Karrikins are active components of smoke that can promote seed germination and regulate seedling morphogenesis. However, the role karrikins as alleviators abiotic stress remains largely elusive. In this study, we examined whether exogenous application karrikin1 (KAR1) might improve drought tolerance in creeping bentgrass (Agrostis stolonifera cv. PennA4), investigated underlying mechanism. We f...

Vellozia gigantea is a rare, ancient, and endemic neotropical plant present in the Brazilian Rupestrian grasslands. The dichloromethane extract of V. gigantea adventitious roots was phytotoxic against Lactuca sativa, Agrostis stolonifera, and Lemna paucicostata, and showed larvicidal activity against Aedes aegypti. Phytotoxicity bioassay-directed fractionation of the extract revealed one new is...

Creeping bentgrass (Agrostis stolonifera L.) is moderately tolerant to the p-hydroxyphenylpyruvate dioxygenase-inhibiting herbicide topramezone. However, the contribution of plant metabolism of topramezone to this tolerance is unknown. Experiments were conducted to determine if known cytochrome P450 monooxygenase inhibitors 1-aminobenzotriazole (ABT) and malathion alone or in combination with t...
