Influence of a brassinosteroid analogue on soybean (Glycine max (L) Merrill) seedling nodulation
Main Article Content
Abstract
including the beginning, evolution and efficiency of nitrogen
fixation in leguminous root nodules through a self-regulating
mechanism. However, the substances involved in regulating
nodulation have not been fully identified, due to multiple
interactions between phytohormones and other signaling
compounds (nitric oxide, reactive-oxygen species, jasmonic
acid, salicylic acid, uridin, flavonoids and nodulating factors
synthesized by rhizobia). Brassinosteroid analogues have a
similar mode of action to natural brassinosteroids in plants.
The effect of a brassinosteroid analogue (Biobras-16) on
soybean (Glycine max L.) seedling in vitro nodulation was
evaluated in this investigation. Biobras-16 enhanced the
response to Bradyrhizobium-soybean symbiotic interaction
when soybean seeds were imbibed, thus obtaining similar or
higher values than the control in every nodulation variable
analyzed at the concentrations tested (0.01, 0.05 and 0.10 mg.L-1).
Nevertheless, when the analogue was added to plant culture
media, the number of nodules was reduced compared to control
plants. Results prove the use of a brassinoesteroid analogue
to improve the response of Bradyrhizobium-soybean symbiotic
interaction by previously imbibing soybean seeds.
