PlastidTransformationforAbioticStressToleranceinPlants
Abiotic stresses such as drought, salinity, and extreme temperatures are major limiting factors in plant growth and development and pose serious threat to global agricultural production. Here we describe a procedure, using a tobacco plastid transformation vector, to generate transplastomic plants with an enhanced ability to tolerate abiotic stresses such as salinity, drought, or cold str......阅读全文

基因转型(gene－transformation)
目的带有特定基因的质体在分子生物研究上，是一个很重要的工具，将质体送入细菌的过程称为基因转形，经由基因转型可使质体在细菌中大量复制，以备进一步研究。本实验将把你在前面转殖实验中cDNA和质体DNA的连结反应送入细菌。 你将从本实验学习如何进行基因转型作用。原理早在1970年左右，有人发现细菌经由冰冷
