Enzymatic conversion from pyridoxal to pyridoxine caused by microorganisms within tobacco phyllosphere

Plant Physiology and Biochemistry, 2014
Vitamin B6 (VB6) comprises six interconvertible pyridine compounds (vitamers), among which pyridoxal 5'-phosphate (PLP) is a coenzyme involved in a high diversity of biochemical reactions. In plants, PLP is de novo synthesized, and pyridoxine (PN) is usually maintained as the predominant B6 vitamer.

Dynamic succession patterns and interactions of phyllospheric microorganisms during NOx exposure

Journal of Hazardous Materials, 2022
The phyllosphere plays a role in alleviating air pollution, potentially leveraging the native microorganisms for further enhancement. It remains unclear how phyllospheric microorganisms respond to nitrogen oxide (NOx) pollution and participate in abatement.

The effect of wheat seedling density on photosynthesis may be associated with the phyllosphere microorganisms

Applied Microbiology and Biotechnology, 2020
Wheat seedlings are significantly impacted by the presence of bacteria. However, bacteria are unavoidably growing together with wheat. The study aimed to reveal wheat photosynthesis, phyllosphere bacterial community composition, and a shift in the bacterial community following different density treatments in a closed artificial ecosystem.

Agrichemical impact on growth and survival of non-target apple phyllosphere microorganisms

Canadian Journal of Microbiology, 2007
The impact of conventional agrichemicals commonly used in New Zealand apple production on non-target, culturable phyllosphere microbial populations was studied in the laboratory (agar, leaf, and seedling assays) and field (apple orchard). Morphologically distinct bacteria (three), yeasts (five), and filamentous microfungi (two) were used as indicator ...

Review: Research progress on seasonal succession of phyllosphere microorganisms

Plant Science
Phyllosphere microorganisms have recently attracted the attention of scientists studying plant microbiomes. The origin, diversity, functions, and interactions of phyllosphere microorganisms have been extensively explored. Many experiments have demonstrated seasonal cycles of phyllosphere microbes.

Utility of some nitrogen-fixing microorganisms in the phyllosphere of crop plants

Plant and Soil, 1981
The utility of spraying some known N2-fixing microorganisms on rice leaves grown both in N-less sand culture and under field conditions was examined. The effect was compared with that of spraying a phyllosphere N2-fixing isolate of Klebsiella, KUPBR2, and application of nitrogenous fertilizers. All the growth parameters studied including dry weight and

Epiphytic microorganisms degrading aromatic hydrocarbons from the phyllosphere of urban woody plants

Microbiology, 2017
From the leaves of three urban trees (Tilia sp., Acer sp., and Fraxinus sp.), 180 strains degrading phenanthrene, naphthalene, and salicylate were isolated by direct plating and enrichment cultures. The leaves of each tree species were characterized by a specific profile of aromatic hydrocarbon-degrading microflora.

Interaction of microorganisms within leafy green phyllospheres: Where do human noroviruses fit in?

International Journal of Food Microbiology, 2017
Human noroviruses (hNoV) are one of the major causes of foodborne disease outbreaks linked to leafy greens. However, the interactions-including attachment and persistence-of hNoV with leafy greens are not well characterized. In the present review, three mechanisms are hypothesized for the interaction of hNoV with leafy green phyllospheres: 1) specific ...

Studies of seasonal changes in the microbial populations on the phyllosphere of spring wheat as a prelude to the release of a genetically modified microorganism

Agriculture, Ecosystems & Environment, 1994
Abstract Populations of bacteria, yeasts and filamentous fungi colonising leaf 3, the flag leaf and the ears of spring wheat were analysed over two complete growing seasons in both the glasshouse and field in 1990 and the field only in 1991. Bacterial isolates were identified by analysis of their fatty acid methyl-ester (FAME) profiles and a total of

Utility of phyllosphere N₂-fixing microorganisms in the improvement of growth of some vegetables

Journal of Horticultural Science, 1983
SummaryThree N2-fixing strains of Klebsiella, KUPBR2, KUP4 and KUP6D, were sprayed on the foliage of cauliflower, cabbage, tomato, pumpkin, eggplant, potato, onion, radish, spinach and Trichosanthes dioica, three times at fortnightly intervals. Significant increases were observed in the growth, yield and nitrogen content of the plants. Yields, although
