拟南芥AtFTCD-L参与根系响应土壤紧实度的机制
Mechanism by which AtFTCD-L is Involved in the Root Response to Soil Compaction
摘要
Abstract
INTRODUCTION:Plant roots respond to various abiotic stresses,including drought stress,heavy metal stress,salt stress,and deficiencies in essential nutrients,during their growth and development.Among these factors,soil structure,especially soil compaction,significantly affects root growth and morphology,ultimately influencing crop yield. RATIONALE:The Golgi apparatus plays a role in root growth and responds to abiotic stress through vesicle secretion.However,the mechanisms by which the Golgi apparatus contributes to the response of the root system to soil compaction remain unclear.Previous studies have demonstrated that AtFTCD-L in Arabidopsis is located on the trans-Golgi network(TGN)opposite the Golgi apparatus,and plays a role in vesicle sorting and/or secretion regulation of mucin components in the peripheral cells of the root cap. RESULTS:Compared with those of the wild type,the root tips and root tip cells of the ftcd mutant are shorter in the longitu-dinal direction,but wider in the transverse direction,indicating abnormal cell morphology.Analysis of fluorescent signals from PIN-GFP plants revealed that PIN7 was either not expressed or expressed at very low levels in mutants.This study provides theoretical insights into the adaptive mechanisms of plant roots in response to abiotic stress induced by soil compaction. CONCLUSION:In summary,AtFTCD-L responds to soil compaction in the roots of Arabidopsis by regulating the distri-bution or expression of PIN7.关键词
