Abstract Background: The plant-growth-promoting rhizobacterium Tsukamurella tyrosinosolvens is a rare strain of
actinomycete, in order to recognize and expand the ecological functions of rare actinomycetes. Methods: In this
experiment, we studied the effect of Tsukamurella tyrosinosolvens P9 on the drought resistance of peanut by
inoculating peanut seedlings in pots and measuring the growth and physiological indicators of peanut under drought
stress and re-watering conditions. Results: The results showed that during drought stress, the relative water content of
the soil and leaves, chlorophyll content, and stomatal length, width, and aperture were significantly decreased while
the levels of malondialdehyde (MDA), H2O2 and stomatal… More >
