Abstract

INTRODUCTION

Flavonoids are the major metabolites in . However, our understanding of the role that flavonoids play in staminate catkin development and pollen maturation is still limited.

METHODS AND RESULTS

Here, we performed a metabolome analysis during staminate catkin development and pollen maturation in . These results indicated that mature pollen exhibited significantly high concentrations and diverse profiles of flavonoids. Moreover, using the integrated transcriptomic and metabolomic analyses, we found major metabolites and key genes involved in staminate catkin development and pollen maturation in the flavonoid pathway. Furthermore, WGCNA analysis identified key transcription factors (, , , and ) as potential regulators in the flavonoid pathway.

DISCUSSION

These findings shed light into the metabolic pathways regulating the development of staminate catkins and pollen maturation in .

摘要

引言

黄酮类化合物是……中的主要代谢产物。然而，我们对黄酮类化合物在雄花序发育和花粉成熟过程中所起作用的了解仍然有限。

方法与结果

在此，我们对……的雄花序发育和花粉成熟过程进行了代谢组分析。这些结果表明，成熟花粉中黄酮类化合物的浓度显著较高且种类多样。此外，通过整合转录组和代谢组分析，我们发现了黄酮类途径中参与雄花序发育和花粉成熟的主要代谢产物和关键基因。此外，加权基因共表达网络分析（WGCNA）确定了关键转录因子（……）作为黄酮类途径中的潜在调节因子。

讨论

这些发现揭示了调控……中雄花序发育和花粉成熟的代谢途径。
