LOTUS CORNICULATUS REGULATES OFFSPRING QUALITY THROUGH SELECTIVE FRUIT ABORTION

1Department of Biology, The Pennsylvania State University, University Park, PA, 16802.
Summary
Lotus corniculatus selectively aborts fruits with fewer seeds. This strategy enhances offspring quality, leading to better germination, seedling vigor, and adult reproductive success in this plant species.
Area of Science:
- Plant reproductive biology
- Ecology
- Evolutionary biology
Background:
- Inflorescences of Lotus corniculatus often abort approximately half of their immature fruits.
- Understanding the patterns and consequences of fruit abortion is crucial for plant reproductive success.
Purpose of the Study:
- To investigate the patterns of fruit abortion in Lotus corniculatus.
- To determine if fruit abortion is selective and its impact on offspring quality.
Main Methods:
- Observational study of fruit abortion patterns in Lotus corniculatus inflorescences.
- Comparison of seed content and offspring performance between naturally aborted and randomly aborted fruits.
Main Results:
- Natural fruit abortion patterns in Lotus corniculatus result in mature fruits with significantly more seeds compared to random abortion.
- Progeny from naturally aborted fruits exhibit higher germination rates, increased seedling vigor, and greater adult reproductive output.
Conclusions:
- Lotus corniculatus exhibits selective fruit abortion, prioritizing fruits with higher seed numbers.
- This selective abortion strategy enhances the average quality and fitness of the plant's offspring.

01:21Frequency-dependent Selection
24.3K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

02:27Background and Environment Affect Phenotype
7.9K
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...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

01:58Fruit Development, Structure, and Function
25.6K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

01:21Nondisjunction
5.3K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...
