Article Abstract
Growth traits are important economic characteristics of livestock and poultry. In the present study, the expression features of and the relationship between gene polymorphisms and growth traits in Hu sheep were investigated by using real-time quantitative PCR technology (qPCR), Sanger sequencing, and Kaspar genotyping technology. The qPCR results showed that the gene is expressed widely in the tested tissues of Hu sheep, and the expression level of the gene in the heart and the muscle was significantly higher than in other tissues ( < 0.05). Missense mutation c.62565119 A > G was found in , and an association analysis showed that it was correlated with the growth traits (body weight, body height, and body length) of Hu sheep ( < 0.05). The body weight, body height, and body length of the sheep carrying the AA genotype were remarkably higher than those of the GG and AG genotypes ( < 0.05). These results showed that novel polymorphisms at the gene can be used as a genetic marker of growth traits of Hu sheep.

La Trobe University, Melbourne, Victoria, Australia.
Background: Grit, resilience and a growth mindset are traits that help health professional students respond positively and adapt to the challenges of the clinical learning environment. The aim of this study was to determine if a 5-week education-based intervention can enhance grit, resilience and a growth mindset in physiotherapy students on clinical placement.
Methods: In this single group intervention study, physiotherapy students participated in a 5-week group-based, online educational intervention for 1 h per week during their first clinical placement.

Maize (Zea mays L.) is one of the world's most widely cultivated and economically important cereal crop, serving as a staple food and feed source in over 170 countries. However, its global productivity is threatened by late wilt disease (LWD), a disease caused by Magnaporthiopsis maydis, that spreads through soil and seeds and can cause severe yield losses.

Excessive use of agrochemicals results in contamination of water due to runoff or leaching. Insecticide induced-hormesis, a phenomenon characterized by low dose stimulation following exposure to insecticide, is crucial to insect pest resurgence. In this study, the effects of low or sublethal concentrations of emamectin benzoate and thiamethoxam on biological traits and genes expression were investigated for yellow fever mosquito, Aedes aegypti following 48 h exposures.

Weeds are one of the major constraints for wheat productivity, causing significant yield losses worldwide. While chemical control is the most used practice to overcome weed damage, its efficacy is challenged by increasing weed resistance to most used herbicides, which is an expanding phenomenon caused by herbicide overuse/misuse. Modern wheat varieties are less able to perceive the presence of weeds than old varieties and are therefore less competitive against them and require chemical control to ensure adequate yields.

Grain size is a crucial determinant of rice yield, yet the molecular mechanisms controlling this trait remain only partially understood. Here, we identified the JMJ720 locus as a key regulator of grain size through map-based cloning. The jmj720 mutant was found to exhibit significantly larger grains when compared to the wild type (WT).
