Author BiographyPlot SummaryCharactersThemesStyleHistorical ContextCritical OverviewCriticismSourcesFurther ReadingJames Thurber was a prolific writer and artist who published over twenty books of stories, biographies, drawings, sketches, essays, poetry, fables and cartoons. During the 1920s and 1930s, Thurber wrote for the popular and influential literary magazine, The New Yorker. His work for the magazine established his reputation as a comic with a sophisticated sensibility who largely wrote about upper middle-class intellectuals. Much of his work focused on the milieu of East Coast society. Thurber was born in Columbus, Ohio, in 1894, and some of his writing, such as his “mock” memoirs, My Life and Hard Times, treat his experiences as a boy growing up in Ohio. After attending Ohio State University, he worked as a newspaper reporter in Ohio, France, and New York before joining the staff of the The New Yorker in 1927.

IntroductionMaterials and MethodsResultsDiscussionData AvailabilityAuthor ContributionsFundingConflict of Interest StatementAcknowledgmentsSupplementary MaterialNon-coding RNAs (ncRNAs) are a diverse set of RNAs which do not generally code for proteins. They include families of house-keeping ncRNAs and their precursors such as small nuclear ribonucleoprotein particle RNAs (snRNAs), small Cajal body RNAs (scaRNAs), ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), and small nucleolar RNA (snoRNAs) (Shaw and Brown, 2012; Cech and Steitz, 2014). The regulatory ncRNAs include small RNAs such as microRNAs (miRNAs), short-interfering RNAs (siRNAs), and long non-coding RNAs (lncRNAs) which are expressed from intergenic regions or introns and include natural antisense transcripts (NATs). Some lncRNAs are precursors of small RNA production: primary transcripts are processed to miRNAs or siRNAs such as trans-acting siRNAs (tasiRNAs) or natural antisense siRNAs (nat-siRNAs) derived from double-stranded RNA molecules. The regulatory ncRNAs function in a wide range of cellular processes, from the regulation of transcription and splicing, to chromatin modif...Get price

Frontiers | Spectral Composition of Light Affects Sensitivity

IntroductionMaterials and MethodsResultsDiscussionConclusionData Availability StatementAuthor ContributionsFundingConflict of InterestAcknowledgmentsPlants perceive signals from their surrounding environment and regulate their growth and development accordingly (Smith, 1982; Huché-Thélier et al., 2016). Plants are highly sensitive to the spectral distribution of light and perceive changes in the light spectra and intensity through several protein photoreceptors (Fankhauser and Chory, 1997). These photoreceptors are sensitive to specific regions of the spectrum and overlap of action spectra of different plant photoreceptors occur, allowing the plant to detect a wider and more complex range of changes in their light environment (Heijde and Ulm, 2012). Cryptochromes and phototropins are sensitive to blue light (400–500 nm) and ultraviolet (UV) radiation A (UV-A) (315–400 nm), whereas phytochromes perceive red (600–700 nm) and far-red (700–800 nm) light. Moreover, phytochromes and cryptochromes also absorb light in the green wavelength region (500–600 nm) (Folta and Maruhnich, 2007), although the response of these photoreceptors to...Get price
