... to quantify stigma and ovary morphology. We demonstrate the suitability of the approach, which uses light-microscopy imaging and machine learning, for the analysis of floral organ traits in field-grown plants using fresh and fixed samples. We show that the unpollinated carpel undergoes a well-defined initial...

...Kristina Gremski; Gary Ditta; Martin F. Yanofsky Successful fertilization in plants requires the properly coordinated development of female reproductive tissues, including stigma, style, septum and transmitting tract. We have identified three closely related genes, HECATE1 (HEC1), HECATE2 (HEC2...

...Gregory M. Zinkl; Benjamin I. Zwiebel; David G. Grier; Daphne Preuss To investigate the nature and role of cell adhesion in plants, we analyzed the initial step of pollination in Arabidopsis : the binding of pollen grains to female stigma cells. Here we show this interaction occurs within seconds...
