Abstract Background Genome-wide change of polyadenylation (polyA) sites (also known as alternative polyadenylation, APA) is emerging an important strategy gene regulation in response to stress plants. But little woody perennials that are persistently dealing with multiple abiotic stresses. Results Here, we performed a genome-wide profiling under heat and cold treatments Populus trichocarpa . Th...

Abstract: We consider the non-parametric maximum likelihood estimation in the class of Polya frequency functions of order two, viz. the densities with a concave logarithm. This is a subclass of unimodal densities and fairly rich in general. The NPMLE is shown to be the solution to a convex programming problem in the Euclidean space and an algorithm is devised similar to the iterative convex min...

For the classical Polya urn model parametrized by exponent γ, the limit distributions of the fraction of balls in each bin are simple and well known when γ < 1 (“egalitarian”) and when γ > 1 (“winner takes all”). In this note, we partially fill in the gap for γ = 1, the critical point, by providing explicit analytical expressions for all the moments of the limit distribution of the fraction of ...

A simple method to assess the degree of degradation present in a total RNA preparation from cells or tissues is based on the increasing probability of RNA cleavage with increasing length of an RNA molecule. Under ideal conditions, reverse transcription of a particular mRNA species with oligo-dT as the primer generates a population of cDNAs, terminating at the 5' end of the mRNA if all template ...

The remarkable stability of microRNAs in biofluids underlies their potential as biomarkers, but their small size presents challenges for detection by RT-qPCR. The heterogeneity of microRNAs, with each one comprising a series of variants or 'isomiRs', adds additional complexity. Presented here are the key considerations for use of RT-qPCR to measure microRNAs and their isomiRs, with a focus on p...
