question: What kind of tree is the plant that Streptomyces avicenniae is isolated from?
answer: mangrove tree
context: Title: Avicennia marina
  Passage: Avicennia marina, commonly known as grey mangrove or white mangrove, is a species of mangrove tree classified in the plant family Acanthaceae (formerly in the Verbenaceae or Avicenniaceae).  As with other mangroves, it occurs in the intertidal zones of estuarine areas.
  Title: Streptomyces avicenniae
  Passage: Streptomyces avicenniae is a bacterium species from the genus of "Streptomyces" which has been isolated from the rhizosphere of the plant Avicennia marina in the Fujian Province in China.
  Title: Streptomyces griseoviridis
  Passage: Streptomyces griseoviridis is a filamentous bacterium species from the genus of "Streptomyces" which has been isolated from soil in Texas in the United States.  "Streptomyces griseoviridis" produces etamycin, griseoviridin, bactobolin, prodigiosin R1 and rosophilin.  "Streptomyces griseoviridis" inhibits the growth of fungal pathogens and can be used to protect plants from those.
  Title: Streptomyces olivaceus
  Passage: Streptomyces olivaceus is a bacterium species from the genus of "Streptomyces" which has been isolated from soil.  "Streptomyces olivaceus" produces granaticin, elloramycin, tetroazolemycin A and tetroazolemycin B.  "Streptomyces olivaceus" can be used to produce vitamin B12.
  Title: Streptomyces lydicus
  Passage: Streptomyces lydicus is a bacterium species from the genus of "Streptomyces" which has been isolated from soil in the United States.  "Streptomyces lydicus" produces actithiazic acid, natamycin, lydimycin, streptolydigin, and 1-deoxygalactonojirimycin.  "Streptomyces lydicus" can be used as an agent against fungal plant pathogens like Fusarium, Phytium, Phytophthora, Rhizoctonia and Verticillum.
  Title: Streptomyces olivochromogenes
  Passage: Streptomyces olivochromogenes is a bacterium species from the genus of "Streptomyces" which has been isolated from soil. "Streptomyces olivochromogenes" produces ferulic acid.  The xylose isomerase from "Streptomyces olivochromogenes" is used in the food industry.
  Title: Streptomyces murinus
  Passage: Streptomyces murinus is a bacterium species from the genus of "Streptomyces" which has been isolated from soil.  "Streptomyces murinus" produces the actinomycin X complex and glucose isomerase "Streptomyces murinus" can be used for its production of glucose isomerase in the food industry.
  Title: Venturicidin
  Passage: Venturicidins (also known as aabomycins) are a group of antifungal compounds.  The first member of this class was isolated from "Streptomyces" bacteria in 1961.  Additional members of this class were subsequently isolated and characterized.  An antifungal substance "aabomycin A" was isolated from "Streptomyces" in 1969.  However, in 1990 it was reported that aabomycin A is actually a 3:1 mixture of two related components, which were then named aabomycin A1 and aabomycin A2.  The structures of these were shown to be identical with those of the previously characterized compounds venturicidin A and venturicidin B, respectively.  A new analog, venturicidin C, was recently reported from a "Streptomyces" isolated from thermal vents associated with the Ruth Mullins coal fire in Kentucky.
  Title: Streptomyces ipomoeae
  Passage: Streptomyces ipomoeae is a bacterium species from the genus of "Streptomyces" which has beein isolated from rot from potatoes.  "Streptomyces ipomoeae" produces thaxtomin C and ipomycin.  "Streptomyces ipomoeae" can cause soft rot disease on sweet potatoes.
  Title: Streptomyces nitrosporeus
  Passage: Streptomyces nitrosporeus is a bacterium species from the genus of "Streptomyces" which has been isolated from garden soil in Japan.  "Streptomyces nitrosporeus" produces Benzastatin E, Benzastatin F, Benzastatin G Nitrosporeusine A and Nitrosporeusine B and the antibiotics nitrosporin and virantomycin and the inhibitor of angiotensin-converting enzyme foroxymithine.  "Streptomyces nitrosporeus" can degrade cellulose.
