WORKSHOP -Phenotypic Plasticity in Reponse to Environmental Change: Scaling from the Molecular to Ecosystem Level in Nikko, Japan on October 23 -26, 2007.

这是美国和日本科学家联合举办的国际研讨会的建议，旨在综合植物对光环境的表型可塑性的现有知识，并讨论植物生态生理学作为预测生态系统对全球环境变化行为的关键因素的未来方向。中心焦点将是光合机构在叶片-整株水平上表现出的巨大表型可塑性，这是植物生态生理学的传统尺度，在这方面已经取得了很大进展。从模型研究中我们知道，这种可塑性对冠层光合作用有重要影响。然而，需要更全面地了解这种可塑性的控制，包括物种差异的机制基础及其对林分和生态系统初级生产力的影响。本次研讨会将回顾最近在理解光合可塑性控制及其对环境变化反应的影响方面的进展。它将在考虑潜在机制的分子研究以及在林分生态系统水平上光合生产力和对环境变化的反应的后果方面是独一无二的。美国和日本的生态生理学是从不同的角度发展起来的，这次会议将两国的科学家聚集在一起，旨在促进协同合作。这次会议定于10月23日至26日在日本日光举行，由日本科学促进会提供资金，用于支付会议场地和当地旅行的费用，以及日本科学家的参加费用。这项提案将支付13名美国科学家出席会议的旅费和日常生活费用。在讲习班上提出的论文将发表在一本国际杂志的特刊上。

This is a proposal for a joint international workshop for US and Japanese scientists to synthesize the current knowledge of the phenotypic plasticity of plants in response to light environments, and to discuss the future direction of plant ecophysiology as a key element to predict the ecosystem behaviors to global environmental changes. The central focus will be the great phenotypic plasticity exhibited by the photosynthetic apparatus at the leaf - whole-plant level, the traditional scale for plant ecophysiology, where great progress has been made. It is known from modeling studies that this plasticity can have a significant impact on canopy photosynthesis. However a more holistic understanding on the controls on this plasticity, including the mechanistic basis of species differences, and its implications for stand and ecosystem primary productivity is needed. This workshop will both review recent progress in understanding the controls on photosynthetic plasticity and their implications for responses to changing environments. It will be unique in considering both molecular studies of the underlying mechanisms and also the consequences for photosynthetic productivity and responses to environmental changes at the stand-ecosystem level. Ecophysiology in the US and Japan developed from different perspectives and bringing together scientists from both countries in this meeting is designed to facilitate synergistic collaborations. The conference is scheduled for October 23-26 in Nikko Japan, with funding from the Japan Society for the Promotion of Science to cover the costs of the meeting site and local travel, and the participation of Japanese scientists. This proposal will cover the costs for travel and per-diem for 13 U.S. scientists to enable their attendance. Papers presented at the workshop will be published in a special issue of an international journal.
