Many plants show some form of helical growth, such as the circular searching movements of growing stems and other organs (circumnutation), tendril coiling, leaf and bud reversal (resupination), petal arrangement (contortion) and leaf blade twisting. Recent genetic findings have revealed that such helical growth may be associated with helical arrays of cortical microtubules and of overlying cellulose microfibrils. An alternative mechanism of coiling that is based on differential contraction within a bilayer has also recently been identified and underlies at least some of these growth patterns. Here, I provide an overview of the genes and cellular processes that underlie helical patterning. I also discuss the diversity of helical growth patterns in plants, highlighting their potential adaptive significance and comparing them with helical growth patterns in animals. Summary: This Review examines the genetic and cellular basis of helical growth in plants, providing an overview of the various types of helical growth as well as their adaptive significance.

植物器官中的螺旋生长:机制和意义
许多植物表现出某种形式的螺旋生长,例如生长茎和其他器官的圆形搜索运动(circumnutation)、卷须卷曲、叶和芽反转(reupination)、花瓣排列(扭曲)和叶片扭曲。最近的基因发现表明,这种螺旋生长可能与皮质微管和覆盖的纤维素微纤维的螺旋阵列有关。最近还确定了一种基于双层内不同收缩的卷曲的替代机制,并且至少是这些生长模式中的一些的基础。在这里,我概述了作为螺旋图案基础的基因和细胞过程。我还讨论了植物中螺旋生长模式的多样性,强调它们潜在的适应性意义,并将它们与动物的螺旋生长模式进行比较。摘要:本综述研究了植物螺旋生长的遗传和细胞基础,概述了各种螺旋生长类型及其适应性意义。
