Main conclusion The 5-leaf-stage rape seedlings were more insensitive to Pi starvation than that of the 3-leaf-stage plants, which may be attributed to the higher expression levels of ethylene signaling and sugar-metabolism genes in more mature seedlings. Abstract Traditional suppression subtractive hybridization (SSH) and RNA-Seq usually screen out thousands of differentially expressed genes. However,...
Main conclusionOsPGIP4overexpression enhances resistance to bacterial leaf streak in rice. Polygalacturonase-inhibiting proteins are thought to play important roles in the innate immunity of rice against fungi. Here, we show that the chromosomal location of OsPGIP4 coincides with the major bacterial leaf streak resistance quantitative...
Small RNAs (sRNAs) are emerging as essential regulators of biological processes. However, several studies have reported that gymnosperms do not express appreciable amounts of 24-nt sRNAs, and conifers in particular may have a unique sRNA-silencing signature. Here, we compared the sRNA transcriptomes of Japanese larch somatic embryos (SE) and seedlings. SE sRNAs exhibited a length bias toward 24 nt,...
MicroRNAs (miRNAs) play essential roles in numerous developmental and metabolic processes in animals and plants. Although the framework of miRNA biogenesis and function is established, the mechanism of miRNA degradation or modification remains to be investigated in plants. Mature miRNAs may be truncated or added nucleotides to generate variants. A detailed analysis of small RNA deep sequencing data...
MicroRNAs (miRNAs) are emerging as essential regulators of biological processes. Somatic embryogenesis is one of the most important techniques for gymnosperm-breeding programs, but there is little understanding of its underlying mechanism. To investigate the roles of miRNAs during somatic embryogenesis in larch, we constructed a small RNA library from somatic embryos. High-throughput sequencing of...
