Lipo-chitooligosaccharides (LCOs) are bacteria-to-plant signals required for the establishment of rhizobia–legume nitrogen fixing symbioses. The ability of LCO [Nod Bj V (C18:1, MeFuc)] isolated from B. japonicum (strain 532C), and of oligomers of

Ascophyllum nodosum, a brown macroalga, is the most widely used seaweed in agriculture. We report a rapid method for the detection of cytokinin-like activity in plants treated with a commercial A. nodosum liquid concentrate (Stimplex®) using a trans

Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) and tyrosine ammonia-lyase (TAL, 4.3.1.), the key enzymes of the phenylpropanoid pathway, are inducible in response to biotic (such as chitin from fungal cell walls) and abiotic cues. Application of chiti

On the first day after foliar application, chitosan pentamer (CH5) and chitin pentamer (CHIT5) decreased net photosynthetic rate (PN) of soybean and maize, however, on subsequent days there was an increase in PN in some treatments. CH5 caused an incr

Jasmonates are signaling molecules involved in induced systemic resistance, wounding and stress responses of plants. We have previously demonstrated that jasmonates can induce nod genes of Bradyrhizobium japonicum when measured by beta-galactosidase

Summary Salicylic acid (SA) and related phenolic compounds can excert control over stomatal opening and previous work in our laborabtory has shown that chronic injection of SA increases the photosynthetic rate of corn. The work reported in this paper
