英文摘要	A cDNA clone of Eucommia ulmoides Oliv. encoding auxin binding protein 1 (ABP1), one of the putative receptors of auxin, was isolated, and the seasonal expression of ABP1 in relation to IAA and ABA annual variation was investigated by different technical approaches including RT-PCR, real-time PCR, northern blotting, western blotting, and immunolocalization. In the cambial region, ABP1 expression at both the protein and the mRNA level was found to be high, low, and remarkably scarce in the active, quiescent, and resting stages, respectively, during cambium periodicity. The signal abundance of ABP1 follows the opposite pattern to ABA accumulation and correlates with auxin responsiveness of the cambial tissues, suggesting a role for ABP1 in mediating auxin-dependent regulation of cambial activation in the activity-dormancy cycle. This paper attempts to explain why IAA would 'boost' the reactivation of a quiescent cambium, and not that of a resting cambium. Results also show that ABP1 expression is improved by IAA, while inhibited by ABA.; Plant Sciences; SCI(E); EI; PubMed; 10; ARTICLE; 14; 3857-3867; 57
