摘要:Abstract(#br) We have established a technique for isolating, culturing and transforming tobacco zygotes. Zygotes were isolated by microdissection or enzymatic maceration from fertilized embryo sacs. Viable zygotes cocultured with mesophyll protoplasts underwent first divisio...

摘要:Abstract(#br)High-quality Bi 2 Sr 2 CaCu 2 O 8 (BSCCO) films were grown by means of pulsed-laser deposition on 10° off-axis oriented (001) SrTiO 3 substrates. The films exhibit a step-like morphology and they are properly oriented along the (001) direction. Their normal-stat...

摘要:Abstract(#br)We present what is, to the best of our knowledge, the first diode-pumped Nd:La 3 Ga 5 SiO 14 (Nd:LGS) laser emitting at 888 nm, based on the 4 F 3/2 - 4 I 9/2 transition, generally used for a 904 nm emission. The use of a pump module with 16 passes through the crysta...

摘要:Abstract (#br)We constructed two tobacco cDNA libraries from 200 microdissected undifferentiated globular proembryos and 150 just-differentiating heart-shaped embryos using the RT-PCR technique. Through differential screening of the two cDNA libraries, a cDNA clone, designated TH...
