1. Aspects of energetic substrate metabolism of in vitro and in vivo bovine embryos
Although the metabolism of early bovine embryos has not been fully elucidated, several publications have addressed this important issue to improve culture conditions for cattle reproductive biotechnologies, with the ultimate goal of producing in vitro embryos similar in quality to those developing in vivo. Here, we review general aspects of bovine embryo met

2. Plant regeneration from long-term callus culture of aaa-group dessert banana.
The banana plant is one of the most widely cultivated crops in the world. However, banana breeding has been a slow process, due to the low seed set and low germination rates. Selection of useful somaclonal variations and genetic transformation in cells or calluses are promising techniques to accelerate the breeding process. Therefore, callus culture was carr

3. Estimating the impact of environmental conditions on hatching results using multivariable analysis
Hatching results are directly related to environmental and biological surroundings. This research study aimed at evaluating the influence of incubation environmental conditions on hatchability and one-day-old chickling quality of five production flocks using multivariable analysis tool. The experiment was carried out in a commercial hatchery located in the s

4. Influence of egg pre-storage heating period and storage length on incubation results
This experiment aimed at evaluating the influence of different heating times of settable eggs of Cobb 500® broiler breeders before submitting them to different storage periods on egg weight loss, embryo mortality, and hatchability. A total number of 1,980 eggs were distributed in a completely randomized experimental design with a 3 x 3 factorial arrangement

5. Resposta superovulatÃria e qualidade de embriÃes de vacas holandesas injetadas com B-caroteno e Tocoferol / Superovulatory response and embryo quality of Holstein heifers and cows supplemented with two doses of β-carotene associate with tocopherol
Avaliou-se o efeito da injeÃÃo intramuscular (IM) de β-caroteno e vitamina E na produÃÃo e qualidade de embriÃes coletados vacas (n=86) e novilhas (n=91) que foram sincronizadas (CrestarÂ) e superovuladas com 8 aplicaÃÃes decrescentes de FSH/LHp em intervalos de 12 horas. Os animais foram inseminados 12 e 24 horas apÃs a observaÃÃo do cio e a

6. Cytogenetics and immature embryo culture at Embrapa Trigo breeding program: transfer of disease resistance from related species by artificial resynthesis of hexaploid wheat (Triticum aestivum L. em. Thell)
Worldwide wheat (Triticum aestivum L. em. Thell, 2n = 6X = 42, AABBDD) breeding programs aim to reorganize genotypes to achieve better yields, environmental adaptation and food quality. The necessary interdisciplinarity for breeding purposes requires an accurate choice of the most appropriate cellular and/or molecular strategies available to be integrated wi
