I. The apparent digestibilities for chicks, operated on so as to allow separate collection of urine and faeces, of the nitrogen in a heat-damaged cod flour (C35) and of a control, freezedried cod muscle (Cz3) were 77 and 90 yo respectively. 2. The differences are similar to those found for rats in earlier work and considerably smaller than the differences found in nutritional value of the mater...

Several mammalian, chicken, and mosquito cells grown in vitro take up tritiated dolichol supplied to the incubation medium. The extent of labelling varied markedly between different cell cultures. After 20 h incubation most of the dolichol taken up was unchanged and the major product of metabolism of dolichol was identified as its fatty acid esters. Green-monkey kidney cells were tested with 8 ...

It has been shown that thioredoxin (Trx) in a reduced form binds to and inhibits apoptosis signal-regulating kinase 1 (ASK1). Apoptotic stimuli such as tumor necrosis factor (TNF) and reactive oxygen species (ROS) activate ASK1 in part by oxidizing Trx (forming intramolecular disulfide between C32 and C35) to release Trx from ASK1. In the present study, we examined if Trx affects ASK1 protein s...

UNLABELLED A better understanding of how bacteria resist stresses encountered during the progression of plant-microbe symbioses will advance our ability to stimulate plant growth. Here, we show that the symbiotic system comprising the nitrogen-fixing bacterium Bradyrhizobium diazoefficiens and the legume Aeschynomene afraspera requires hopanoid production for optimal fitness. While methylated (...

In Citrus, flower induction represents the transition from vegetative to reproductive growth. The regulation of is mainly triggered by exposure low temperatures and water-deficit stress, which activates signaling cascade leading an increased expression citrus orthologs FLOWERING LOCUS T (CiFT). this study, relationship between rootstock under Mediterranean field conditions was investigated moni...
