Drymaria cordata (L.) Willd. ex Roem. & Schult. commonly known as ‘West Indian Chick weed’ is a potential herb used in traditional medicine the treatment of many ailments. The main active principles therapeutically are drymaritin and isovitexin. Arbuscular mycorrhizae (AM) symbiotic associations between plants soil fungi that play vital role plant growth development well quality. In present...

The impact of whitefly-transmitted begomoviruses (Geminiviridae) on tomato yields depends on plant age at time of infection, and is greatest during the first 5 weeks after germination (critical period). A preventative strategy designed to minimize contact between the vector and the tomato plant by masking the crop with living ground covers during the critical period was promoted among small-sca...

UNLABELLED PREMISE OF THE STUDY To understand the origins of C(4) grasslands, we must have a better interpretation of plant traits via phylogenetic reconstruction. Muhlenbergiinae, the largest subtribe of C(4) grasses in Mexico and the southwestern United States (with 176 species), is taxonomically poorly understood. • METHODS We conducted a phylogenetic analysis of 47 genera and 174 speci...

The generalized state space of a commutative C *-algebra, denoted S H (C(X)), is the set of positive unital maps from C(X) to the algebra B(H) of bounded linear operators on a Hilbert space H. C *-convexity is one of several non-commutative analogs of convexity which have been discussed in this context. We show that a C *-extreme point of S H (C(X)) satisfies a certain spectral condition on the...
