When ‘Sy-2’ (Capsicum chinense) plants are grown under 24℃, the abnormal morphology in their leaves are observed. The trigger for the abnormality seemed to be salicylic acid induction in the plants and the compound induces the active expression of pathogen-related proteins. On the basis of the hypothesis that the growth of ‘Sy-2’ at areas with a constant temperature (24-26℃) will induces pathogen, such as such as viruses, resistance, we cultivated ‘Sy-2’ in Indonesia, tropical country with constanttemperature. On the contrary of the hypothesis, ‘Sy-2’ plants were infected with viruses like control cultivars. However, in some traditional cultivars and ‘Sy-2’ grown in Indonesia, shoots generation from virus infected plants were observed. Longer-time observation should be needed for the evaluation of temperature sensing for pathogen resistance of ‘Sy-2’. In this project, we also collected many cultivars from Indonesia and Caribbean community and found a capsicum cultivar (Capsicum chinense) with the interesting phenotype for temperature response like ‘Sy-2’. The genetic mechanisms for the morphology of the cultivar seemed to be similar to ‘Sy-2’. We should analyze the interesting phenotype in detail and consider how to use the bio-resources in tropical area.

当“ Sy-2”（Capsicum Chinense）植物在24℃下生长时，观察到其叶片中的绝对形态。绝对的扳机似乎是植物中的水杨酸诱导，化合物诱导了与病原体相关蛋白的活性表达。基于假设，即在恒温（24-26℃）区域的“ SY-2”的生长将诱发病原体，例如病毒，耐药性，我们在印度尼西亚培养了“ SY-2”，具有恒定体质的热带国家。在假设的相反，“ SY-2”植物被诸如对照培养体等病毒感染。但是，在印度尼西亚种植的一些传统培养体和“ SY-2”中，观察到了感染病毒的芽产生。评估“ SY-2”病原体抗性的温度敏感性应需要更长的观察。在这个项目中，我们还收集了来自印度尼西亚和加勒比海社区的许多品种，并找到了一个辣椒品种（Capsicum Chinense），具有有趣的表型，用于温度反应，例如“ SY-2”。该品种形态的遗传机制似乎类似于“ SY-2”。我们应该详细分析有趣的表型，并考虑如何在热带地区使用生物资源。
