生物英语词汇strategy I plant
这个是啥意思,看一篇文章的题目是
progress inunderstanding the molecular regulation of iton uptake in stategy I plant,前面的我都明白,但最后这个词组是啥意思,

Answer 1

貌似是根据植物对铁元素的吸收机制来区分strategy I 和strategy II的.
好像双子叶和非禾本单子叶植物被划分为strategy I植物.
网上找到了一段话,或许对你有帮助
Iron is abundant in almost all soils, but often in insoluble forms, and plant roots affect iron solubility by one of two strategies. In dicots and the non-grass monocots, iron acquisition is facilitated by a set of mechanisms known as strategy I. These mechanisms include the FRO (ferric reductase oxidase) protein and the IRT (iron regulated transporter) gene. As a strategy I plant, Helianthus annus is expected to be able to take up iron effectively (and in fact to exhibit enhanced capabilities) when internal iron levels are below required amounts, but to reduce the activities of iron acquisition mechanisms when internal iron concentrations are sufficient.

Higher plants are able to develop two different strategies in order to increase iron availability in soils. Strategy I is developed by dicot and non-graminaceous monocot species. Strategy II is developed by graminaceous species.
应该比较清楚了
