Response to vernalization and photoperiod are the main determinants controlling the time to flowering in temperate cereals. While the individual genes that determine a plant's response to these environmental signals are well characterized, the combinatorial effect on flowering time of allelic variants for multiple genes remains unresolved. This study investigated the genetic control of flowering-time in a biparental population of spring barley, derived from a wide cross between a late-flowering European and an early-flowering North-American cultivar. While the major flowering time genes are not segregating in the Beka ×Logan cross, large variation in flowering was observed. We identified five QTL, with both parents found to contribute early alleles. The catalog of QTL discovered aligns with several candidate genes affecting flowering time in barley. The combination of particular alleles at HvCEN, HvELF3 and HvFT1 in Logan are responsible for the earliness of this cultivar. Interestingly, earliness for flowering could be further enhanced, with Beka found to contribute three early alleles, including a QTL colocating with a HvFD-like gene, suggesting that there are diverse aspects of the flowering-time pathway that have been manipulated in these two cultivars. Epistatic interactions between flowering-time QTL or candidate genes were observed in field data and confirmed under controlled conditions. The results of this study link photoperiod-dependent flowering-time genes with earliness per se genes into a single model, thus providing a unique framework that can be used by geneticists and breeders to optimize flowering time in barley.

Transactions of Nonferrous Metals Society of China 2024年

The effects of forward extrusion as well as extrusion combined with reversible torsion (KoBo extrusion)， followed by additional deformation via the MaxStrain module of the Gleeble thermomechanical simulator， on the microstructure， mechanical properties， and electrical conductivity of a Cu-0.7Mg (wt.%) alloy， were investigated in this work. The simulation results highlighted the critical influence of processing history in determining the equivalent strain distribution. The sample subjected to forward extrusion at 400 ℃and subsequent MaxStrain processing (FM sample)， possessed 76% lower grain size compared to the sample processed solely with MaxStrain (AM sample). Likewise， the KoBo-extruded and MaxStrain-processed sample (KM sample) exhibited 66% smaller grain size compared to the AM sample. Tensile test results revealed that the AM， FM， and KM samples， respectively， possessed 251%， 288%， and 360% higher yield strength， and 95%， 121%， and 169% higher tensile strength compared to the initial annealed alloy， as a result of grain refinement as well as deformation strengthening. Finally， the electrical conductivity measurements revealed that AM， FM， and KM samples， respectively， possessed electrical conductivity values of 37.9， 35.6， and 32.0 (MS/m)， which， considering their mechanical properties， makes them eligible to be categorized as high-strength and high-conductivity copper alloys.

SP100 is an antiviral protein that restricts the productive stage of human papillomavirus(HPV)and multiple other viruses,and viruses in turn block sUMO-1-mediated stabilization of SP100 and promotes its degradation(Table S1).Interferon(IFN)signaling could still produce more SP100 through transcription to counteract viruses.1 Viruses also disable the transcriptional up-regulation of SP100 to achieve persistent infection in hosts.
