A fascinating aspect of floral diversity is the dramatic difference in flower size observed in nature. The largest flowers in the world, Rafflesia arnoldii, span several feet while flowers of the genus Wolffia are microscopic! In her latest publication titled "My favourite flowering image: ‘giant’ Arabidopsis flowers", Dr. Beth Krizek shares her personal perspective on flowering and discusses the latested discoveries in the area of plant organ size regulation, including the identification of multiple growth-regulatory pathways as well as functional interactions between different growth genes. A great read!
