ABSTRACT

This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book introduces the concepts of handedness, asymmetry, chirality, spirality, and helicity with particular reference to plants. It analyzes left-right symmetry of plants and animals in a comparative way. The book also emphasizes that studies on asymmetry in animals have been much greater and more in-depth than in plants. It describes the behavioral changes in the vascular cambial cell components, particularly the cambial domains that result due to these behavioral changes that produce spiral-grained wood. The book discusses the role of handedness in fungi. It highlights some aspects of left-right asymmetries in plants and also highlights the fact that these symmetries have received less attention in plants than in animals. The book summarizes the molecular and genetic aspects of handedness in plants. It is also concerned with embryo rotation and circumnutation.
