In order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (Foeniculum vulgare Miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. Arbuscular mycorrhizal fungi (strain Sebacina vermifera) and phosphate dissolving bacteria (genera Peseudomonas) were applied as ...

Preconditioning of plant material prior to cryopreservation is beneficial for increasing the survival of plant tissues. Pretreatment of plant cells and tissues can be divided into three categories. Cultural pretreatments may involve growth medium, cold acclimation or consideration of the plant part used. Chemical treatments may be osmotic or penetrating cryoprotectants. Desiccation treatments m...

In order to identify the endophytic fungi of stone fruit trees in West Azarbaijan province (Iran), healthy tissues were collected from various regions. For isolation of endophytic fungi, plant tissues were primarily washed with tap water, then surface sterilized by rinsing in 75% ethanol for 1 minute, followed by 5 minutes in 3% sodium hypochlorite (active ingredient). Disinfested pieces were t...

For many plant species, nutrient availability induces important anatomical responses, particularly the production of low-density tissues to the detriment of supporting tissues. Due to the contrasting biomechanical properties of plant tissues, these anatomical responses may induce important modifications in the biomechanical properties of plant organs. The aim of this study was to determine the ...

To understand many aspects of the metabolism of complex plant structures such as leaves, fruit and roots it is important to understand how metabolic processes are compartmentalized between tissues. The aim of this article is to show how immunohistochemistry, in conjunction with biochemical and physiological studies, is useful in understanding both the function of an enzyme in a tissue and metab...

known acid phosphatase and acid pyrophosphatase, a potent alkaline pyrophosphatase, active only in the presence ofadded Mg2+, was found to be present in all vegetable tissues tested. Fresh plant products showed more alkaline pyrophosphatase activity than the stored products. The richest sources are green leaves, which also contain large amounts of acid pyrophosphatase. However, some leaves like...

Plant surfaces, colonized by numerous and diverse bacterial species, are often considered hot spots for horizontal gene transfer (HGT) between plants and bacteria. Plant DNA released during the degradation of plant tissues can persist and remain biologically active for significant periods of time, suggesting that soil or plant-associated bacteria could be in direct contact with plant DNA. In ad...
