Web10 nov. 2024 · Here we analysed five replicates of six consecutive and accurately staged developmental time points of anthers containing meiocytes spanning the whole of prophase I, a developmental process taking 36–48h. All three 0.6–1.1mm anthers were dissected from individual spikelets from the middle of developing barley inflorescences. Web20 mei 2024 · Cells known as meiocytes make sex cells by dividing through a process known as meiosis. Previous studies have identified several genes that regulate meiosis in plants. For example, a gene known as TAM is required to make sex cells in a small weed known as Arabidopsis thaliana, which is often used as a model plant in research studies.
