WebThese results suggest that the lncR26319‐miR‐2834‐EndoA axis contributes to the endocytic activity in the Vg uptake and leads to the normal progression of oogenesis in the silkworm. Thus, miR‐2834 and EndoA are crucial for female reproduction and could be potential targets for new pest management strategies in lepidopterans. WebUnderstanding: • Spermatogenesis and oogenesis both involve mitosis, cell growth, two divisions of meiosis and differentiation. Gametogenesis is the process by which diploid precursor cells undergo meiotic division to become haploid gametes (sex cells) In males, this process is called spermatogenesis and produce spermatozoa (sperm) In females ...
