[ Objective ] As an important regulator involved in protein synthesis and gene expression , riboso- mal proteins are crucial for plant growth and development and stress response. In this study , a ribosomal protein family gene OsRPL36A was cloned from rice , and a preliminary study was performed for its bio- logical function , providing a basis for the study of OsRPL36A function. [ Methods ] Bioinformatics tech- niques were used to analysis gene structure , cis -regulatory elements , and evolution process of OsRPL36A . Meanwhile , the expression of OsRPL36A in different tissues and under diurnal rhythm , different hor- mones , and abiotic stresses were analyzed by quantitative real-time PCR ( qRT-PCR ) . [ Results ] ( 1 ) OsR- PL36A encoded 98 amino acids with a 297 bp coding region , which belonged to the ribosomal protein L36 supergene family , and was named as OsRPL36A . ( 2 ) The promoter region of OsRPL36A contained 3 rhythmic expression-related elements , 10 light-responsive elements , 14 hormone-responsive elements , and 27 environmental stress response elements. ( 3 ) The expression of OsRPL36A in leaves was relatively higher than that in other tissues and presented a typical rhythmic expression pattern. The expression of OsRPL36A was in- duced by IAA , high temperature , low temperature , osmotic stress , and so on. [ Conclusion ] OsRPL36A was highly expressed in leaves and presented a typical rhythmic expression pattern. OsRPL36A responded to IAA and might be involved in response to heat shock , low temperature , salt , and osmotic stresses.

By the method of Tenax-TA absorbent adsorption combined with GC-MS, this paper analyzed the changes of the diurnal rhythm of the volatiles in the healthy branches and Batocera horsfieldi-damaged branches of Viburnum awabuki and Betula luminifera, and electroantennogram technique was used to perform a comparative analysis on the electroantennogram (EAG) responses of unmated male and female B. horsfieldi to the volatiles. After the feeding by B. horsfieldi, there was a decrease in the contents of limonene, nonanal, hexadecane, butyl acrylate, and 3-methyl-butanoic acid in damaged branches of V. awabuki and in the neohexane and hexadecane contents in damaged branches of B. luminifera. Simultaneously, new materials such as permethyl 99A, octyl alcohol, iodo, decanal, hexanal, and bioallethrin etc. were newly synthesized in the dama ged branches. The EAG response values of unmated male and female B. horsfieldi adults to the volatiles in the damaged branches of B.luminifera were the highest, being 1.23 mV and 1.38 mV, while to the healthy branches of V. awa buki were the lowest, being 0.95 mV and 1.01 mV, respectively. As for the time period, the EAG response values of the adults to the volatiles were the lowest from 12:00 to 14:00, which accorded with the feeding behaviors of the adults, i.e., taking food in the field in early morning or at dusk.
