Our previous studies have shown that ubiquitous overexpression of HmgD caused hemocytes proliferation and the formation of melanotic tumors in the Drosophila larvae. To clarify the mechanism of melanotic tumors appearance,we also generated RT-PCR analysis to test the transcriptional changes of PPAE and Spn27A,which encode the key factors in the phenoloxidasecascade pathway from larvae samples of mid-third instar,late-third instar and prior to pupation relative to wild type flies.Our result showed that in the HmgD overexpression mid-third instar larvae,the expression level.of Spn27A was lower than wild type,otherwise the expression level of PPAE was higher than wild type.It suggests that overexpression of HmgD affects the PO cascade pathway.

本研究组前期工作发现，过量表达HmgD引起果蝇幼虫体内血细胞增生，并出现黑色素瘤，为探讨HmgD过量表达导致了血细胞增生即形成黑色素瘤的分子机制，本研究分别提取三龄中期、后期和相对于野生型化蛹前时刻的幼虫的RNA，首先检测了编码酚氧化酶级联反应途径中的两个关键基因PPAE，Spn27A在突变体中的转录发生变化，结果发现，Spn27A在三龄中期的表达量低于野生型，而PPAE的表达高于野生型，表明过量表达HmgD影响了酚氧化酶级联反应途径，低水平的Spn27A不足以抑制PPAE的活性，活化的PPAE催化了PPO的活性，使其转变成有活性的PO，从而促进黑色素的生成，使果蝇体内产生黑色素瘤。

Firstly, the key frames were extracted from the video sequence. Then, the features detected between adjacent key frames were guided and matched by motion displacement, which was calculated by the optical flow field. With the RANSAC robust estimation and cascade of homography matrix, the homography matrix of the adjacent key frame and the nonadjacent key frame was got. Finally, the seamless mosaic was rendered by image blending.
