For many years, our insight into intercellular signalling in plants was based upon our knowledge of the so-called five classical plant hormones--auxin, cytokinin, ethylene, gibberellin and abscisic acid. However, biochemical and genetic studies have identified peptides that play crucial roles in plant growth and development, including defence mechanisms in response to wounding by pests, the control of cell division and expansion, and pollen self-incompatibility. Genome sequencing has revealed many predicted peptide-encoding genes and possible receptors, and a major challenge of the post-genomics era is to determine the function of these molecules.
多年来，我们对植物细胞间信号传导的认识基于我们对所谓的五种经典植物激素——生长素、细胞分裂素、乙烯、赤霉素和脱落酸的了解。然而，生物化学和遗传学研究已经鉴定出在植物生长发育中起关键作用的肽，包括对害虫伤害的防御机制、细胞分裂和扩展的控制以及花粉自交不亲和性。基因组测序揭示了许多预测的肽编码基因和可能的受体，后基因组时代的一个主要挑战是确定这些分子的功能。
