Workshop on Plant Growth, in Lewes, Delaware, on August 18-21, 1996.

9602184 Boyer这个奖项为一个研讨会提供支持，以评估我们对植物如何扩大的理解。其结构的扩大是植物最基本的活动之一：根作为幼苗形成的一部分而延长，茎在光线下伸展并排列叶片，生殖结构扩大并允许配子移动和融合。这一过程的核心性质已经引起了相当大的科学关注。从结构的观点来看，人们同意植物通过产生新的细胞和扩大最近产生的细胞来扩大。在新细胞产生的过程中，细胞在再次分裂之前大约会增大一倍。分裂后，不再再分裂的细胞通常会继续扩大，通常会比原来大10到15倍。因此，植物器官大小的增加主要是由单个细胞的增大组成，特别是在分裂后，器官的形状主要由这种增大的方向性决定。扩大的速度控制着植物生长的速度。尽管它具有核心重要性，但我们对细胞扩大的机制知之甚少。研讨会的目标是探讨如何构建一个概念性框架。这次讲习班不是对该领域的所有工作进行评估，而是专门讨论今后可能在哪些方面进行富有成效的努力。为了激励工作，组织者会邀请一到两名同事共同撰写研讨会总结。摘要将发表在由美国植物生理学家协会主办的通讯或植物细胞上。人们希望，这只是提高人们对植物如何生长和如何控制生长速度的兴趣的第一步。长期目标将是比现在更容易地预测速度和大小，这将使植物生长的变化更容易完成。

9602184 Boyer This award provides support for a workshop to evaluate our understanding of how plants enlarge. The enlargement of their structure is one of the most fundamental activities of plants: roots elongate as part of seedling establishment, stems extend and array leaves in the light, reproductive structures enlarge and allow gametes to move and fuse. The central nature of this process has attracted considerable scientific attention. It is agreed from a structural point of view that plants enlarge by producing new cells and enlarging recently produced ones. During new cell production, enlargement occurs as the cells approximately double in size before they divide again. After division, cells that do not re-divide generally continue to enlarge and often become 10 to 15 times as large as they were originally. This, the increase in size of plant organs consists mostly of the enlargement of individual cells particularly after division, and the shape of the organs is determined mostly by the directionality of this enlargement. The rate of enlargement controls how rapidly the plant grows. Despite its central importance, we know little about the mechanisms underlying cell enlargement. The goals for the workshop are to explore how a conceptional framework could be built. Rather than an assessment of all the work in the field, this workshop will be devoted to where productive effort might be placed in the future. In order to stimulate work, the organizer will ask one or two colleagues to join in writing a summary of the workshop. A summary will be published in the Newsletter or The Plant Cell sponsored by the American Society of Plant Physiologists. It is hoped that this would be only a first step toward increasing the interest in how plants enlarge and how the rate is controlled. The long-term goal will be to make predictions of rate and size more easily than is now possible, which will make alternations to plant growth more easily accomplished.
