Pollination and Flower Structure02:40

Pollination and Flower Structure

62.6K
Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

Frequency-dependent Selection01:21

Frequency-dependent Selection

20.1K
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.

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Incomplete Dominance01:43

Incomplete Dominance

19.0K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Area of Science:

  • Plant reproductive biology
  • Evolutionary ecology
  • Sexual conflict in hermaphrodites

Background:

  • Hermaphroditism presents potential for intra- and intersexual conflict between male and female reproductive functions.
  • The impact of these sexual conflicts on pollination efficiency in hermaphroditic species remains under-investigated.

Purpose of the Study:

  • To investigate whether male interference affects pollination efficiency in the self-compatible, moth-pollinated orchid Satyrium longicauda.
  • To quantify the consequences of male function on pollination success and fecundity.

Main Methods:

  • Partial emasculation of S. longicauda inflorescences to reduce male gamete availability.
  • Comparison of pollination success and fecundity between partially emasculated and intact control plants.
  • Color-labeling of pollen to track dispersal by hawkmoth pollinators.

Main Results:

  • Partially emasculated flowers exported more pollen and received more cross-pollen but less self-pollen compared to intact flowers.
  • Fruit set proportion per plant was similar across treatments.
  • Fruits from partially emasculated plants exhibited a higher proportion of viable seeds.

Conclusions:

  • Empirical evidence supports the occurrence of male interference with pollination efficiency in hermaphroditic plants.
  • Male interference can negatively impact plant fecundity, likely due to competition for pollinator services (hawkmoth proboscis).
  • Male competition for siring success may drive the evolution of sexual systems in hermaphroditic, pollinator-dependent plants.
