ABSTRACT Cereal grain develops from fertilised florets. Alterations in floret and development greatly influence yield quality. Despite this, little is known about the underlying genetic control of these processes, especially key temperate cereals such as barley wheat. Using a combination near-isogenic mutant comparisons, gene editing analyses, we reveal that HvAPETALA2 (HvAP2) controls organ id...

We describe a surprising new regulatory relationship between two key genes of the Drosophila sex-determination gene hierarchy, Sex-lethal (Sxl) and transformer (tra). A positive autoregulatory feedback loop for Sxl was known to maintain somatic cell female identity by producing SXL-F protein to continually instruct the target gene transformer (tra) to make its feminizing product, TRA-F. We disc...

Chromatin remodeling during sperm maturation could erase epigenetic landmarks on the paternal genome, creating a challenge for its reestablishment on fertilization. Here, we show that selective retention of a chromosomal protein in mature sperm protects the identity of paternal telomeres in Drosophila. The ms(3)k81 (k81) gene is a duplication of hiphop that encodes a telomeric protein. Although...

The paper presents a comparative analysis of two audiovisual commercials targeted at mothers. While the Huggies commercial employs mother identity established in 20th-century media discourse, Frida Mom challenges this normative by constructing more complex identity. major argument is that stance-taking as discursive practice enables persuader to build intended and thus influence persuadee’s dec...
