Discovery of circadian clock genes important for sorghum resistance to phloem sap-sucking aphids.

Insect herbivory accounts for 15 to 20 percent of annual crop losses globally. Circadianclock impacts the transcriptome plant during their development and in response to abiotic and biotic stresses. To elucidate the impact of circadian clock in the activation of plant defense mechanisms in response to insect infestation, we propose to characterize the transcriptome of sorghum leaves infested with sugarcane aphids (SCA), a phloem sap-sucking insect.

全球范围内，昆虫植食行为每年造成的作物损失占总损失的15%至20%。昼夜节律钟（circadian clock）会在植物生长发育以及应对非生物和生物胁迫时影响其转录组（transcriptome）。为阐明昼夜节律钟在植物应对昆虫侵害时激活防御机制过程中的作用，本研究拟对被甘蔗蚜（Sugarcane Aphids, SCA）——一种刺吸韧皮部汁液的昆虫——侵染的高粱叶片转录组进行特征分析。
