Abstract

Kartoffeln ergeben pro Flächeneinheit mehr Kalorien als jede andere Nutzpflanze. Sie enthalten wichtige Nährstoffe und bieten der Bevölkerung in ländlichen Anbaugebieten eine Einkommensquelle. Benin ist eines der ärmsten Länder der Welt. Eine Maßnahme, der Armut entgegenzuwirken, wird in der Ausdehnung der Kar­toffelanbaufläche gesehen. Voraussetzung dafür ist, u.a. Klarheit über die Produktionsstruktur in Benin zu erhalten, sowie die Produktionsbedingungen einzuschätzen und in diesem Zusammenhang, Aussagen zur phyto­pathologischen Situation zu treffen. Die Kartoffelanbaugebiete befinden sich in den De­partements Alibori und Atakora im Norden Benins. Die Anbaufläche liegt insgesamt bei ca. 15–20 ha. Eine Ausdehnung auf eine Anbaufläche im vierstelligen Hektar­bereich erscheint denkbar. In diesem Fall ist jedoch eine nationale Pflanzgutproduktion notwendig. Kartoffeln werden, da Bewässerung notwendig ist, traditionell auf einer nahe den Flüssen oder Nebenarmen gelegenen Fläche von 0,25 ha pro Familie angebaut. Das Pflanzgut gelangt größtenteils aus Frankreich oder aus einem der kartoffelproduzierenden Nachbarländer nach Benin. Der Kartoffelertrag liegt bei ca. 15 t/ha. Maßnahmen, den Ertrag zu erhöhen, liegen in der Verbesserung des Bewässerungssystems und der Pflanzengesundheit. Im Ergebnis von Untersuchungen zum Gesundheits­status der in Benin produzierten Kartoffelknollen wurde festgestellt, dass die Kartoffeln einem hohen Befallsdruck durch Ralstonia solanacearum, einem Quarantäneschaderreger im EPPO Raum, ausgesetzt waren und einen moderaten Befall mit Kartoffelviren aufwiesen. In zukünftige Untersuchungen sollten die Nassfäule­erreger R. solanacearum aber auch der Pectobacterium spp. -Komplex verstärkt einbezogen werden., Journal für Kulturpflanzen, Vol. 64 No. 8 (2012)

Abstract

A combination of electron microscopy and genome sequencing is highly efficient in screening for latent virus infections independent of the virus morphology or genome. One example is hoya tobamovirus-2 (HoTV-2 genbank accession number: MT750216.1) that has been reported from symptomatic mixed infected samples in 2011 and also as single, asymptomatic, infection in several Hoya species in Germany. The virus induces no symptoms in experimental host plants including Chenopodium quinoa, N. tabacum 'Xanthi nc', N. benthamiana and N. tabacum 'Samsun nn'. 14 days post inoculation, plant sap homogenates were examined using negative staining. Rod shaped virions of 300nm length were detected in newly developing leaves, confirming systemic infection. The virions' morphology and size indicated presence of a tobamovirus. The virus titer was lower when compared to tobacco mosaic virus (TMV) infected plants. For virus species identification, RNA sequencing data were scanned for virus specific sequences. The assembled virus genome could be assigned to the genus Tobamovirus. Phylogenetic analysis showed it is closely related to Youcai mosaic virus (YoMV). Therefore, polyclonal antisera for YoMV (DSMZ number AS-0527) was used in immuno-electron microscopy. The heterologous antiserum reacted with HoTV-2, while other tobamovirus antisera used in routine tobamovirus detection did not. The binding of antibodies along the virion was irregular when compared to TMV and its homologous antisera. Mixed infected Hoya plants and HoTV-2 infected N. benthamiana leaves were embedded to study the ultrastructure of infected plants displaying latency linking in situ HoTV-2 structures.

Abstract

Petunia hybrida is a popular bedding plant that has a long history as a genetic model system. We report the whole-genome sequencing and assembly of inbred derivatives of its two wild parents, P. axillaris N and P. inflata S6. The assemblies include 91.3% and 90.2% coverage of their diploid genomes (1.4 Gb; 2n = 14) containing 32,928 and 36,697 protein-coding genes, respectively. The genomes reveal that the Petunia lineage has experienced at least two rounds of hexaploidization: the older gamma event, which is shared with most Eudicots, and a more recent Solanaceae event that is shared with tomato and other solanaceous species. Transcription factors involved in the shift from bee to moth pollination reside in particularly dynamic regions of the genome, which may have been key to the remarkable diversity of floral colour patterns and pollination systems. The high-quality genome sequences will enhance the value of Petunia as a model system for research on unique biological phenomena such as small RNAs, symbiosis, self-incompatibility and circadian rhythms.

Abstract

Infection by an endogenous pararetrovirus using forms of both episomal and chromosomal origin has been demonstrated and characterized, together with evidence that petunia vein clearing virus (PVCV) is a constituent of the Petunia hybrida genome. Our findings allow comparative and direct analysis of horizontally and vertically transmitted virus forms and demonstrate their infectivity using biolistic transformation of a provirus-free petunia species. Some integrants within the genome of P.hybrida are arranged in tandem, allowing direct release of virus by transcription. In addition to known inducers of endogenous pararetroviruses, such as genome hybridization, tissue culture and abiotic stresses, we observed activation of PVCV after wounding. Our data also support the hypothesis that the host plant uses DNA methylation to control the endogenous pararetrovirus.
