概括
父母暴露于秋军 (FAW) 和大豆 (SL) 的顺序性草食,影响大豆后代的特征. 攻击的顺序极大地影响了跨代植物的反应,影响了生理学和健康,但并没有影响身体防御.
科学领域:
- 植物科学 植物科学
- 生态生态学 生态生态学
- 昆虫学 昆虫学是一门学科.
背景情况:
- 序列性草食对植物生长,生理学,防御和健康有重大影响.
- 连续对植物的食草动物攻击的跨代后果仍然未被充分探索.
研究的目的:
- 研究秋季军虫 (Spodoptera frugiperda,FAW) 和大豆 (Chrysodeixis includens,SL) 对大豆 (Glycine max) 后代的顺序性草食的跨代影响.
- 确定草食动物的身份和攻击序列是否会影响这些跨代结果.
- 评估对后代早期生长,生理性能,身体防御和健康的影响.
主要方法:
- 来自暴露于不同草食序列 (SL-FAW和FAW-SL) 的父母的大豆种子被用于后代实验.
- 对后代进行了发芽,根形态,/蛋白质含量,生理性能,三体密度和健身特征的分析.
主要成果:
- 早期生长特征 (发芽,根形态,/蛋白质含量) 在母体治疗中是相似的.
- 在SL-FAW连续攻击后,在生理和健身特征上观察到显著的跨代影响.
- 在物理防御 (三体密度) 中没有检测到跨代效应.
结论:
- 父母世代中草食动物攻击的序列和身份关键地塑造了大豆中的跨世代植物反应.
- 大豆后代优先投资于生理和健身特征,而不是在跨代压力下的身体防御.
- 这些发现为在多次,连续的生物压力下作物表现提供了新的见解.

Energy Budgets
9.7K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Genomic Imprinting and Inheritance
35.3K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Background and Environment Affect Phenotype
6.7K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Defenses Against Pathogens and Herbivores

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.
