从苹果金冠基因组中鉴定得到18 个生长素输出载体蛋白PIN-formed（PIN），对其进行理化
特性、基因结构、系统进化和启动子元件分析。结果表明，MdPIN 基因家族中，含有1 ~ 14 个外显子，
0 ~ 13 个内含子；MdPIN 蛋白的保守基序数量在3 ~ 10。苹果PIN 和拟南芥PIN 等蛋白高度同源，且根
据其进化树分为G1、G2 和G3 亚组；18 个MdPIN 在不同基因...
Relationship between the impedance of a multi-pin probe and soil water content
impedance dielectric constant soil water content multi-pin probe model
2008/11/12
Based on the theory of the impedance-transform of transmission line, a mathematical model for calculating the impedance of a soil probe with a multi-pin structure was developed. It is found that the ...
