日本森林综合研究所和物理化学研究所近日决定，今后两三年内在搜集所有白杨树基因的基础上，选取有用基因加以解析，用于培育吸纳、贮存二氧化碳能力强的树木。白杨树大约有５．５万个碱基对，比已经完成基因测序工程的水稻碱基对稍多一点，是最有可能成为率先完成基因测序的 Japan Institute of Forest Synthesis and Institute of Physical Chemistry recently decided on the basis of collecting all poplar genes in the next two to three years and selecting useful genes for analysis to cultivate trees capable of absorbing and storing carbon dioxide. There are about 55,000 base pairs of poplars, slightly more than the base pairs of rice that have already completed the genetic sequencing project, and are most likely to be the first to complete the genetic sequencing
