Journal of Plant Physiology & Pathology is a peer-reviewed scholarly journal and aims to publish the most complete and reliable source of information on the discoveries and current developments in the mode of original articles, review articles, case reports, short communications, etc. in all areas of plant physiology & pathology and making them available online freely without any restrictions or any other subscriptions to researchers worldwide.
Journal of Plant Physiology & Pathology focuses on the topics include, but not limited to: Molecular Plant Pathology, Phytopathology, Plant Parasite Interactions, Transgenic Research, and Experimental Botany.
The Journal is using standards and quality in review process. Review processing is performed by the editorial board members of Journal of Plant physiology & Pathology or outside experts; at least two independent reviewers approval followed by editor approval is required for acceptance of any citable manuscript. Authors may submit manuscripts and track their progress through the system, hopefully to publication. Reviewers can download manuscripts and submit their opinions to the editor. Editors can manage the whole submission/review/revise/publish process.
Impact of the Arbuscular Mycorrhizal Fungi and Bacteria on Biocontrol of White Root Rot in Fruit Seedlings
This currently investigation aimed to evaluate the synergistic effect of the arbuscular mycorrhizal fungus (AMF), Gigaspora margarita, and the bacteria Paenibacillus rhizospherae on the alleviation of white root rot of Japanese apricot (Prunus mume) seedlings. Three experiments were carried out to evaluate that. In the first one, J.apricot “Nanko” seedlings were inoculated with (5, 10 and 20 %)inoculums containing the pathogen Rosellinia necatrix (NRBC 5954). In the second experiment the same kind of seedlings were submitted to four treatments: Control (C), AMF (A), Bacteria (B), AMF+Bacteria (A+B). Disease severity, root infection and AMF colonization were evaluated in this experiment.
Soil-Borne Plant Pathogens Associated to Decline of Grapevine Grown in Greenhouse
The purpose of the study was to determine which fungal species were associated with a decline in greenhouse grown grapevine (“Fujiminori”). Two species of fungi, characterized as soil-borne plant pathogens were isolated from roots. The fungi were identified by DNA sequencing methods and by their morphology. The fungi were identified as Cylindrocarpon destructans (FJMB2) and Fusarium Oxysporum (FJBM3) according to the DNA sequences and similarities after BLAST search.
Management of Plant-parasitic Nematodes by the Use of Botanicals
Plant-parasitic nematodes are causing great damage to agricultural and horticultural crops. Hence, biopesticides of botanical origin have become focus of attention today for facing the nematode problems in an eco-friendly manner. The use of botanical pesticides is now emerging as one of the prime means to protect crops. In India, botanical pesticides are available in many plants for which deep search and testing is required as many of them are still unexplored.
Peroxidase and Polyphenoloxidase Activities as Biochemical Markers for Biocontrol Efficacy in the Control of Tomato Bacterial Wilt
We have studied the effect of certain bioagents for the control of bacterial wilt of tomato under greenhouse and field conditions and the effect of these bioagents in induction of some enzyme activity in planta e.g. Peroxidase (PO) and polyphenoloxidase (PPO). Under greenhouse conditions the effect of Pseudomonas putida and P. fluorescens, and their combination were studied, and we found that both of them reduced the disease 60 and 66.67%, respectively and the combination treatment reduced the disease 53.33%. Also under field conditions P. putida was the best in reduction of the disease followed by the combination and then P. fluorescens. The P. fluorescens treatment recorded the highest percent yield increase in the two trails.
Phytoaccumulation of Chromium and Copper by Mentha spicata L.
This paper reports a study of heavy metal absorption by Mentha spicata. M. spicata was grown in garden soil. The soil was treated with different concentrations (20 mg/l, 40 mg/l, 60 mg/l and 80 mg/l)of chromium and copper solutions. The effect of the application of the above two heavy metals was studied after 10 days of the treatment.Chromium and copper exerted toxic effects on the growth and physical parameters of Mentha spicata. M. spicata functioned as a hyper accumulator of chromium and copper. The results indicated that the reduction of growth parameters was inversely related to concentration of the heavy metals.
Modulation of Oxidative Stress Responsive Enzymes and Non-Enzymatic Components by Excess Nickel in C. lanatus Var.Fistulosus
This study focuses on induction of oxidative stress and antioxidative defense mechanism on exposure to excess nickel (Ni) in C. lanatus L. var. fistulosus (C. lanatus). Plants grown in refined sand and treated with nickel (as nickel sulphate) at 0.0001 (control), 0.05, 0.1, 0.2, 0.4 and 0.5 mM. The primary site of Ni toxicity was shoots where young leaves developed interveinal chlorosis along with marked reduction in growth, after nine days of excess Ni supply (d 42). At excess Ni (>0.05 mM), biomass, concentrations of chlorophyll, carotenoides, iron, Hill reaction activity, and activity of catalase were decreased, whereas activity of peroxidase, ascorbate peroxidse, superoxide dismutase, proline and lipid peroxidation in leaves increased
