Lead (Pb), one of the most toxic heavy metals, can be absorbed and accumulated by plant roots and then enter the food chain resulting in potential health risks for human beings. The radish (Raphanus sativus L.) is an important root vegetable crop with fleshy taproots as the edible parts. Little is known about the mechanism by which radishes respond to Pb(More)
MicroRNAs (miRNAs) are endogenous non-coding small RNAs that play vital regulatory roles in plant growth, development, and environmental stress responses. Cadmium (Cd) is a non-essential heavy metal that is highly toxic to living organisms. To date, a number of conserved and non-conserved miRNAs have been identified to be involved in response to Cd stress(More)
Salt stress is one of the most representative abiotic stresses that severely affect plant growth and development. MicroRNAs (miRNAs) are well known for their significant involvement in plant responses to abiotic stresses. Although miRNAs implicated in salt stress response have been widely reported in numerous plant species, their regulatory roles in the(More)
microRNAs (miRNAs), endogenous non-coding RNAs of approximately 21–24 nucleotides, are important regulators of transcriptional and post-transcriptional gene expression. These regulators play a key role during plant growth and development, including embryogenesis, which is crucial to the life cycle of most plant species. However, although(More)
Increasing evidence has revealed that microRNA (miRNA)-mediated gene regulation plays a significant role in response to heavy metal stresses. However, there is little information available about the expression patterns or roles of miRNAs under lead toxicity stress in plants. The radish is an important root vegetable crop with a fleshy taproot as the edible(More)
microRNAs (miRNAs) are a class of single-stranded endogenous non-coding RNAs that play critical roles in plant growth, development, and environmental stress responses. Temperature is one of the major physical parameters disturbing cellular homeostasis and causing leaf etiolation in plants. Previous studies have reported that several conserved and novel(More)
Radish (Raphanus sativus L.) is an economically important root vegetable crop, and the taproot-thickening process is the most critical period for the final productivity and quality formation. MicroRNAs (miRNAs) are a family of non-coding small RNAs that play an important regulatory function in plant growth and development. However, the characterization of(More)
MicroRNAs (miRNAs) are small noncoding RNAs that play pivotal roles in plant growth, development and stress response. Chromium (Cr) is one of common environmental contaminants possessing potential health hazards to living organisms. To date, little is known about the regulatory roles of miRNAs in response to Cr stress in radish. To systematically identify(More)
Resistance Gene Analogs (RGAs)-based molecular markers can significantly enhance the breeding efficiency for disease resistance in various crops. However, RGAs isolation and RGA-based marker development have not been conducted in radish. In this study, two prevalent approaches, PCR amplification with degenerate primers and data-mining of radish EST(More)
