Previous glasshouse work with Nicotiana attenuata revealed the role of jasmonate （JA） signaling in flower development, advertisement and defense. However, whether JA signaling mediates flowers＇ filtering of floral visitors in nature remained unknown. This field study revealed that silencing JA signaling resulted in flowers that produce less nectar and benzyl acetone, two pollinatorattractive traits. Meanwhile, flowers of defenseless plants were highly attacked by a suite of native herbivores, and damage to buds in native plants correlated negatively with their JA-lle levels.展开更多

Four Chinese cargo vessels, including one from Hong Kong, were the first to be escorted by Chinese warships. The fleet, consisting of two destroyers and one supply ship, will protect Chinese and foreign vessels passing through the area on request and without charge for a three-month period. The fleet will also help ships carrying humanitarian relief for international organizations. Here cargo ships sail off the coast of Somalia under the escort of destroyer Wuhan (first left) of the Chinese Navy.展开更多
