与root相关的网络例句 [注：此内容来源于网络，仅供参考]

Root-derived organic carbon is composed of three compartments: root detritus, root eaudates and root symbionts, which represents a large important and potential C sink in forest ecosystems, The known responses of root derived organic carbon and heterotrophic microbes to elevated CO2 were reviewed. Overall, increases in root biomass, productivity, and exudation indicate an augmentation of C inputs into the soil via roots, although changes in root lifespan are still unclear and may modify this flux positively or negatively, Altogether, changes in root chemistry and morphology that may augment soil C storage under elevated CO2 include decreased N concentration and wider root diameter, Alternately, a shift in rooting depth upwards in the soil profile may increase average turnover rates of root detritus. Effects of CO2 concentration on C qualities of root exudates and root symbionts are the least understood components discussed here, Changes of soil heterotropic microbial activity and community under elevated CO2 still remained large uncertainties.

林木根源有机C包括根东通过根枯落物、根系分泌物和根共生菌周转3条途径向土壤输入的有机C，它是森林生态系统中一个重要的、潜在的C汇，综述了根源有机C与其微生物对CO2浓度升高的响应，虽然对根系寿命的变化尚不清楚，但CO2浓度升高将导致根系生物量、生产量、死亡量和分泌物的增加；同时，CO2升高亦促使根共生菌生物量的增加而增加了共生菌的C归还潜力，表明CO2升高使根源有机C的输入增加了，CO2农度升高情况下，根系化学性质和形态特征的这些变化均有利于增加土壤C的吸存；而根分布深度的降低则对土壤C吸存不利；CO2浓度升高对根分泌物和根共生菌质量的影响研究则极少，CO2浓度升高下土壤微生物活性和群落组成的变化存在较大的不确定性，目前CO2浓度升高下林木根源有机C对森林长期C吸存的贡献仍很不清楚。

Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

本研究通过发根农杆菌工程菌LBA1334(含有野生型pRi1855质粒和pIG121HM双元载体质粒，编码NPTⅡ基因和GUS基因)转化烟草沙姆逊，获得了具有卡那霉素抗性烟草发状根，并筛选出良好的单克隆株系，该发状根具有典型的发状根特性(多根毛、多分支、在无激素培养基上快速生长)，通过根尖压片分析，烟草发状根不具备典型的根冠；发状根中烟碱含量1.61％稍高于与天然栽培品种母体根的含量(1.5％左右)，发状根向培养液中释放烟碱，释放量最多时占总烟碱量的81.1％；在无激素的培养基上获得了再生植株。

The root hair morphology of cv. RM109 was observed and compared. The results indicated that in the distance of 1 cm to the apical of seed root, the number of root hair of RM109 was 19% of cv. Oochikara, and the root diameters were not different from cv. Oochikara; in the distance of 8 cm, the number of root hair and the root diameters of RM109 were 45% and 79% of cv. Oochikara, in the distance of 3 cm, the length of the longest root hair was 33% of cv. Oochikara; but the length from the apical of the seed root to root hair initiation was not different.
