The recent outbreaks of <i>Tomato yellow leaf curl virus</i> (TYLCV) relate to the spread of its primary vector, the whitefly <i>Bemisia tabaci</i>. Here, we investigated the question of whether the better performance of <i>B. tabaci</i> Q, relative to that of the B biotype, on TYLCV-infected tomato plants could be explained by differences in the ability of the <i>B. tabaci</i> Q and B to obtain free amino acids from the virus-infected plants. We found that the TYLCV infection of tomato plants significantly affected the mole percentage (mol%) of free amino acids in the phloem sap of the tomato plants and the mol% of free amino acids in <i>B. tabaci</i> adults and <i>B. tabaci</i> Frontiers in physiologyAmino Acid Utilization May Explain Why <i>Bemisia tabaci</i> Q and B Differ in Their Performance on Plants Infected by the <i>Tomato yellow leaf curl virus</i>.PMC6504830314201039192018JJ358231701818CAAS-ASTIP-IBFCCAAS-ASTIP-IVFGuo LYang ZXie WSu QWang SWu QZhang YCui HYin JfalseAmino Acid Utilization May Explain Why <i>Bemisia tabaci</i> Q and B Differ in Their Performance on Plants Infected by the <i>Tomato yellow leaf curl virus</i>.To make plants more attractive to vectors of viruses, plant-infecting viruses can alter host plant physiology.
