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

9602184博耶该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：根作为幼苗建立的一部分而伸长，茎在光照下伸展并排列叶片，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引起了相当大的科学关注。从结构上看，植物是通过产生新细胞和扩大新近产生的细胞来扩大的。在新的细胞生产过程中，当细胞在再次分裂之前大约扩大一倍时，就会发生放大。分裂后，不再分裂的细胞通常会继续扩大，往往会变成原来的10到15倍。因此，植物器官大小的增加主要包括单个细胞的扩大，特别是分裂后的扩大，而器官的形状主要由这种扩大的方向性决定。放大的速度控制着植物生长的速度。尽管它至关重要，但我们对细胞扩大的机制知之甚少。讲习班的目标是探讨如何建立一个概念框架。这次研讨会不是对实地的所有工作进行评估，而是专门讨论今后可能在哪些方面作出富有成效的努力。为了激励工作，主办方会邀请一到两名同事一起撰写研讨会总结。摘要将发表在由美国植物生理学家协会赞助的时事通讯或植物细胞上。人们希望这只是提高人们对植物如何扩大和如何控制植物生长速度的兴趣的第一步。长期目标将是比现在更容易预测速度和大小，这将使植物生长的变化更容易实现。

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.
