Pb stressPhased small interfering RNAs (phasiRNAs) are a distinct class of endogenous small interfering RNAs, which regulate plant growth, development, and environmental stress response. To determine the effect of phasiRNAs on maize ( Zea mays L.) tolerance to lead (Pb) stress, the roots of ...
Phased secondary small interfering RNAs (phasiRNAs) are generated by double-stranded RNA (dsRNAs), which are cleaved by Dicer as a phase set. Hundreds of 21-nt and 24-nt phasiRNAs have been identified in male reproductive organs of rice and maize. Whereas, the expression profile of phasiRNAs...
Background Recent results demonstrated that either non-coding or coding genes generate phased secondary small interfering RNAs (phasiRNAs) guided by specific miRNAs. Till now, there is no studies for phasiRNAs in Panax notoginseng (Burk.) F.H. Chen (P. notoginseng), an important traditional Chin...
Small RNAPlantsBioinformaticsShort, interfering RNAs (siRNAs) arise from the processing of long double-stranded RNA (dsRNA) by Dicer enzymes. Dicers generate siRNA duplexes by successive hydrolysis of both strands of the dsRNA phosphodiester backbone at positions determined by measuring 21-24 ...
Phased small interfering RNA (phasiRNA)BioinformaticsMicroRNAs (miRNAs) are a class of endogenous small non-coding RNAs involved in the post-transcriptional gene regulation and play a critical role in plant growth, development and stress responses. Watermelon (Citrullus lanatus L.) is one of the ...
Background Secondary, phased small interfering RNAs (phasiRNAs) derived from protein-coding or noncoding loci (PHAS) are emerging as a new type of regulators of gene expression in plants. However, the evolution and function of these novel siRNAs in plant species remain largely unexplored. Results...
Small RNAs are central players in RNA silencing, yet their cytoplasmic compartmentalization and the effects it may have on their activities have not been studied at the genomic scale. Here we report that Arabidopsis microRNAs (miRNAs) and small interfering RNAs (siRNAs) are distinctly partitioned be...
However, the watermelon miRNAs and phasiRNAs and their functions are not well explored.Results: Here we carried out computational and experimental analysis of miRNAs and phased small interfering RNAs (phasiRNAs) in watermelon by analyzing 14 small RNA profiles from roots, leaves, androecium, ...
In grasses, two types of phased, small interfering RNAs (phasiRNAs) are expressed largely in young, developing anthers. They are 21 or 24 nucleotides (nt) in length, and are triggered by miR2118 or miR2275, respectively. However, most of their functions and activities are not fully ...
Phased small interfering RNAs are produced in rice from a hairpin structure of a long non-coding RNA in a process that is independent of RNA-dependent RNA polymerases.Huang, JiWang, RuqinDai, XinbinFeng, JiejieZhang, HongshengZhao, Patrick X....
