Project description:MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are short (19â25 nucleotides) non-coding RNA molecules that have large-scale regulatory effects on development and on stress responses in plants.The objective of this study is to investigate the transcriptional profile of miRNAs and other small non-coding RNAs in Verticilliumâinoculated cotton roots. Four small RNA libraries were constructed from mocked and infected roots of two cotton cultured species which are with different Verticillium tolerance (âHai-7124â, Gossypium barbadense L., a Verticillium-tolerant cultivar, and âYi-11â, Gossypium hirsutum L. a Verticillium-sensitive cultivar). The length distribution of obtained small RNA pools was significantly different among libraries. A total of 215 conserved miRNA families were identified in the two cotton species, of them 14 are novel. There were >65 families with different expression between two libraries. We also identified two ta-siRNAs and thousands of endogenous siRNA candidates, and hundred of them exhibited altered expression after inoculation of Verticillium. The profiling of these miRNAs and other small non-coding RNAs lay the foundation for further understanding of small RNAs function in the regulation of Verticillium defence responses in cotton roots.

Project description:Plant roots secrete secondary metabolites to sense the enviroment around them. Among them, terpenes play a prominent role. Terpenes can have either fungistatic or fungicide action. However, their exact role in plant-host interactions is not fully understood. Verticillium longisporum is a soilborne pathogen causing disease in Brasicacae plants. In this project we investigated the transcriptomic changes of this species upon exposure to the β-pinene monoterpene in different time points 0hpi, 8hpi, 24hpi and 24hpi.
