琼脂双扩散血清试验表明，参试的我国花生矮化病毒（ＰＳＶ）６个分离物和株系之间血清学关系十分亲近，而与美国ＰＳＶ－Ｅ和ＰＳＶ－Ｗ株系存在明显的差异。完成对花生致病力不同的ＰＳＶ－Ｍｉ和ＰＳＶ－Ｓ两个株系壳蛋白（ＣＰ）基因的ＲＴ－ＰＣＲ扩增、克隆和序列分析。两个株系ＣＰ基因均含６５４个核苷酸，编码２１８个氨基酸。两株系之间ＣＰ基因核苷酸序列同源性为９９．１％，推导的ＣＰ氨基酸序列同源性为９９．５％。与已报道的ＰＳＶ亚组ＩＰＳＶ－ＥＲ和ＰＳＶ－Ｊ株系ＣＰ基因核苷酸序列同源性为７５．７％～７７．８％，与ＰＳＶ亚组ⅡＰＳＶ－ＷＣＰ基因核苷酸序列同源性为７４．３％－７４．６％。鉴于我国ＦＳＶ株系血清学性质和ＣＰ基因核苷酸序列同源性与ＰＳＶ两个亚组的ＰＳＶ株系存在明显的差异，建议将我国ＰＳＶ株系划为一个新的ＰＳＶ亚组，即ＰＳＶ亚组－Ⅲ。

对β－葡糖苷酸酶（ＧＵＳ）基因在转基因花生Ｔ１－Ｔ３代植株中的活性测定和ＮＰＴＩＩ基因在Ｔ３代植株中的活性和ＰＣＲ检测表明：Ｔ１代的ＧＵＳ基因为１ ∶１、３∶１等分离，Ｔ２和Ｔ３代ＧＵＳ基因符合３：１单基因显性遗传规律的植株数增加，１：１分离单株比例逐渐减少。从Ｔ３代中就可选择到ＧＵＳ基因纯合的单株，得到了４株遗传性稳定的单株，说明ＧＵＳ基因在转基因花生植株后代的遗传应属于单基因显性遗传规律。实验证明，位于同一质粒上的ＧＵＳ和新霉素磷酸转移酶（ＮＰＴＩＩ）基因，在转基因花生植株中表现为连锁遗传。

The carbon dioxide (CO2) conversion to useable compounds remains a great contest to scientists, engineers, and environmentalists with regard to the reverse of the oxidative degradation of organics. This conversion is essential for the development of complementary fuels and raw materials for various industries, which in turn will help in avoiding the drastic increase in tropospheric temperature due to greenhouse effect leading to global warming. The solar energy is the earth's essential power source along with the other various forms of energy for example fossil fuels, hydropower, wind, and biomaterials, etc. The final goal is to establish the artificial photosynthesis, which can be replicated thru various chemical reduction techniques of CO2 by employing appropriate photo-, thermal- and electro-catalysts in order to produce different one carbon atom (C-1) and higher carbon atoms containing products. Besides, the utilization of clean and sustainable CO2 towards high-value products is of great interest today due to the recognized environmental worries and subsequent lessening of the fossil fuels utilization load to meet the energy demand of mankind. This way, solar energy can directly and/or indirectly be altered and stored in chemical energy form for industrial as well as societal applications. In this article our endeavor is to summarize the advances in CO2 chemical reduction research area till date especially in free radical-based methods such as electrochemical, photochemical and plasma chemical for the development of carbon species up to two carbon (C-2) atoms containing products perceived in the chemical reduction of CO2. The author hopes that this piece of work will be helpful to researchers and readers who are focused on the field of CO2.
