The study was conducted to evaluate the pathological changes of T. evansi infection in Swiss albino mice inoculated with buffalo isolate. Fifteen Swiss albino mice were used in present experiment divided in two groups consisting of six mice in each group. Group I is...
Background Trypanosoma evansi is a protozoan parasite that can infect a wide range of animals and is widespread around the world. In this study, we analyzed four fatal cases of T. evansi infection using clinical, parasitological, and molecular approaches. We also explored th...
Selection of proper shoot of scion and rootstock are important for grafting sucess
Grape cultivation, in India, is dependent on a narrow range of table grape varieties, with more than 70 per cent cultivated area in Maharashtra alone, followed by Karnataka and Tamil Nadu. Therefore, to increase the scope of area extension under grape cultivation,...
Foot rot disease, also known as “quick wilt” caused by Phytophthora capsici Leonian in black pepper (Piper nigrum L.) often leads to mortality of the infected plants. No cultivated variety is completely resistant, though a few varieties show field tolerance. Plants in all growth...
Ginger (Zingiber officinale Roscoe; 2 n = 22) is an important spice crop recognized for its medicinal benefits and pharmacological activities. The crop is said to have a narrow genetic base in the cultivated gene pool due to hinderance in sexual recombination. Polyploid ...
Bacterial strains were isolated from turmeric rhizosphere and 18 of them exhibited plant growth promoting traits and ability to solubilize mineral. They also showed the ability to concurrently suppress the growth of multiple fungal phytopathogens under in vitro assay. An isolate of Baci...
Ginger is one of the most commonly consumed dietary spices with significant pharmacological and physiological activities. The occurrence of a distinctive type of leaf blight with characteristic reddish-brown lesions along the leaf margins and distal end of the leaves was observed on gin...
Cucumber mosaic virus (CMV) infects a large number of plant species including Piper nigrum L. and related species. As natural resistance to CMV is absent in Piper spp., the study was undertaken to produce transgenic P. nigrum plants harboring the complete coat protein (CP) gen...
A field study was conducted at ICAR-Indian Institute of Spices Research, Regional Station, Madikeri, Karnataka during 2018 and 2019 to evaluate elite lines of small cardamom (Elettaria cardamomum Maton) for capsule yield, essential oil constituents, photosynthesis and antioxidant enzyme activities...
A study was conducted to choose a suitable host and substrate for Arbuscular Mycorrhizal (AM; Rhizophagus sp.) inoculum multiplication. Two plant species, maize (Zea mays L.), and bajra napier hybrid (BNH) were examined for mass multiplication of the AM fungus Rhizophagus sp. The i...
Cardamom thrips, Sciothrips cardamomi Ramk. (Thysanoptera: Thripidae) cause huge economic losses to cardamom, Elettaria cardamomum (L.) Maton., a high-value spice crop, in all growing regions worldwide. To date, the pest is managed by synthetic pesticides, which results in harmful residues in...
Zinc (Zn) deficiency is widespread in plants and molecular mechanism of uptake and transport within organelles is unclear. A novel Zn transporter gene was identified and characterized from turmeric (Curcuma longa L.) and expression analyzed in presence of zinc oxide (ZnO) and Bacillus...
Statistical tools such as analysis of variance, correlation, path coefficient analysis, Scott-Knott test and principal component analysis were used in the present study to characterize black pepper verities/hybrids for spike and berry traits. ANOVA indicated that fifteen traits under study w...
An experiment was conducted at IISR, Kozhikode to study the effect of foliar application of chemical elicitors, namely, chitosan (100, 200 and 500 ppm), phenylalanine (0.1, 1 and 10 mM) and salicylic acid (0.01, 0.1 and 1 mM) on volatile constituents of turmeric rhizome essent...
Background: In the presented work, we studied the effect of foliar spray of elicitors namely chitosan, phenylalanine and salicylic acid sans any stress treatment on physiological and quality parameters in turmeric genotypes. Methods: Feld experiment was undertaken under rainfed ...
Sweet Potato is an important food crop, and its production is affected by environmental stresses, including high temperature. The gene expression patterns and molecular responses in different tissues of sweet potato under high temperature stress were studied using microarray data sets. Analy...
Thirty cassava accessions, including released and pre-release varieties in India were selected for morphological, statistical and molecular analysis to evaluate their genetic divergence. Based on ANOVA (Analysis of Variance), significant differences were observed in thirty genotypes for the fifteen ch...
Soft rot and bacterial wilt are the major production constraints in ginger worldwide. As these pathogens are transmitted primarily through ginger rhizomes that are widely used as planting materials, effective and sensitive techniques are required for reliable and accurate diagnosis. In the...
An efficient direct in vitro plant regeneration protocol has been established for medicinally important red-colored ginger (Zingiber officinale Rosc.) genotypes, namely, northeast red ginger and exotic red ginger. Shoot, root initiation, and growth response of these two genotypes to five differen...
Drying of freshly harvested green pepper (Piper nigrum) was performed in a reverse air flow mechanical dryer (RRLT-NC – 101). Fresh and blanched pepper of varieties, Sreekara and Panniyur-1 were dried at 50°C, 55°C, and 60°C. Blanching was done by dipping in boiling water for&...
In this study, a multiplex PCR assay was developed to detect Phytophthora, Pythium and Fusarium infecting black pepper. Genus-specific primers were designed from the conserved region of ITS and a multiplex PCR was optimized by manipulating the annealing temperature and primer as well...
Black pepper (Piper nigrum) of Sreekara variety was dried in an agricultural waste fired reverse flow dryer and thin layer drying characteristics of blanched and unblanched pepper was studied. Blanching was done by dipping in boiling water for 1 min. The experimental data for ...
Polishing of turmeric is an important post harvest operation done after drying to improve the surface colour and to obtain a smooth surface finish. Turmeric (variety IISR Prathiba) was cleaned and cured for 1 h in a steam operated turmeric boiler and one batch was dried...
Foot rot disease caused by Phytophthora capsici is a serious threat to black pepper cultivation in India and globally. High diversity exists among the Phytophthora isolates of black pepper and hence detailed investigations of their morphology and phylogenetic taxonomy were carried out i...
