| Research Abstract |
The molecular mechanisms responsible for selenium(Se) tolerance and hyperaccumulation were studied in the Se hyperaccumulator Stanleya(S.) pinnata by comparing it to the related secondary Se accumulator Stanleya albescens using a combination of physiological, structural, genomic and biochemical approaches. The levels of jasmonic acid and salicylic acid were constitutively elevated in S. pinnata compared to S. albescens, and leaf Se accumulation was slightly enhanced in both species when these hormones were supplied. Thus, defense-related phytohormones may play an important signaling role in the Se hyperaccumulation of S. pinnata.
