Genomic Imprinting and Inheritance

35.8K
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...

Summary
This summary is machine-generated.

Researchers studied gene expression in maize plants capable of asexual reproduction (apomixis). They found key differences in genes related to DNA methylation and chromatin modification in parthenogenic embryos, offering insights into apomixis mechanisms.

Area of Science:

  • Plant Biology
  • Genetics
  • Developmental Biology

Background:

  • Angiosperms exhibit sexual and asexual (apomixis) reproduction.
  • Apomixis involves embryo and endosperm development without fertilization.
  • Maize's apomixis mechanism is impaired, unlike in Tripsacum.

Purpose of the Study:

  • To investigate gene expression in parthenogenic maize proembryos.
  • To analyze gene expression in unpollinated embryo sacs (ESs) of a parthenogenic maize line (AT-4).
  • To identify genes involved in apomixis in maize.

Main Methods:

  • Isolation of parthenogenic proembryos from unpollinated ESs of maize line AT-4.
  • Gene expression analysis using quantitative methods.
  • Comparison of gene expression between parthenogenic proembryos and unpollinated ESs.

Main Results:

  • Significantly higher expression of DNA-methylation genes (dmt103, dmt105) and chromatin-modifying genes (chr106, hdt104, hon101) in parthenogenic proembryos.
  • First-time detection of fertilization-independent endosperm (fie1) gene expression in both parthenogenic proembryos and unpollinated ESs.
  • Elevated expression (up to two-fold) of the Zm_fie2 gene in parthenogenic proembryos compared to unpollinated ESs.

Conclusions:

  • Parthenogenic maize proembryos exhibit distinct gene expression patterns compared to unpollinated embryo sacs.
  • Genes involved in DNA methylation and chromatin modification are upregulated during parthenogenesis.
  • The study provides novel insights into the molecular mechanisms underlying apomixis in maize.
