Concentrations of soluble soil sugars, soluble phenolic acids, and free amino acids were measured in three forest communities at the FACTS-II Aspen FACE Site near Rhinelander, WI, in order to better understand how elevated atmospheric CO2 and O3 are influencing soil nutrient availability and cycling. Sugars, phenolic acids, and amino acids are mostly derived from plant and microbial processes, ...

introduction   heavy metal contamination has disastrous effects on plant productivity and threatens human and animal health. among metals, cadmium (cd) is commonly released into the environment from industrial processes. cd is known to cause cellular damage in plants by producing oxidative stress via the over-production of reactive oxygen species (ros). to combat oxidative damage, plants have d...

effect of different co2 concentrations on sucrose metabolizing enzymes and on carbohydrate metabolism was studied for eight blackgram (vigna mungo l. hepper) genotypes grown in open top chambers under ambient (380 µmol mol-1) vs. elevated co2 (550 and 700 µmol mol-1) levels. the higher acid invertase activity over neutral invertase indicated the major role of acid invertase in sucrose breakdown...

in a pot experiment the effect of water stress on the proteins and proline amino acid content of jam, kurosh, pirooz chickpea cultivars (cicer arientinum) were evaluated using a complete block design with factorial treatments inducing cultivars and watering periods, three, six and nine day intervals in three replications. soluble protein and free proline content of the leaf and the root were me...

seeds deterioration is a natural phenomenon that occurs in all seeds and leading to gradual decline of seed viability during storage. however, the rate at which seeds age depends upon their physiological status, genetic constitution and storage conditions. in the present study we the examined relationship between accumulation of reducing and non-reducing of sugars, soluble protein, the activity...

Abstract Blueberries ( Vaccinium corymbosum L.) are cultivated worldwide and represent an important asset for the Portuguese economy. Pathogen infection water deficiency known to affect crops productivity worldwide, thus limiting plant yield or fruit quality. Diaporthe is a cosmopolitan genus comprising pathogens endophytes, that may switch their behavior pathogenic phase when host under enviro...
