- 发育生物学是发展生物学.
- 园艺园艺 园艺园艺
背景情况:
- 芽球运动,如葡萄藤中的巫婆 (Vitis vinifera),自发地出现,导致不同的表型和发育缺陷,如矮体和降低生育能力.
- 这些花芽运动虽然对葡萄种植者有害,但对葡萄藤发育过程提供了宝贵的见解.
- 本研究调查了Dakapo和Merlot葡萄品种中的两个独立的巫婆扫病例,以了解它们的发育轨迹和遗传基础.
研究的目的:
- 为了分析巫婆的扫芽的发育特征,在葡萄藤中进行体育运动.
- 为了识别潜在的基因变异,这些运动的基础.
- 为了比较不同葡萄品种的巫婆的不同遗传基础.

02:33Seed Structure and Early Development of the Sporophyte
28.2K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

02:36Meristems and Plant Growth
45.9K
Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

02:19Morphogenesis
28.1K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.
