Phenotypic plas­ti­city in Suaeda maritima

Suaeda mari­tima shows mor­pho­lo­gic­ally dif­fer­ent forms on high and low areas of the same salt marsh. Wetson et al. demon­strate that roots of this halo­phyte have a con­stitutively very high activ­ity of lact­ate dehyd­ro­genase (LDH) regard­less of whether they are grow­ing in aer­ated or severely hyp­oxic con­di­tions, and not the indu­cible increase in activ­ity that has been demon­strated in other plants dur­ing hyp­oxia. This high LDH activ­ity is likely to be a factor in the high phen­o­typic plas­ti­city observed in recip­rocal trans­plants between high– and low-marsh field sites and in sim­u­lated tidal-flow tanks in a glasshouse.

    LDH pro­duces lactic acid in the absence of oxy­gen in anim­als.
    Other than that, what is the sig­ni­fic­ance of this inform­a­tion regard­ing this plant?
    Does it indic­ate some advant­age in growth?
