The genetic backgrounds of resistance mechanisms still remain largely elusive and genomics studies strongly depend on the capacity for phenotyping large panels of plants. Few high-throughput methods have been established for assessing plant resistance to insect herbivores, such as aphids or other piercing...
P. floridana plants infected with the avirulent strain seemed immune to subsequent infection with the virulent strain. Single M. persicae, which had fed on plants infected with the avirulent strain and had transmitted it to healthy plants, subsequently acquired and transmitted the virulent strain,...
Expression of the 5ApMIFtranscripts was analysed by real time RT-PCR on 12-day-old aphids from YR2 and LL01 free of any secondary symbionts [14,37]. In both lineages, transcripts ofApMIF1,ApMIF2andApMIF3, respectively clustered in clade A, C and D, were highly detected in whole bod...
infect plants, or be transmitted by aphid vectors11,12,13. A soluble form of the RTP that is not associated with the capsid plays a role in phloem limitation and movement within the plant host13,14. The readthrough domain itself can be subdivided into a globular N-terminal portion (NRTD...

Scientists have shown that light pollution—especially light in the blue spectrum—can alter the behavior of fish after only a few nights, and have knock-on effects for their offspring. The team from China has studied how ... Plants & Animals 11 minutes ago 0 0 Water-free manufacturing ...
Myzus persicae is an efficient vector of Potato leafroll virus (PLRV); however, PLRV transmission efficiency is significantly reduced when aphids are reared on turnip as compared to Physalis floridana. Turnip-reared aphids are also larger and have a fitness advantage. To glean insight into the ...
Under field conditions, sprays of NSO and neem seed extract to plants had no significant impact on the number of aphids parasitized. Although total numbers of predators were reduced, numbers of predators relative to aphid numbers were similar to those in controls. Neem insecticides may be suitable...
floridana. The concentration of PLRV in leaf extracts differed only slightly when potato plants were kept at 15, 20, 25 or 30 掳C for 1 or 2 wk, but the virus content of aphids kept on leaves at the different temperatures decreased with increase of temperature. PLRV was transmitted ...
