Description:
During sexual reproduction in flowering plants such as Arabidopsis, a tip-growing pollen tube (PT) is guided to the synergid cells of the female gametophyte, where it bursts and releases the two sperm. Here we show that PT reception and powdery mildew (PM) infection, which involves communication between a tip-growing hypha and a plant epidermal cell, share molecular components. NORTIA (NTA), a member of the MLO family originally discovered in the context of PM resistance, and FERONIA (FER), a receptor-like kinase, both control PT reception in synergids. Homozygous fer mutants also display PM resistance, revealing a new function for FER and suggesting that conserved components, such as FER and distinct MLO proteins, are involved in both PT reception and PM infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kessler, Sharon A -- Shimosato-Asano, Hiroko -- Keinath, Nana F -- Wuest, Samuel E -- Ingram, Gwyneth -- Panstruga, Ralph -- Grossniklaus, Ueli -- New York, N.Y. -- Science. 2010 Nov 12;330(6006):968-71. doi: 10.1126/science.1195211.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Plant Biology and Zurich Basel Plant Science Center, University of Zurich, Zollikerstrasse 107, CH-8008 Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21071669" target="_blank"〉PubMed〈/a〉
