RNA-seq reads have been deposited in the NCBI Sequence Read Archive under BioProject ID PRJNA421838. The success of using nascent RNA-seq to investigate transcriptional. For qRT-PCR, complementary DNA synthesis and analysis was performed as described before using. However, most of the current ‘RNA. 1: Data S2. Virtually all RNA-seq studies provide a snapshot of the steady state transcriptome, which contains valuable information about RNA populations at a given time but lacks information about the dynamics of RNA synthesis and degradation. . Our previous Arabidopsis RNA-seq database (ARS) has been updated recently, and the number of libraries has been increased from 20 068 to 28 164 (Zhang et al. Moreover, RNA-sequencing technology has been proven to discover numerous genes/factors involved in N gene networks in several crops for multiple traits such as role of N starvation in rice 8,9. (A) The number of Arabidopsis sequenced bases per year from 2009 to 2018. 6 million introns in these four species. A The cartoon demonstrates the workflow of chromatin-bound RNA extraction in Arabidopsis. We evaluated the transcriptome dynamics during the early stages of anther development, identified stage-specific activities of transcription factors regulating this. We also plan to continue updating PPRD regularly by including new libraries and new plant species in the future. , 2012) or Araport 11 (Cheng et al. The first pair of rosette leaves was cut, and the detached leaves. Fig. Practically, the process of scRNA-seq. 5% (STAR). 16, núm. Zhimin Hou, Yanhui Liu et al. Our database includes over 57,000 plant public RNA-seq libraries, comprising 25,283 from Arabidopsis, 17,789 from maize, 10,710 from rice, and 3,974 from soybean, and covers a total of 1. , 2009). High throughput sequencing results of 12 samples, including hypoxia treatments and multiple controls are summarized in Table 1. 0-85095656022.
