cryptic species was originally described.
