A Simple and High Quality Method for Isolation and Extraction of Total RNA of Pholiota adipose

Analyzing functional values of RNA using RNA-seq technology is a hot spot of researches. In order to study the medicinal value of Pholiota adipose from the transcriptome level,it is necessary to extract and isolate RNA samples of high purity and high quality P. adipose. In this study,liquid nitrogen grinding Trizol one-step method was used to extract the total RNA of P. adipose. Quality test and statistical comparative analysis were carried out for RNA extract of liquid nitrogen grinding treated and untreated P. adipose. The results showed that the concentration of RNA in the samples treated with liquid nitrogen was much higher than that of the samples without grinding treatment. The OD260/280 of both was about 2,indicating that the purity of RNA was very high. Besides,the ratio of fluorescence intensity of 25 S and 18 S subunit strips of three replicate samples was 1. 8,1. 9,and 1. 9,close to 2,indicating RNA integrity is good. RIN test results of Agilent 2100 were 9. 1,8. 7,and 9. 3,higher than the standard value 6. 8,further proving the integrity. In sum,liquid nitrogen grinding Trizol one-step method is a very simple and efficient method for extracting high quality total RNA of P. adipose.

Effects of Sowing Time on Biological Yield of Forage Sorghum[Sorghum bicolor(L.) Moench] in Autumn Idle Land

[Objective] This study was performed to explore the correlation between sowing time and biological yield of forage sorghum in autumn. [Method] In field trials,forage sorghum was sown on six different dates( July 23,July 29,August 6,August 14,August 22 and August 30). Then,seedling emergence stage,jointing stage,booting stage,heading stage,filling stage,fresh weight and dry weight in each plot were observed or measured. Finally,linear regression analysis on these data was carried out to deduce the correlation between sowing date and biological yield of forage sorghum. [Result]Sowing time showed a significant influence on biological yield of forage sorghum in idle land,and the biological yield of forage sorghum linearly decreased with the postponement of sowing time. The relationship between sowing time and biological yield of forage sorghum can be represented by the regression equations y_(fresh)= 196. 646-4. 625 x and y_(dry)= 58. 253-1. 423 x,wherein,x is sowing date,y_(fresh)and y_(dry)are the fresh weight and dry weight of forage sorghum. On average,the fresh weight of forage sorghum was reduced by 4. 625 kg/20 m^2,and dry weight by 1. 423 kg/20 m^2,when the sowing date was delayed by one day from July 23 to August 30. [Conclusion]The regression models built in this study will provide a theoretical basis for improving the yield of forage sorghum in autumn idle land.

[ Objectives ] The aim was to optimize the configuration of seedling density and line spacing of forage sweet sorghum （ Sorghum blcolor （ L. ） Moench） and explore its high-yield cultivation techniques. [ Methods] Effects of such two influencing factors as line spacing and seedling density on the leaf-stem ratio, DW/FW ratio and grass yield of forage sweet sorghum were analyzed by using split-plot experiment design experiment method and LSD method of IBM. SPSS. Statis- tics. v22 stati, stics software. [ Results ~ Seedling density and line spacing had no obvious effect on the leaf-stem ratio and DW/FW ratio of forage sweet sorghum but had obvious influences on the grass yield. Moreover, the optimal combination of seedling density and line spacing for high yield of forage sweet sorghum was A2 B4, that is, seedling density was 225 000 plants/hm2, and line spacing was 40 cm. [ Conclusions] The results provided a theoretical basis and technical support for high-yield cultivation techniques of forage sweet sorghum.
