Protein phosphorylation is a major post-translational modification, regulating protein function, stability, and subcellular localization. To date, annotated phosphorylation data are available mainly for model organisms and humans, despite the economic importance of crop species and their large kinomes. Our understanding of the phospho-regulation of flowering in relation to the biology and interaction between the pollen and pistil is still significantly lagging, limiting our knowledge on kinase signalling and its potential applications to crop production. To address this gap, we bring together relevant literature that were previously disconnected to present an overview of the roles of phosphoproteomic signalling pathways in modulating molecular and cellular regulation within specific tissues at different morphological stages of flowering. This review is intended to stimulate research, with the potential to increase crop productivity by providing a platform for novel molecular tools.

开花中磷酸化介导的信号传导：作物磷酸化蛋白质组学的前景和回顾

蛋白质磷酸化是一种主要的翻译后修饰，调节蛋白质功能、稳定性和亚细胞定位。迄今为止，尽管作物物种及其大型激酶组具有经济重要性，但注释的磷酸化数据主要适用于模式生物和人类。我们对与生物学和花粉和雌蕊之间相互作用有关的开花磷酸化调控的理解仍然明显滞后，限制了我们对激酶信号传导及其在作物生产中的潜在应用的知识。为了解决这一差距，我们汇集了以前未连接的相关文献，概述了磷酸化蛋白质组学信号通路在不同开花形态阶段特定组织内调节分子和细胞调控中的作用。
