概括
生命早期的环境条件,如火灾,塑造了植物生长的形式. 这种早期的发育可塑性会影响植物在整个生命周期中是否变成单茎或多茎.
科学领域:
- 植物生物学 植物生物学
- 生态生态学 生态生态学
- 发育生物学是发展生物学.
背景情况:
- 许多植物物种表现出树木和灌木形式,能够在单茎和多茎生长之间切换.
- 这种生长形式的变化源于多年生长的芽的独特发育路径,受环境因素的影响.
- 早期的生命条件可能会对植物体质和形式产生持久的遗留影响.
研究的目的:
- 研究不同本体遗传阶段的环境因素如何影响植物形状.
- 探索早期生活经验在塑造长期植物发展和生长习惯中的作用.
主要方法:
- 专注于一个通用的物种,Handroanthus ochraceus (Bignoniaceae).
- 研究了各种热带森林和大草原环境中的植物,其火灾干扰和光线可用性各不相同.
- 检查了早期生活环境条件如何影响后续生长形式.
主要成果:
- 在本体发生早期存在的干扰制度决定了个体是否发展为多或单茎植物.
- 发育早期可以诱导生长形式的变化,这表明了显著的生长形式可塑性.
- 早期的环境线索可以建立持续在整个植物生命中的发展轨迹.
结论:
- 植物形式变异可能归因于遗传差异化或表型可塑性.
- 对Handroanthus ochraceus的观察可能可以将其推广到其他木质类型.
- 需要进一步研究木质植物的可塑性及其在本体发生过程中的调制.

28.8K
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.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

01:10Nature and Nurture
20.8K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

02:16Light Acquisition
8.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
