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 present invention adopts the technical proposal of adopting ZSM-5 mesoporous molecular sieve raw powder with a silicon-aluminum mol ratio SiO2Al2O3 of 20 to 1000 and a weight percentage of 20 to 100 percent as well as at least one caking agent selected from SiO2, clay and Al2O3 to extrude, tablet or spray into shape; then treating for 1 to 8 hours by 0.1 to 3 mol/l of at least one ammonium liquor from ammonium nitrate, ammonium chloride or ammonium sulphate or 0.1 to 8.5 mol/l of at least one acid liquor from muriatic acid, nitric acid, vitriol or acetic acid under a temperature of 20 to 90 DEG C; then using steam to treat for 2 to 15 hours under the temperature condition of 400 to 700 DEG C; using a liquor of 0.1 to 3mol/l selected from at least one of oxalic acid, citric acid or maleic acid under a temperature condition of 20 to 90 DEG C to dip for 2 to 5 hours to obtain the modified molecular sieve catalyst, thus better solving the problems.

本发明通过采用硅铝比SiO2/Al2O3为20～1000重量百分比计20～100％的ZSM-5介孔分子筛原粉与余量的选自SiO2、粘土或Al2O3中至少一种粘结剂挤条、压片或喷球成型；再经过0.1～3摩尔/升选自硝酸铵、氯化铵或硫酸铵中的至少一种铵溶液或0.1～8.5摩尔/升选自盐酸、硝酸、硫酸或乙酸中的至少一种酸溶液在温度20～90℃下处理1～8小时；然后在温度为400～700℃条件下水蒸汽处理2～15小时；再用0.1～3摩尔/升选自草酸、柠檬酸或马来酸中至少一种在温度为20～90℃条件下浸渍2～5小时得所需改性分子筛催化剂的技术方案较好地解决了该问题，可用于甲醇转化制丙烯的工业生产中。

Its IR spectrogram performed by potassium bromide showed characteristic absorption peaks in the wavelength of 2917, 2849, 1716, 1463, 1382 and 720cm~(-1), respectively.

EZR_(2002)外观为黄色或黄绿色粉末，熔点在74～79℃之间；经溴化钾压片后的红外光谱图显示在2917、2849、1716、1463、1382和720cm~(-1)处有特征性吸收峰；溶于二氯甲烷后的紫外光谱图显示在412nm处有强吸收，在665nm处有次强吸收，还分别在505、535和605nm附近有弱吸收。

Hence, it is an ideal upgrade or replacement type for the SL252sample presser.
