A team of scientists in Singapore has made a breakthrough in identifying the molecular mechanism used by the black rot bacteria, Xanthomonas, to attack and weaken plant immune systems. This discovery, which remains non-genetically engineered, paves the way for the development of bacteria-resistant crops and more precise plant diagnostic methods. The research is particularly relevant to Singapore, where urban farming is on the rise and the warm, wet climate poses ideal conditions for the black rot bacteria to spread. The findings also highlight the need for ongoing research and surveillance to safeguard food security in Singapore and other regions threatened by black rot.

By Shabana Begum Every year between 2004 and 2013, swathes of cabbage grown in fields and greenhouses across New York were attacked by a lethal bacteria that severely wilted the leaves, sometimes making the vegetables appear scorched. During winter in Turkey between 2004 and 2006, patches of cabbage, broccoli and Brussels sprout were found rotten and withered. For over a century, little was known about this untreatable plant epidemic called black rot, which threatens food security worldwide. Black rot disease on a cabbage.PHOTO: SUSAN B. SCHEUFELE But a group of scientists in Singapore have, for the first time, identified how this "crop killer" bacteria hijacks plants at the molecular level and cripple their immune system. Their findings will pave the way for plant biologists to better treat infected plants and find ways to rear bacteria-resistant crops without using genetic engineering, said the study's lead, Associate Professor Miao Yansong from Nanyang Technological ...
