Multiple genotypes within aecial clusters in Puccinia graminis and Puccinia coronata: improved understanding of the biology of cereal rust fungi

Fungal Biology and Biotechnology, 2017
Background Cereal rust fungi (Puccinia spp.) are among the most economically important plant pathogens. These fungi have a complex life cycle, including five spore stages and two hosts.

Evaluation of the Physiological Host Range for the Parasitoid Ooencyrtus mirus, a Potential Biocontrol Agent of Bagrada hilaris

Insects, 2020
The thelytokous egg parasitoid Ooencyrtus mirus Triapitsyn and Power (Hymenoptera: Encyrtidae) was recovered from brassica plant debris in Pakistan in an effort to find a biological control agent of the invasive bug Bagrada hilaris (Burmeister ...

Aphid gene expression following polerovirus acquisition is host species dependent

Frontiers in Plant Science
Upon acquisition of persistent circulative viruses such as poleroviruses, the virus particles transcytose through membrane barriers of aphids at the midgut and salivary glands via hemolymph.

Alternative host shapes transmission and life‐history trait correlations in a multi‐host plant pathogen

Evolutionary Applications, 2022
Abstract Most pathogens are generalists capable of infecting multiple host species or strains. Trade‐offs in performance among different hosts are expected to limit the evolution of generalism. Despite the commonness of generalism, the variation in infectivity, transmission, and trade‐offs in performance among ...

Life in a rock pool: Radiation and population genetics of myxozoan parasites in hosts inhabiting restricted spaces.

PLoS ONE, 2018
IntroductionIntertidal rock pools where fish and invertebrates are in constant close contact due to limited space and water level fluctuations represent ideal conditions to promote life cycles in parasites using these two alternate hosts and to study ...

Multiband Slot-Based Dual Composite Right/Left-Handed Transmission Line

Advanced Electromagnetics, 2012
A dual Composite Right-/Left-Handed Transmission Line (CRLH TL) implementation that presents multiband behaviour is proposed in this contribution. The artificial TL is realized by loading a host microstrip line with alternate rectangular stubs and slots.

ALTERNATIVE HOSTS OF Alternaria cucumerina

, 2009
A mancha ou queima de alternaria em cucurbitáceas é causada pelo fungo Alternaria cucumerina. Esta doença é uma das mais severas em solos arenosos e causa danos devido ao desfolhamento que predispõe os frutos à queimadura do sol, além de redução no tamanho e qualidade dos mesmos.

Host-Range Evolution: Adaptation and Trade-Offs in Fitness of Mites on Alternative Hosts [PDF]

Ecology, 2000
Trade-offs in fitness on different host plants has been a central hypothesis in explaining the evolutionary specialization of herbivores. Surprisingly, only a few studies have documented such trade-offs. In this paper, I present results from a selection experiment that demonstrates trade-offs in host plant use for a polyphagous spider mite.
