Combination Effect of Piriformospora indica, Chilling and Gibberellic Acid on Seed Germination Traits of Kelussia odoratissima Mozaff.
Kelussia odoratissima Mozaff. belonging to the Apiaceae family, is well known for its medicinal and nutritional importance, endemic to Iran. Seed dormancy is a major problem present in Kelussia odoratissima leading to low germination percentage; thus, improvement of seed germination and breaking seed dormancy is important. Piriformospora indica, a root-colonizing endo...
متن کاملSpore Germination and Protonemal Development of Dolichomitriopsis diversiformis
Dolichomitriopsis diversiformis is an endemic and threatened moss in eastern Asia. In vitro culture and light microscopic observation were employed to study its developmental process from spore germination to the formation of young gametophyte, as well as effects of light and temperature on its spore germination and protonemal development. Microscopic observations revealed that its spores were ...
متن کاملAxenic Culture of the Mycobiont of Xanthoma Parietina in Different Nutritive Media: Effect of Carbon Source in Spore Germination
Xanthoria parietina mycobiont was isolated and cultured under axenic conditions. The development of the fungi in aposymbiotic culture depended on the carbon source present in the nutritive medium. The highest development was obtained with 4% glucose in LBM. Nevertheless, the major yield of spore germination was in BBM medium. When the sporulation process was carried out in LBM (without contamin...
متن کاملCortex peptidoglycan lytic activity in germinating Bacillus anthracis spores.
Bacterial endospore dormancy and resistance properties depend on the relative dehydration of the spore core, which is maintained by the spore membrane and its surrounding cortex peptidoglycan wall. During spore germination, the cortex peptidoglycan is rapidly hydrolyzed by lytic enzymes packaged into the dormant spore. The peptidoglycan structures in both dormant and germinating Bacillus anthra...
