Soil-borne pathogens such as Verticillium species, invade into the roots of many herbaceous and woody hosts. The xylem environment supplies these with a continuous flow nitrogen-rich nutrition. Detailed quantitative increases in amino acids stems, petioles, leaflets young tomato plants infected Verticillium. albo-atrum causal agent wilt disease, are described this paper for first time. Results ...

Petioles of the plant piper betle-bengal variety have been subjected for extraction employing standard procedure and the crude extract obtained has been evaluated for its diastase like activity and other physico-chemical properties to investigate further its possible biological and pharmacological activities.

A virulent Pseudomonas viridiflava-related bacterium has been identified as a new pathogen of soybean, one of the most important crops worldwide. The bacterium was recovered from forage soybean leaves with dark-reddish spots, and damage on petioles and pods was also observed. In contrast, common bean was not affected.

Crude enzyme extract obtained from the petioles of the plant piper betel- Bengal variety as been evaluated for various physico-chemical studs such as estimation of protein content, thin layer chromatography, optical activity and tests for the presence of thiol groups, disulphide and peptide linkages and the results are discussed.

Aim: Stem gall diseases have become major economic significance. The disease manifests itself in the form of galls on stem, branches, leaves, petioles and fruits, causes 15-20 per cent yield loss and deteriorates quality of seeds. Quantitative biochemical changes are required to determine for development of resistant variety against stem gall Methodology: Stem gall symptoms were regularly obser...

Verticillium longisporum is a soil-borne vascular pathogen that causes reduced shoot growth and early senescence in Arabidopsis (Arabidopsis thaliana). Here, we report that these disease symptoms are less pronounced in plants that lack the receptor of the plant defense hormone jasmonic acid (JA), CORONATINE INSENSITIVE1 (COI1). Initial colonization of the roots was comparable in wild-type and c...

Enhancing nutrient uptake and the subsequent elemental transport from the sites of application to sites of utilization is of great importance to the science and practical field application of foliar fertilizers. The aim of this study was to investigate the mobility of various foliar applied zinc (Zn) formulations in sunflower (Helianthus annuus L.) and to evaluate the effects of the addition of...

Quantitative resistance against Leptosphaeria maculans in Brassica napus is difficult to assess in young plants due to the long period of symptomless growth of the pathogen from the appearance of leaf lesions to the appearance of canker symptoms on the stem. By using doubled haploid (DH) lines A30 (susceptible) and C119 (with quantitative resistance), quantitative resistance against L. maculans...
