A rise in heavy metal contamination especially the rhizosphere affecting growth and yield of crops is a major concern. We aimed to study influence using calcium silicate (CS) ascorbic acid (AsA) supplements on lowering impact cadmium-induced toxicityin mung bean. Both alone or combination improved characteristics cadmium (Cd) stressed bean plants like root-shoot length fresh-dry weight. Leaf pi...

Landscape groundcover plants are a diverse group of trailing or spreading species that naturally form continuous soil coverage.Ground cover plants that were used in this study consisted of vegetative propagules of: Vinca minor L. ٬Variegatum’, Vinca minor L. ٬Green’, Oxalis brasiliensis G. Lodd, Trifolium repens L., Phyla nodiflora L. and Frankenia thymifolia Desf. The aim of this study was to ...

This perspective paper proposes that endogenous apoplastic fructans in fructan accumulating plants, released after stress-mediated cellular leakage, or increased by exogenous application, can act as damage-associated molecular patterns (DAMPs), priming plant innate immunity through ancient receptors and defense pathways that most probably evolved to react on microbial fructans acting as microbe...

Nitric oxide (NO), an endogenous signaling molecule, is involved in various physiological processes and stress responses in plants. In the present research, Pyrodwarf pear (Pyrus communis) rootstocks were grown by nutrient solution to investigate the effects of sodium nitroprusside (SNP) application as an NO donor at 0, 0.1, 0.5, and 1 mM levels on plant stress tolerance, content of ma...

Mitogen-activated protein kinase (MAPK) cascades have been identified in various signaling pathways involved in plant development and stress responses. We identified a drought-hypersensitive mutant (drought-hypersensitive mutant1 [dsm1]) of a putative MAPK kinase kinase (MAPKKK) gene in rice (Oryza sativa). Two allelic dsm1 mutants were more sensitive than wild-type plants to drought stress at ...

The experiment was conducted in factorial test based on a completely randomized design with three replications in greenhouse of Isfahan University of Technology of Iran. Lettuce seedlings were exposed separately to the exhaust emissions in three different exposure times (10, 20 and 30 days) and after the exposure time, their morphological, physiological and anatomical traits were measured and c...

copper is an essential micronutrient for plant growth which is involved in many metabolic processes. however excessive amounts of copper may cause environmental pollution. with an increase in the contamination of urban areas with heavy metals, more attention should be paid to the role of ornamental plants in removing pollutants from the soils. the effects of heavy metals on the growth parameter...

rainfall deficiency and the development of salinity in iran are the most important factors for using new salt and drought-resistant plants instead of conventional crops. kochia species have recently attracted the attention of researchers as a forage and fodder crop in marginal lands worldwide due to its drought and salt tolerant characteristics. this field experiment was performed at the salini...

Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM SA and then held at 25◦C up to 12 days. ...
