Injuries caused by citrus leafminer (Phyllocnistis citrella) exacerbate citrus canker (Xanthomonas axonopodis pv. citri) infection Trop. Plant Pathol.
Jesus Junior,Waldir C.; Belasque Júnior,José; Amorim,Lilian; Christiano,Rock Seille C.; Parra,José Roberto P.; Bergamin Filho,Armando.
After the introduction of citrus leafminer in São Paulo State, an increase in the number of new plants infected with citrus canker has been observed. The interaction between these two organisms is known, but there is no information about how the leafminer damage intensifies citrus canker incidence and severity. The objectives of this paper were to evaluate the effects of leafminer damage in citrus canker infection and its influence on the monocyclic components of the disease on Citrus limonia. Higher incidence of diseased plants, AUDPC (area under the disease progress curve), disease severity and shorter incubation periods were observed in plants inoculated after insect infestation. These factors explain the association found between the higher citrus...

Multiple introductions and gene flow in subtropical South American populations of the fireweed, Senecio madagascariensis(Asteraceae) Genet. Mol. Biol.
Mäder,Geraldo; Castro,Luana; Bonatto,Sandro Luis; Freitas,Loreta Brandão de.
Abstract Non-indigenous plants exhibit different attributes that make them aggressive competitors with indigenous plants and serious threats to biodiversity.Senecio madagascariensis (fireweed, Asteraceae), a native from southern Africa, is a strong competitor in agricultural activities and has toxic alkaloids that may result in high cattle mortality. In Brazil, this weed was collected for the first time in 1995 and has since spread quickly throughout the Pampas region. To better understand the invasion of the fireweed in South America, we used a genetic characterization with internal transcribed spacer (ITS) and microsatellite markers. Based on the ITS data, the southern Brazil populations of S. madagascariensis shared genetic homology with samples taken...

The reproduction and identification of ancient dairy products in East Asia were conducted based on "SEIMINYOUJYUTU" which is the order ancient document available in East Asia and contains detailed explanation about milk processing,and then the spread pathway of these milk processing techniques into East Asia was discussed in this paper. As the results of reproduction and identification experiments,RAKU was identified as sour milk,KANRAKU could not be identified,ROKURAKU was identified as unmatured type cheese such as KHOROOT of Mongolian pastoralists and KURUT of Turki pastoralists,and SO was identified as butter and butter oil. Since some imprecise descriptions were found in SEIMINYOUJYUTU through the reproduction experiment,it was considered that...
