Desiccation tolerance mechanisms in the green lineage and beyond

New Phytologist, EarlyView.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

Combining Local and Von Neumann Regular Rings [PDF]

Communications in Algebra, 2004
All rings R considered are commutative and have an identity element. Contessa called R a VNL-ring if a or 1 − a has a Von Neumann inverse whenever a ∈ R.

Von Neumann regular graphs associated with rings [PDF]

Discrete Mathematics, Algorithms and Applications, 2018
Let [Formula: see text] be a ring with nonzero identity. By the Von Neumann regular graph of [Formula: see text], we mean the graph that its vertices are all elements of [Formula: see text] such that there is an edge between vertices [Formula: see text] if and only if [Formula: see text] is a Von Neumann regular element of [Formula: see text], denoted

Simple flat Leavitt path algebras are von Neumann regular [PDF]

Communications in Algebra, 2019
For a unital ring, it is an open question whether flatness of simple modules implies all modules are flat and thus the ring is von Neumann regular. The question was raised by Ramamurthi over 40 years ago who called such rings SF-rings (i.e.
