Flowers of certain primitive plants produce enough heat to raise their temperatures up to 40 C above the air, and regulate it at a nearly constant level. Like warm-blooded mammals, the flowers increase heat production as environmental temperature falls. However, they thermoregulate on a cellular level, unlike mammals with their complex nervous system. We aim to elucidate the mechanisms involved in regulation of heat-production, with molecular, biochemical and stable isotope techniques. We will investigate spatial and temporal patterns of gene expression and activity of putative regulatory enzymes. The results will have implications for human physiology and agriculture.

某些原始植物的花产生足够的热量，使它们的温度升高到空气以上40摄氏度，并将其调节在一个几乎恒定的水平。 像温血哺乳动物一样，当环境温度福尔斯下降时，花会增加产热。 然而，它们在细胞水平上进行温度调节，不像哺乳动物具有复杂的神经系统。 我们的目的是阐明机制参与调节产热，分子，生物化学和稳定同位素技术。我们将研究基因表达的空间和时间模式以及假定的调节酶的活性。 这些结果将对人类生理学和农业产生影响。
