Geschäftsprozessmanagement wird seit mehreren Jahrzehnten in vielen Unternehmen und Organisationen für unterschiedliche Aufgaben von der Prozessmodellierung über die Prozessanalyse bis hin zur Prozessausführung mittels IT-Systemen eingesetzt. Parallel dazu sind in den letzten Jahren Werkzeuge zur Unterstützung des Personal Networking, des Informationsaustauschs und der Zusammenarbeit entstanden...

one of the method to clean up contaminated soil is growing a hyper accumulator plant which is named phytoremediation. some of  hyper accumulator plants are proper host for mycorrhizal fungi.in this relationship, fungus, consume a part of organic carbon from the plant and by developing its mycelium network help plant to uptake more mineral nutrients from the soil. by doing a greenhouse research ...

in order to understanding of the vam effects on functions and nutrition of the corn, a research was conducted in agricultural research center of safi abad, khouzestan. the experiment was carried out based randomized complete block design at four replications. the treatments contain mycorrhiza fungi and phosphorous includes: a: phosphorus according to soil test. b: vam + phosphorus according to ...

Auxin is implicated throughout plant growth and development. Although the effects of this plant hormone have been recognized for more than a century, it is only in the past two decades that light has been shed on the molecular mechanisms that regulate auxin homeostasis, signaling, transport, crosstalk with other hormonal pathways as well as its roles in plant development. These discoveries esta...

Plants are valuable sources of a vast array of chemical compounds like alkaloids, flavonoids, pigments, antimicrobials, pharmaceutical, etc. The majority of the compounds were produced by plants during different stages of cell, tissues and organ differentiation. Plant tissue culture is the process by which parts of plant can be grown in vitro condition in a sterile culture medium. The nutrient ...

Plant-derived terpenoids, long recognized as biomarkers, can help reveal the major taxonomic groups of land plants present in ancient environments, even if rocks and sediments do not preserve plant macroor microfossils. Previous studies have used simple dito triterpenoid ratios to reconstruct floral changes in the geologic past, but few have compared terpenoid ratios with estimates of floral co...

Induced defenses may evolve in natural plant populations where heritable variation in inducibility affects plant fitness. Although this has not been documented for any plant – parasite system, genetic variation in induction has been recently reported for several plant-parasite systems. Correlations between induction and fitness in variable parasite environments suggest that inducibility may ind...

Background and Aims. The largely Mississippian strata of the Kilpatrick Hills, located at the western end of the Scottish Midland Valley, enclose several macrofossil floras that together contain ca 21 organ-species of permineralised plants and ca 44 organ-species of compressed plants, here estimated to represent 25 whole-plant species (Glenarbuck = nine, Loch Humphrey Burn Lower = 11, Upper = s...

Sulphur isotope data from early Archaean rocks suggest that microbes with metabolisms based on sulphur existed almost 3.5 billion years ago, leading to suggestions that the earliest microbial ecosystems were sulphur-based1–5. However, morphological evidence for these sulphur-metabolizing bacteria has been elusive. Here we report the presence of microstructures from the 3.4-billion-year-old Stre...
