The Chromosomes of Lathyrus Tuberosus.

Spermidine Uptake by Mitochondria of Helianthus tuberosus.

In the present work evidence is provided that spermidine, a polyamine largely present in plant tissues, may be transported, at physiological concentrations, into the matrix space of mitochondria isolated from tubers of Helianthus tuberosus L. cv OB1 (Jerusalem artichoke). It is concluded that the movement of spermidine strictly depends on membrane potential, since it is drastically blocked by v...

Cooperative Evolutionary Strategy between the Bacteriome and Mycobiome

Nonhealing chronic wounds are all unique in origin and circumstance, and attempting to isolate a single etiology for the failure of a wound to heal is daunting. Wounds represent complex systems of multispecies fungal and bacterial biofilms. The survival strategies of interactive microbial communities have led to cooperative evolutionary strategies that culminate in biofilm formation. In microbi...

Two new epoxysteroids from Helianthus tuberosus.

Two new epoxy steroids, 5α,8α-epidioxy-22β,23β-epoxyergosta-6-en-3β-ol (1) and 5α,8α-epidioxy-22α,23α-epoxyergosta-6-en-3β-ol (2), and ten known steroids including (24R)-5α,8α-epidioxyergosta-6-en-3β-ol (3), (22E,24R)-5α,8α-epidioxyergosta-6,22-dien-3β-ol (4), (22E,24R)-5α,8α-epidioxyergosta-6,9(11),22-trien-3β-ol (5), β-sitosterol (6), sitost-5-en-3β-ol acetate (7), 7α-hydroxysitosterol (8), s...
