Outside the stele lies the endodermis, which is the innermost cell layer of the cortex. The concept of the stele was developed in the late 19th century by French botanists P. E. L. van Tieghem and H. Doultion as a model for understanding the relationship between the shoot and root, and for discussing the evolution of vascular plant morphology. [2]
The Merneptah Stele, also known as the Israel Stele or the Victory Stele of Merneptah, is an inscription by Merneptah, a pharaoh in ancient Egypt who reigned from 1213 to 1203 BCE. Discovered by Flinders Petrie at Thebes in 1896, it is now housed at the Egyptian Museum in Cairo .
The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. [ citation needed ] Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues ...
Common spot on strawberry is a polycyclic disease, and under favorable conditions it will continue to reinfect the host and surrounding plants. The fungus overwinters as mycelium, sclerotia, and perithecia in infected leaf tissues.
Examples of polycyclic groups include finitely generated abelian groups, finitely generated nilpotent groups, and finite solvable groups. Anatoly Maltsev proved that solvable subgroups of the integer general linear group are polycyclic; and later Louis Auslander (1967) and Swan proved the converse, that any polycyclic group is up to isomorphism a group of integer matrices.

Limestone Stele of Canaanite God Mekal, 13th C. BCE. One of the steles, discovered in 1928, [10] states that the temple was dedicated to “Mekal, the god, the lord of Beth Shean”; [11] an otherwise unknown Canaanite god – the stele itself is our main source of knowledge about Mekal.
Baal with Thunderbolt or the Baal stele is a white limestone bas-relief stele from the ancient kingdom of Ugarit in northwestern Syria. The stele was discovered in 1932, about 20 metres (66 ft) from the Temple of Baal in the acropolis of Ugarit, during excavations directed by French archaeologist Claude F. A. Schaeffer .
In the field of organic chemistry, a polycyclic compound is an organic compound featuring several closed rings of atoms, primarily carbon. [1] These ring substructures include cycloalkanes , aromatics , and other ring types.
