Abstract

The branches in Polysphondylium pallidum whorls are arranged in a radial pattern. We have used a pattern-specific monoclonal antibody to study branch formation and characterize the origin of this pattern. A quantitative spatial analysis of antibody staining reveals that the branching pattern arises from a random distribution. This distribution passes through a series of intermediate stages to yield a radial prepattern. The origins and evolution of this prepattern are satisfactorily accounted for by models that produce spatial patterns by short-range autocatalytic and longer-range inhibitory forces.

摘要

盘基网柄菌轮生体中的分支呈放射状排列。我们使用了一种针对特定模式的单克隆抗体来研究分支形成并表征这种模式的起源。对抗体染色的定量空间分析表明，分支模式源于随机分布。这种分布经过一系列中间阶段以产生放射状预模式。通过短程自催化和长程抑制力产生空间模式的模型令人满意地解释了这种预模式的起源和演化。
