Bordered pits are cavities in the lignified cell walls of xylem conduits (vessels and tracheids)
that are essential components in the water‐transport system of higher plants. The pit …

Major restrictions to the hydraulic conductance of xylem (K XYL) in vascular plants have
traditionally been attributed to anatomical constraints. More recently, changes in the cationic …

The distribution of intervascular pit membranes with a torus was investigated in juvenile
wood samples of 19 species of Ulmus and seven related genera.• A staining solution of …

A new fossil conifer wood—Brachyoxylon currumilii sp. nov.—is described from the Lower—
Middle Jurassic of Chubut Province (Argentina). The specimens were collected at a locality …

Abstract Background and Aims According to the air-seeding hypothesis, embolism
vulnerability in xylem elements is linked directly to bordered pit structure and functioning. To …

Background and Aims The structure of pit membranes in angiosperms has not been fully
examined and our understanding about the structure is incomplete. Therefore, this study …

Abstract Okra (Abelmoschus esculentus (L.) Moench and Abelmoschus caillei (A. Chev.)
Stevel) belongs to the family Malvaceae. They are grown in many parts of the world …

Endosperm transfer cells in maize have extensive cell wall ingrowths that play a key role in
kernel development. Although the incorporation of lignin would support this process, its …

This study compares intertracheary pit membrane structure and ontogeny in Abies firma
(Pinaceae) and Metasequoia glyptostroboides (Cupressaceae). Initial phases of pit …

Tracheary elements, the water-conducting cells of the xylem, are connected by bordered pit
pairs containing pit membranes. The function of the latter is to allow passage of water but not …
