Summary The circadian timing system involves an autoregulatory transcription/translation feedback loop that incorporates a diverse array of factors to maintain 24‐h periodicity. In Arabidopsis novel F‐box protein, ZEITLUPE (ZTL), plays important role in the control free‐running period clock. As class, proteins are well‐established components Skp/Cullin/F‐box (SCF) class E3 ubiquitin ligases link target substrates core ubiquitinating activity ligase complex via direct association with Skp...
A beech bark disease infested American tree ( Fagus grandifolia Ehrh.) and two uninfested trees were selected in a mature natural stand Michigan, USA, mated to form full-sib families for evaluating the inheritance of resistance scale Cryptococcus fagisuga Lind.), insect element disease. Four half-sib from both also evaluated resistance. Using an artificial infestation technique, adult egg count data collected over 2 years analyzed with generalized linear mixed methods account nonnormal...
Abstract Background Beech bark disease is an insect-fungus complex that damages and often kills American beech trees has major ecological economic impacts on forests of the northeastern United States southeastern Canadian forests. The begins when exotic scale insects feed trees, followed by infection damaged tissues one Neonectria species fungi. Proteomic analysis was conducted proteins from diseased healthy in areas heavily infested with disease. All had signs such as cankers or fruiting...
We used differential display to identify chitosan responsive cDNAs in slash pine cell cultures. Two clones that showed increased mRNA abundance had sequence similarity genes with roles major plant defense responses, clone 18 cinnamic acid 4-hydroxylase, and 30 chitinase.
To increase grafting success rate, a hot callus system was designed and implemented as part of multiagency collaborative project to manage beech bark disease (BBD) through the establishment regional BBD-resistant grafted seed orchards. Five years data from over 2000 graft attempts were analyzed using logistic regression model determine which factors important in success. Variables having largest influence included scion genotype, technical problems, health issues (such chlorosis or...
Introduction Larvae of the invasive emerald ash borer [EAB, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae)], kill over 99% green ( Fraxinus pennsylvanica Marshall) trees they infest, yet a small percentage (“lingering ash”) survive years heavy EAB attack. In face an ongoing invasion that threatens multiple North American species with extinction, any evidence for reproducible defensive responses in native merits investigation. Methods We evaluated capacity three families F 1 progeny...
Abstract Cross-species amplification of six microsatellite markers from European beech (Fagus sylvatica Linn) and nine Japanese crenata Blume) was tested in American grandifolia Ehrh.). Three microsatellites each species were successfully adapted for use found to be highly polymorphic, with 4-22 alleles at locus an expected heterozygosity value 0.291 0.913. Twenty-five trees (including two clonal clusters) a mature stand sampled genotyped compute population statistics. No linkage...
Abstract Native ash tree species in Europe and North America are being devastated by dieback the emerald borer, respectively. As worldwide differ their level of susceptibility to these threats, hybrid breeding may allow resistance be transferred among species. However, we do not know extent which distantly related can crossed, many difficult identify from morphology alone leading some mislabelling living collections. While sequences internal transcribed spacer (ITS) nuclear ribosomal DNA...
Genome-wide discovery of candidate genes for functional traits within a species typically involves the sequencing large samples phenotyped individuals 1 , or linkage analysis through multiple generations 2 . When trait occurs repeatedly among phylogenetically independent lineages genus, more efficient approach may be to identify via detection amino acid residues shared by possessing that 3,4 Here, taking this approach, we loci in genus Fraxinus (ash trees) resistance emerald ash borer beetle...
