Pharmacological elevation of cyclic AMP (cAMP) of cultured cumulus-oocyte complexes (COC) before or coincident with initiation of maturation has been reported to improve outcomes for various systems for in vitro production of embryos. Here it was hypothesized that artificial elevation of cAMP in the oocyte for a 2-h period of prematuration would improve developmental competence of matured oocytes and result in increased blastocyst yield and altered expression of genes important for embryonic differentiation. Treated COC were cultured for 2 h with dibutyryl cAMP (dbcAMP), a membrane-permeable form of cAMP, and 3-isobutyl-1-methylxanthine (IBMX), which inhibits phosphodiesterases that convert cAMP to ATP.

Spermatogenesis in Lepidoptera holds significant importance due to its unique process of dichotomous spermatogenesis, yielding eupyrene and apyrene spermatozoa through a complex molecular mechanism. While E3 ubiquitin ligases are known to play vital roles in spermatogenesis across various processes, their functions in dichotomous spermatogenesis remain less known. We utilized the RNAi, biochemical and microscopic procedures to unravel the function of in dichotomous spermatogenesis of adult .

Tartary buckwheat (Fagopyrum tataricum), a functional grain known for its medicinal and nutritional properties, has garnered significant attention due to its high flavonoid content and unique health benefits. Heat stress during the flowering stage can lead to sterility in Tartary buckwheat, resulting in reduced yields. This study investigates the effects of a treatment (30/27 °C for 7 days) on flower development, fertility, stress physiology, and gene expression in Tartary buckwheat, while also validating the efficacy of hormone treatments in alleviating the negative effects of heat stress.

Roots play essential roles in the acquisition of water and minerals from soils in higher plants. However, water or nutrient limitation can alter plant root morphology. To clarify the spatial distribution characteristics of essential nutrients in citrus roots and the influence mechanism of micronutrient deficiency on citrus root morphology and architecture, especially the effects on lateral root (LR) growth and development, two commonly used citrus rootstocks, trifoliate orange ( L.

This study explores the effects of a subcritical seawater treatment (SST) on buckwheat waste (BW), and the use of the hydrolysate as a liquid fertilizer to improve the growth of lettuce ( L.). Three temperature treatments (110 °C, 170 °C, 230 °C) were used for the SST, and the ionic composition in the seawater achieved the depolymerization and degradation of BW.
