Pistil final morphology relies on floral meristem homeostasis, proper organ specification and regional differentiation. These are developmental processes in which sophisticated signaling networks are being uncovered. However, further elements for fine-tuning adjustment still remain to be disclosed. At the molecular level, posttranscriptional modulators may fit such a profile. In this work, we d...

Floral organ formation has been the subject of intensive study for over 20 years, particularly in the model dicot species Arabidopsis thaliana. These studies have led to the establishment of a general model for the development of floral organs in higher plants, the so-called ABCDE model, in which floral whorl-specific combinations of class A, B, C, D, or E genes specify floral organ identity. I...

We investigated the physiological and molecular basis of lower fecundity of massugu2 (msg2), which is a dominant mutant of an auxin primary response gene, IAA19, in Arabidopsis thaliana. By measuring the length of all stamens and pistils in inflorescences and the reference growth rate of pistils, we constructed growth curves of pistils and stamens between stages 12 and 15 of flower development....

Cotton is exceptionally sensitive to high temperature during reproductive development, with a negative correlation existing between high temperatures during flowering and yield (Oosterhuis, 2002). Furthermore, reproductive thermosensitivity in cotton is closely associated with the photosynthetic thermosensitivity of the subtending leaf (Snider et al., 2009). For example, high temperature is kno...
