An in vitro experiment was conduced under bacteriologically controlled conditions to examine the effect of light on the production of pectin methyl esterase (PME) and pectin polygalacturonase (PG) in the root exudates of Trifolium alexandrinum inoculated with an efficient strain of Rhizobium trifolii. The results revealed that PME and PG increased with an increase in the duration of light to which plants were exposed. However, both the enzymes were detected in the root exudates of nonphotosynthesizing plants.
在细菌学控制条件下进行了一项体外实验,以研究光照对接种高效三叶草根瘤菌的埃及三叶草根系分泌物中果胶甲酯酶(PME)和果胶多聚半乳糖醛酸酶(PG)产生的影响。结果表明,PME和PG随着植物暴露于光照时间的增加而增加。然而,在非光合植物的根系分泌物中也检测到了这两种酶。
