Última Lipoxygenase activity in Brazilian rice cultivars with variable resistance to leaf blast disease Bragantia Sandhu,Sardul Singh; Mazzafera,Paulo; Azini,Luiz Ernesto; Bastos,Cândido Ricardo; Colombo,Carlos Augusto. Eight rice lines viz. CNA 8983, IAC-1732, IAC-1733, IAC-1748, IAC-1736, IAC-201, Volano and Arborea were evaluated in greenhouse for resistance against the leaf blast disease caused by Magnoparthe gracea. Lines CNA 8983, IAC 1732, IAC 1733 and IAC 1748 showed satisfactory resistance against the blast fungus while IAC 1736 and IAC 201 were intermediate and Volano and Arborea susceptible. All lines did not have lipoxygenase activity increased by methyljasmonic acid, however enzyme activity showed a positive relationship with resistance.

Pilocarpine is an imidazol alkaloid exclusively found in Pilocarpus genus and P. microphyllus accumulates its highest content in the leaves. There is no report in the literature on the variability of the pilocarpine content in this genus. A population of 20 genotypes of P. microphyllus from the state of Maranhão, Brazil, was analyzed for Random Amplification of Polymorphic DNA (RAPD) markers and pilocarpine content. Although it was not possible to establish any correlation between these features, the absence or presence of some markers could indicate in some genotypes a possible association with the content of the alkaloid.
