Abstract： In plasma turbulence, such as the solar wind, the helical and (nearly) periodic structures are not necessarily linear waves. Plasmas in different environments present different dynamical characters, admitting various nonlinear structures. It is presented here two alternative nonlinear mechanisms that lead to relevant chirality issues in solar wind, the helical turbulent modes and breathers. The former is explained by revisiting a recent proposal in studying solar wind with the extended magnetohydrodynamics, and the latter is argued with a list of sources of information from water waves, plasmas and Bos\'e-Einstein condensates, though a concrete solar wind model for it is still open.
