Endophytic Pseudomonas fluorescens relieves intraspecific allelopathy of Atractylodes lancea by reducing ethylene transportation.

ABSTRACT:

Background

Endophytes play an important role in promoting plant growth. To date, although many reports provided insight into the function of endophytes in their hosts, few reports focus on their impact on nearby plants. Intraspecific allelopathy in plant community is common and presents a notable challenge to medicinal plant yield and productivity. Atractylodes lancea is a perennial herb that has relatively low yields due to intraspecific allelopathy. The bacterial endophyte Pseudomonas fluorescens ALEB7B has previously been found to increase essential oil content of A. lancea, but the role of ALEB7B in A. lancea allelopathy is still unknown.

Results

Noninoculated A. lancea exhibited growth retardation when it was grown in a community, which was related to ethylene-induced i
