The Role of Endogenous Phenolics in Host Plant Resistance Among Malus Taxa to Japanese Beetles
نویسندگان
چکیده
Nature of Work: Japanese beetles (JB), Popillia japonica Newman, are destructive, highly polyphagus herbivores that show a general preference for plants in the Rosaceae family. Although Malus taxa are often found to be susceptible to JB, there are substantial differences in resistance among Malus species and cultivars (1,2). In a prior study, total phenolic levels in Malus were not correlated with JB resistance (2). The objectives of this study were to compare natural resistance to JB among Malus taxa and to evaluate the role of individual phenolics in host plant resistance.

Dispersal patterns of endogenous bacteria among grass carp (Ctenopharyngodon idellus) guts
The formation and regulation of vertebrate endogenous intestinal microbiota has been widely studied as the microbiota plays a crucial role in the host nutrition, development, and health. Despite the importance of microbiota for host health, it is still unclear whether the endogenous intestinal microorganisms are genetically distinct or whether they are genetically related with each other in dif...

The genus Septoria includes important plant pathogens with worldwide distribution, commonly associated with leaf spots and stem cankers of a broad range of plant hosts. In this study, eight isolates of Septoria were recovered from leaves with leaf spot on four herbaceous and woody plants from Gilan, Ardebil, East and West Azerbaijan provinces in north and northwest of Iran. The isolates were st...

متن کاملSusceptibility of fruit from diverse apple and crabapple germplasm to attack by plum curculio (Coleoptera: Curculionidae).
Plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), is an important apple, Malus domestica Borkh., pest that significantly hinders sustainable apple production in eastern North America. The potential for host plant resistance to plum curculio among apple germplasm has never been rigorously evaluated. Thus, studies were conducted to assess the susceptibility of a number o...
