TACALITI, M.S; TOCHO, E  and  CASTRO, A.M. Differential esterase activity in aerial and root tissues from 6as DHR wheat lines after phytohormonal treatments. BAG, J. basic appl. genet. [online]. 2016, vol.27, n.1, pp.41-42. ISSN 1852-6233.

Activity of aerial and root esterases in wheat DHR lines of chromosome 6AS was tested. Different patterns were found after applying phytohormone treatments that mimic stress conditions. Ethylene treated plants showed the lowest aerial and root weights; also, the smallest foliar area, in conjunction with absence of esterase activity in more than half of the lines, was observed. Additional studies will contribute to clarify the key role of ET in the expression of defense related genes.
