Defective pollen tube tip-growth induces neo-polyploid infertility
A recent paper published in Science by the Bomblies group (IMPB), shows that newly formed polyploids suffer a severe defect in polar cell growth, which is essential for fertility in plants as it allows sperm to reach ovules, and provides insight into a naturally evolved solution to this challenge.
