Abstract Norway spruce (Picea abies) is by far the most important timber species in Europe, but its outstanding role future forests jeopardized high sensitivity to drought. We analyzed drought response of at warmest fringe natural range. Based on a 35-year old provenance experiment we tested for genetic variation among and within seed provenances across consecutively occurring strong events using dendroclimatic time series. Moreover, associations between ≈1,700 variable SNPs traits related...
Accumulation of phenolic needle metabolites in Norway spruce is regulated by many genes with small and additive effects correlated the susceptibility against fungal attack. accumulates high foliar concentrations secondary metabolites, important functions for pathogen defence responses. However, molecular genetic basis underlying quantitative variation compounds their role enhanced resistance to infection bladder rust are unknown. To address these questions, a set 1035 genome-wide single...
Abstract Background Low regeneration ability limits biotechnological breeding approaches. The influence of genotype in the response is high both tomato and other important crops. Despite various studies that have been carried out on genetics, little known about key genes involved this process. aim study was to localize genetic factors affecting tomato. Results We developed two mapping populations (F 2 BC 1 ) derived from a previously selected cultivar (cv. Anl27) with low accession wild...
Abstract Background Norway spruce trees in subalpine forests frequently face infections by the needle rust fungus Chrysomyxa rhododendri , which causes significant growth decline and increased mortality of young trees. Yet, it is unknown whether actively respond to fungal attack activating molecular defence responses and/or respective gene expression. Results Here, we report results from an infection experiment, transcriptomes (via RNA-Seq analysis) phenolic profiles UHPLC-MS) control...
Abstract In this work, we have evaluated the host suitability of 29 pepper genotypes Capsicum annuum and 9 related cultivated species C. chinense (4), frutescens (4) pubescens (1) to Meloidogyne incognita in field conditions. The presence/absence resistance genes germplasm were also assessed using PCR ‐specific markers linked N , Me1‐Mech2 Me3‐Me4 Me7‐Mech1 genes. Intraspecific variability for M. was found. According gall index ( GI ) reproduction RI most resistant genotypes, which may...
Ash dieback (ADB), caused by the invasive alien fungal pathogen Hymenoscyphus fraxineus, is an emerging disease that poses major threats to survival of common ash (Fraxinus excelsior) in Europe. Here, we report on a field trial aiming at identification ADB tolerant genotypes while encompassing genetic diversity Austria. Over 35,000 progenies from more than 600 putative mother trees were assessed for symptoms over period three years. One and one susceptible progeny subset tree range (570...
We studied leaf morphology in vitro plants of species segregated from the Solanum peruvianum L. s.l. complex: S. arcanum Peralta, corneliomulleri J.F.Macbr., huaylasense and s.str. In these species, regeneration ability root explants cultured 2 organogenic media (SIM-1 SIM-2) was also evaluated a total 16 accessions. These can be differentiated by number leaflets, leaflet dentation plants, area (for arcanum). Regarding regeneration, intraspecific interspecific variability observed. The...
Needle rust caused by the fungus Chrysomyxa rhododendri causes significant growth decline and increased mortality of young Norway spruce trees in subalpine forests. Extremely rare with enhanced resistance represent promising candidates for practice-oriented reproduction approaches. They also enable investigation tree molecular defence mechanisms against this fungal disease. Here, we combined RNA-Seq, RT-qPCR secondary metabolite analyses during a period 38 days following natural infection to...
The increasing demand for climate-adapted seeds and planting material poses a challenge due to the limited availability, particularly tree species such as oaks. National parks, known their large-standing diversity wide range of habitats, can serve valuable sources identifying trees suitable both initiation breeding conservation strategies. This study aimed identify forest genetic resources Thayatal Park in Austria by selecting potentially drought-tolerant phenotypes. For this purpose, we...
