The structure and transport properties of pit membranes at the interface between the metaxylem and xylem parenchyma cells and the possible role of these pit membranes in solute transfer to the phloem were investigated. Electron microscopy revealed a fibrillar, almost tubular matrix within the pit membrane structure between the xylem vessels and xylem parenchyma of leaf blade bundles in rice (Or...

The leaf growth and cross-sectional area of durum wheat during its development may be reduced under salt stress due to vascular architecture alterations of leaves. A hydroponic experiment was conducted to compare growth rate and vascular architecture changes of two durum wheat cultivars including Shabrang and Yavaroos under 0 and 100 mM NaCl. Plants were sampled at the three-leaf stage growth. ...

Global ecosystems face severe challenges from climate change, environmental pollution, and intensive farming. Among these challenges, frequent intense drought presents a significant threat to plants in both natural managed ecosystems. Roots the rhizosphere, including countless microorganisms, can shape plant responses hence ecosystem health resilience. This ESA symposium focused on how root tra...
