Canadian Journal of Botany, 1996 The onion exodermis is made up of two cell types, i.e., long and short cells. Both form Casparian bands, but suberin lamella development is absent or delayed in the short cells. Long cells did not accumulate fluorescein, a common test for cell vitality, because of reduced wall permeability due to suberin lamella development.

Casparian bands and suberin lamellae: Key targets for breeding salt tolerant crops?
Environmental and Experimental Botany, 2021Abstract Soil salinity seriously restricts agricultural production, especially for salt-sensitive crops. Understanding salt-tolerant plants will open new opportunities to crop breeders in attempts to increase salt tolerance in conventional crops. However, until now, few fundamental research findings related to halophytes have been applied to crop ...

The evolutionary innovation of root suberin lamellae contributed to the rise of seed plants
Nature Plants, 2023Seed plants overtook ferns to become the dominant plant group during the late Carboniferous, a period in which the climate became colder and dryer1,2. However, the specific innovations driving the success of seed plants are not clear. Here we report that the appearance of suberin lamellae (SL) contributed to the rise of seed plants.

Suberin lamellae of the onion root endodermis: their pattern of development and continuity
Botany, 2008In many plant species, suberin lamellae are deposited in the cells of the endodermis. Some cells near the xylem poles tend to remain without these lamellae and are known as “passage cells”. To develop a three-dimensional picture of the pattern of suberin lamella deposition, procedures were developed to isolate large pieces of onion endodermis and to ...

Development of Casparian bands and suberin lamellae in the endodermis of onion roots
Canadian Journal of Botany, 1992The endodermal Casparian band in onion (Allium cepa L.) roots is first evident 10 mm from the apex. It occupies a small region (20–30%) in the middle of the radial wall for a distance of 70 mm from the apex. However, with the development of suberin lamellae in most cells at greater distances from the root tip, the band expands symmetrically through ...

Building and breaking of a barrier: Suberin plasticity and function in the endodermis
Current Opinion in Plant Biology, 2021 Plant cells coated with hydrophobic compounds constitute a protective barrier to control movement of materials through plant tissues. In roots, the endodermis develops two barriers: the Casparian strips establish an apoplastic barrier and suberin ...

New Phytologist, 2022 Outer protective barriers of animals use a variety of bio-polymers, based on either proteins (e.g. collagens), or modified sugars (e.g. chitin).

Spatial and temporal deposition of suberin during maturation of the onion root exodermis
Botany, 2011 Suberin is a complex biopolymer composed of a poly(aliphatic) domain (SPAD) and a poly(phenolic) domain (SPPD). Suberin is typically confined to specialized cell types including root exodermal cells, but its synthesis in a maturing exodermis is still ...

The Casparian band of the exodermis of corn and onion roots matures further from the root tip than its counterpart in the endodermis. A complete suberin lamella in the exodermal cells usually develops about 10 mm proximal to the exodermal Casparian band.
