Summary

Plant self-incompatibility (SI) in Brassicaceae is well-studied. This review explores the active S-receptor complex, focusing on accessory molecules like SLG and PCPs, and their role in pollination and unilateral incompatibility (UI).

Area of Science:

  • Plant reproductive biology
  • Molecular genetics
  • Biochemistry

Background:

  • The Brassicaceae family's self-incompatibility (SI) system is the most understood among plants.
  • Recent findings show interactions between S-locus cysteine-rich protein (SCR) and S-locus receptor kinase (SRK) are crucial for SI in Brassica.
  • However, the in vivo molecular mechanisms and the role of accessory molecules in forming the active S-receptor complex remain unclear.

Purpose of the Study:

  • To review the current understanding of the active S-receptor complex in Brassicaceae SI.
  • To highlight potential variations in receptor complex composition and signaling pathways among different S haplotypes.
  • To discuss the involvement of accessory molecules, specifically S-locus glycoprotein (SLG) and pollen coat proteins (PCPs), in pollination and their link to unilateral incompatibility (UI).

Main Methods:

  • Literature review of existing research on plant self-incompatibility in Brassicaceae.
  • Analysis of molecular interactions between S-locus determinants (SCR, SRK).
  • Discussion of accessory molecules (SLG, PCPs) and their functional roles.

Main Results:

  • The minimal components for SI in Brassica involve SCR and SRK interactions.
  • Significant variation exists between S haplotypes regarding receptor complex composition, downstream signaling, and accessory molecule requirements.
  • Accessory molecules like SLG and PCPs likely play critical roles in pollination and are linked to UI.

Conclusions:

  • The precise in vivo structure and function of the S-receptor complex require further elucidation.
  • Understanding S-haplotype variations is key to deciphering the complexities of SI.
  • Accessory molecules are integral to the SI process and its connection to unilateral incompatibility.
