Sedentary plant-parasitic cyst nematodes are biotrophs that cause significant losses in agriculture. Parasitism is based on modifications of host root cells that lead to the formation of a hypermetabolic feeding site (a syncytium) from which nematodes withdraw nutrients. The host cell cycle is activated in an initial cell selected by the nematode for feeding, followed by activation of neighbori...
The sexual reproductive process of Achlya ambisexualis, a heterothallic form belonging to a well known and widely distributed genus of saprophytic aquatic fungi, is initiated and coordinated by means of specific substances (Raper, 1939, a). Four of these substances have been demonstrated (Raper, 1939, b, 1940) in the r&es of initiators and coordinators of the various stages in the sexual proces...
Transcription factors play a key role to enable plants to cope with abiotic stresses. DREB2 regulates the expression of several stress-inducible genes and constitutes major hubs in the water stress signalling webs. We cloned and characterized a novel gene encoding the FpDREB2A transcription factor from Fraxinus pennsylvanica, and a yeast activity assay confirmed its DRE binding and transcriptio...
An extraordinary progress has been made over the last two decades on understanding the components and mechanisms governing plant innate immunity. After detection of a pathogen, effective plant resistance depends on the activation of a complex signaling network integrated by small signaling molecules and hormonal pathways, and the balance of these hormone systems determines resistance to particu...
persian shallot, also called leek (allium ampeloprasum), is a monocotyledon plant of the lily family (liliaceae). it belongs to the genus allium, has a characteristic taste and morphological features, and is considered as one of the oniony vegetables. this research was conducted with the purpose of obtaining optimal conditions for tissue culture of persian shallot and of comparing calli and lea...
Ethylene is a gaseous plant hormone that most likely became a functional hormone during the evolution of charophyte green algae, prior to land colonization. From this ancient origin, ethylene evolved into an important growth regulator that is essential for myriad plant developmental processes. In vegetative growth, ethylene appears to have a dual role, stimulating and inhibiting growth, dependi...

Background and objectives: Ferula assa-foetida is an herbaceous perennial plant which belongs to Apiaceae family. It is native to the east and central parts of Iran. This old traditional medicine has been used as antispasmodic, carminative, expectorant, laxative, sedative, stimulant, emmenagogue and vermifuge. In addition to the several therapeutic effects of the plant...
(2015) Phosphoproteomics-based peptide ligand-receptor kinase pairing. Commentary on: " A peptide hormone and its receptor protein kinase regulate plant cell expansion " .
Evolution has provided at least two particularly successful independent solutions to the problems of multicellularity - animals and higher plants. An obvious requirement for successful multicellularity is communication between different parts of the organism, both locally, for example between neighbouring cells, and over very long distances. Recent advances in understanding hormone signalling n...
