Coccomyxa sp. A2 shows substantially higher aluminum tolerance than Chlamydomonas reinhardtii under their respective optimal pH conditions, revealing multilayered defense strategies.
- Why it matters: Aluminum in acid mine drainage and acidic soils limits survival and biomass, yet the specific tolerance mechanisms in acidophilic algae remain unclear for bioremediation and crop-resistance engineering.
- What they did: The study integrated physiological measurements with transcriptomic and proteomic analyses after aluminum exposure, tracking extracellular and cytosolic organic acids, cell-wall remodeling, and antioxidant responses.
- The result: A2 increased extracellular oxalic, citric, and tartaric acids to chelate Al3+ and remodeled its cell wall, raising cell wall dry weight by 66%, while coordinating a biphasic antioxidant response linked to calcium, abscisic acid, and jasmonic acid.
