Abstract European ash, Fraxinus excelsior is facing the double threat of ongoing devastation by invasive fungal pathogen, Hymenoscyphus fraxineus and imminent arrival non-native emerald ash borer (EAB), Agrilus planipennis . The spread EAB which currently moving westwards from Russia Ukraine into central Europe, poses an additional substantial to F. While molecular basis for resistance or variation in among genotypes heavily investigated, comparatively little known about traits involved against EAB. In this study we have gathered transcriptomic data inoculated that previously shown different levels susceptibility Resultant datasets show differential gene expression susceptible resistant response infestation. This will provide important information on allow development management plans combat a pending culturally ecologically tree species.

Abstract Trees are constantly exposed to climate fluctuations, which vary with both time and geographic location. Environmental changes that outside of the physiological favorable range usually negatively affect plant performance trigger responses abiotic stress. Long-living trees in particular have evolved a wide spectrum molecular mechanisms coordinate growth development under stressful conditions, thus minimizing fitness costs. The ongoing techniques directed at quantifying stress has significantly increased our knowledge woody plants. However, it is only within recent years advances next-generation sequencing biochemical approaches enabled us begin understand complexity systems underlie these responses. Here, we review progress understanding bases drought temperature stresses trees, focus on functional, transcriptomic, epigenetic, population genomic studies. In addition, highlight topics will contribute plastic adaptive plants context global change.

Since the discovery of ash tree ( Fraxinus spp.) killer emerald borer (EAB; Agrilus planipennis) in United States 2002 and Moscow, Russia 2003, substantial detection management efforts have been applied to contain monitor its spread mitigate impacts. Despite these efforts, pest continues within North America. It has European Ukraine is causing sporadic outbreaks native range China. The dynamics EAB's expansion events appear be linked lack resistant trees invaded ranges, facilitated by abundance or planted American susceptible species. We review recently gained knowledge EAB; ecological, economic, social impacts; past with their successes limitations. also highlight advances biological control, mechanisms resistance, new approaches under development, aim guiding more effective management.

Abstract Background This study focused on the drought tolerance and resilience of two ash species: Fraxinus chiisanensis F. rhynchophylla . These species are distributed in different habitats, suggesting that they have levels tolerance. Understanding their response to stress, particularly during seedling stage, is crucial for selecting developing drought-resistant varieties. aimed compare phenotypic, physiological, transcriptomic characteristics drought-stressed recovered rewatered plants a time-course experiment. Results In , stress resulted more severe growth retardation, temperature increase, faster decline fluorescence response, accompanied by significant rise indices. However, these reactions quickly after rehydration. contrast, exhibited less slower fluorescence, milder increases indices, although many individuals did not fully recover The activity antioxidant enzymes (SOD, CAT, APX) was responsive efficiently while had weaker delayed response.

Despite the ecological and economic importance of European beech (Fagus sylvatica L.) genomic resources this species are still limited. This hampers an understanding molecular basis adaptation to stress. Since will most likely be threatened by consequences climate change, adaptive processes change-related drought stress is major importance. Here, we used RNA-seq provide first stress-related transcriptome beech. In a trial with saplings, 50 samples were taken for RNA extraction at five points in time during soil desiccation experiment. De novo assembly analysis differential gene expression revealed 44,335 contigs, 662 differentially expressed genes between normally watered control group. Gene was specific different points, only significantly group on all sampling days. GO term enrichment showed that mostly involved lipid- homeostasis-related upregulated, whereas oxidative response downregulated stressed seedlings. study gives insights into beech, provides new genetic research species.

Abstract Green ash ( Fraxinus pennsylvanica ) is the most widely distributed tree in North America. Once common, it has experienced high mortality from non‐native invasive emerald borer (EAB; Agrilus planipennis ). A small percentage of native green trees that remain healthy long‐infested areas, termed “lingering ash,” display partial resistance to insect, indicating breeding and propagating populations with higher EAB may be possible. To assist breeding, ecology evolution studies, we report first chromosome‐level assembly genus for F . over 99% bases anchored 23 haploid chromosomes, spanning 757 Mb total, composed 49.43% repetitive DNA, containing 35,470 high‐confidence gene models assigned 22,976 Asterid orthogroups. We also present results range‐wide genetic variation identification candidate genes important traits including potential EAB‐resistance genes, an investigation comparative genome organization among Asterids based on this reference platform. Residual duplicated regions within probably resulting a recent whole duplication event Oleaceae were visualized relation wild olive Olea europaea var. sylvestris used our chromosome construct reference‐guided assemblies 27 previously sequenced taxa, excelsior Thus, significant step forward genomic resources research protection species.
