Project description:In past studies the hypothesis of "self-toxicity of natural regeneration barriers of Spruce tianshan" were proposed, and verified that 3, 4-dihydroxyacetophenone (DHAP) contained in litter of Spruce Tianshan was the direct cause of population regeneration barriers.The molecular basis of DHAP-induced autotoxicity was explored through transcriptomic analysis of young roots of spruce tianshan treated with DHAP (3,4 dihydroxyacetophenone).
