The ACC deaminase knockout, however, attenuated the plant growth promoting effect of strain Msb3.P. dioscoreaeMsb3 ΔacdS(Msb3ΔacdS) can no longer grow on ACC as carbon or nitrogen source (Supplementary Fig.2) and plants inoculated with it no longer produce the same number of lateral roo...
subsequently, the feedback inhibition of IAA synthesis. However, PGPB with both IAA- and ACC-deaminase-producing activity will control the excess ethylene production level and thereby lessen the ethylene feedback inhibition of IAA biosynthesis. This is because a large ...
