The nucleus, as the control center of the eukaryotic cell, plays a pivotal role in orchestrating cellular responses to environmental stresses, including salinity. Salt-tolerant plants, such as Artemisia marschalliana, possess unique adaptive mechanisms to thrive in high-salinity environments. This study investigates the distinct structural features of nuclei within the leaf mesophyll cells of Artemisia marschalliana, aiming to elucidate potential ultrastructural adaptations associated with its salt tolerance. Using transmission electron microscopy, we analyzed the chromatin organization, nucleolar morphology, and nuclear envelope integrity. Our findings reveal specific nuclear characteristics, including a well-defined nucleolus with distinct fibrillar and granular components and a relatively dispersed chromatin pattern, suggesting active transcriptional and metabolic processes. These ultrastructural observations provide insights into the cellular strategies employed by Artemisia marschalliana to maintain nuclear homeostasis and cellular function under saline conditions, contributing to a deeper understanding of plant salt tolerance mechanisms.
