China Correspondence should be addressed to Lin Zhongping

A 500-bp cDNA fragment was amplified via RT-PCR from drought-induced total RNA of the drought-tolerant B. crassifolia Hemsl. using primers based on the sequence of published dehydrin conserved region. By using 5’ RACE, full-length coding region (1 148 bp) of BDN1 gene was produced. It is a new member of the dehydrin gene family. Southern analysis indicated that BDN1 is present in the 6. crassifolia genome as a single-copy gene. Northern analysis revealed that its expression is inducible by drought and cold stresses as well as ABA application.

Blocks of Moso bamboo were used as experimental materials to test the toxicity of CuAz preservative on decay fungi by the lab test in this paper. The result showed that the natural decay resistance of 4-year-old Mao bamboo is moderate, and the resistance to brown fungi is stronger than that to white fungi. The anti-fungi properties of CuAz preservative at the retention of 3.3.kg/m3.are equal to those of CCA-C and ACQ-B at the retention of about 4.0 kg/m3., and obviously superior to those of organic acids preservatives.

植物螯合肽 (PCs)广泛存在于植物体中 ,与植物抗重金属胁迫关系密切。植物螯合肽及其复合物是一类富含半胱氨酸的低分子量化合物。现有研究证明 ,PCs由谷胱甘肽 (GSH)为底物的酶促反应合成 ,其合成受相关基因的调控 ,从模式植物拟南芥的突变体中已分离到与 PCs合成有关的几个基因。植物螯合肽首先与重金属离子结合形成低分子量 (LMW)复合物 ,以此形态经由细胞质进入液泡后 ,再与一个分子的植物螯合肽结合 ,形成对植物组织毒性较小的高分子量 (HMW)复合物 ,从而达到缓解重金属对植物的危害作用。就植物螯合肽及其复合物的结构、生物合成、基因调控及重金属解毒机理等进行了综述。
