AAP bacteria are known as an aquatic bacterial group and numerous studies suggest that they play an important role in carbon cycling in the ocean. Recently, AAP bacteria have also been discovered in terrestrial environments, such as soils, plant phyllosphere and endosphere. However, there is little information about terrestrial AAP bacteria, including their prevalence, and interactions with plant hosts. Recently, Shared Light project (University of Jyv\u00e4skyl\u00e4) has collected plant-associated AAP bacteria from four different countries to examine the prevalence of the bacteria from boreal to arctic climate. Their results showed that AAP bacteria were present in nearly every plant species collected, with Methylobacterium sp. and Sphingomonas sp. being the most common bacterial genera.\n\nIn this study, four plant species were collected from two cities in Japan to investigate whether AAP bacteria also occur in warm East-Asian environments and to identify which AAP bacterial species are found in Japan. The isolated AAP bacteria were identified to the genus level and the results were compared with the previous data. Out of the total 24 leaf and 12 branch samples collected, 13% of AAP bacteria were found in the phyllosphere, 4% in the endosphere and 42% in branches. All collected plant species contained AAP bacteria, with a higher prevalence observed in the branches of Pinus sp. compared to other plant species. 9 different species of AAP bacteria were found in the collected samples, all belonging to the genus Methylobacterium sp. There was a clear difference between the AAP bacteria species isolated in Japan and from boreal\u2013arctic climates, as Sphingomonas sp. was not found in samples from Japan. The sample size and the number of species collected in Japan were small, which might have affected the result. Further research is needed to determine the factors, such as host plant species, climate, temperature or humidity, that influence the differences in AAP bacterial species and their prevalence.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2024-08-12T07:10:21Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-08-12T07:10:21Z (GMT).
