RNA-seq has become a state-of-the-art technique for transcriptomic studies. Advances in both RNA-seq techniques and the corresponding analysis tools and pipelines have unprecedently shaped our understanding in almost every aspects of plant sciences. Notably, the integration of huge amount of RNA-seq with other omic data sets in the model plants and major crop species have facilitated plant regulomics, while the RNA-seq analysis has still been primarily used for differential expression analysis in many less-studied plant species. To unleash the analytical power of RNA-seq in plant species, especially less-studied species and biomass crops, we summarize recent achievements of RNA-seq analysis in the major plant species and representative tools in the four types of application: (1) transcriptome assembly, (2) construction of expression atlas, (3) network analysis, and (4) structural alteration. We emphasize the importance of expression atlas, coexpression networks and predictions of gene regulatory relationships in moving plant transcriptomes toward regulomics, an omic view of genome-wide transcription regulation. We highlight what can be achieved in plant research with RNA-seq by introducing a list of representative RNA-seq analysis tools and resources that are developed for certain minor species or suitable for the analysis without species limitation. In summary, we provide an updated digest on RNA-seq tools, resources and the diverse applications for plant research, and our perspective on the power and challenges of short-read RNA-seq analysis from a regulomic point view. A full utilization of these fruitful RNA-seq resources will promote plant omic research to a higher level, especially in those less studied species.

The efficient use of energy is an important strategic issue concerning our energy security and double carbon goals. Many industrial waste gases, such as oil refineries, contain a lot of ethylene, which is a gas that is harmful to people and the environment. The use of high-efficiency burners to reduce ethylene emissions is a proven and convenient way, so the improvement and optimization of high-efficiency burners has become a hot research issue nowadays. In this paper, a new porous media burner is designed, and a numerical model of the structure is established based on finite element software. The porous media burner is used to treat low calorific value ethylene and effectively reduce the direct emission of low calorific value ethylene in wastewater treatment and chemical industries. Based on the model, the combustion characteristics and pollutant emission characteristics of premixed gas at different equivalence ratios and different flow rates were investigated. The results show that the maximum combustion temperature can reach 1757K with a constant inlet flow rate of premixed gas and a full combustion at an equivalent ratio of 0.85; the maximum temperature increases rapidly with the increase of flow rate at an inlet flow rate of 0.65-0.85 m/s with a constant equivalent ratio, and the temperature rise effect increases slowly when the flow rate is higher than 0.85 m/s; the new porous media The maximum reduction of pollutant emissions of the new porous media burner reaches 37.9%. This study has a guiding effect on the design and engineering application of porous media combustion devices.
