“…For example, we showed that NOG and BTx623 are differentially susceptible to Asian stem borer, Ostrinia furnacalis Guenée. 16 As BTx623 produced more anisole, it might be working as a repellent to stem borers and/or attract their natural enemies. 61 Vice versa , NOG released more linalool, suggesting that linalool might be actually attracting more herbivores to this cultivar.…”

“…For example, sorghum (C4 plant; Sorghum bicolor L.) is the fifth most important cereal, which is, however, quite susceptible to herbivores in the field. 14 , 15 In our previous reports, sorghum suffered up to 6% total leaf damage in the field, 16 while Nipponbare model rice had only about 1% of total leaf damage. 17 Such observations put in question the relative effectiveness of sorghum defense barriers against insect herbivores, which may, in part, be due to limited and/or impaired release of defense-related VOCs from sorghum plants.…”

Acute stress responses include release of defensive volatiles from herbivore-attacked plants. Here we used two closely related monocot species, rice as a representative C3 plant, and sorghum as a representative C4 plant, and compared their basal and stress-induced headspace volatile organic compounds (VOCs). Although both plants emitted similar types of constitutive and induced VOCs, in agreement with the close phylogenetic relationship of the species, several mono- and sesquiterpenes have been significantly less abundant in headspace of sorghum relative to rice. Furthermore, in spite of generally lower VOC levels, some compounds, such as the green leaf volatile ( Z )-3-hexenyl acetate and homoterpene DMNT, remained relatively high in the sorghum headspace, suggesting that a separate mechanism for dispersal of these compounds may have evolved in this plant. Finally, a variable amount of several VOCs among three sorghum cultivars of different geographical origins suggested that release of VOCs could be used as a valuable resource for the increase of sorghum resistance against herbivores.
