Methylobacterium species colonize plant surfaces and utilize methanol emitted from plants. Methylobacterium aquaticum strain 22A was isolated from a hydroponic culture of a moss, Racomitrium japonicum, and is a potent plant growth promoter. The complete genome sequencing of the strain confirmed the presence of genes related to plant growth promotion and methylotrophy.

Green onions grown in soil and hydroponic medium contaminated with Escherichia coli O157:H7 and Salmonella were found to take up the pathogens in their roots, bulbs, stems, and leaves. Pressure treatment at 400 to 500 MPa for 2 min at 20 to 40°C eliminated both pathogens that were internalized within green onions during plant growth.

Mangalore melon (Cucumis melo ssp. agrestis var. acidulus) is a non-dessert melon, extensively grown in the coastal districts of South India, but hardly known to rest World. Immature or mature fruits are used preparation delicious dishes such as vegetable stew, chutneys and curries. They appreciated for nutritional values, long shelf life biotic stress resistance. Seventy-nine accessions were c...

Phosphate (Pi), an essential macronutrient for growth and development of plant, is often limiting in soils. Plants have evolved an array of adaptive strategies including modulation of root system architecture (RSA) for optimal acquisition of Pi. In rice, a major staple food, RSA is complex and comprises embryonically developed primary and seminal roots and post-embryonically developed adventiti...

BACKGROUND Although the aerial parts of hydroponic Panax ginseng are reported to contain higher contents of total ginsenosides than those of roots, the isolation and identification of active metabolites from the aerial parts of hydroponic P. ginseng have not been carried out so far. METHODS The aerial parts of hydroponic P. ginseng were applied on repeated silica gel and octadecylsilane colum...

Renewable resources constitute a ‘limited infinity’, meaning that a limited amount is being produced, but for an infinite time.1 One of the most promising approaches to reduce the resource intensity is to use the existing biomass more efficiently: the biorefinery concept. It aims to use the complete biomass and all by-products emitted by the processes. Particularly the by-products of establishe...

Kůdela V., Krejzar V., Pánková I. (2010): Pseudomonas corrugata and Pseudomonas marginalis associated with the collapse of tomato plants in rockwool slab hydroponic culture. Plant Protect. Sci., 46: 1-11. Plant pathogenic species Pseudomonas corrugata and P. marginalis were detected and determined in collapsed tomato plants in rockwool slab hydroponic culture in southern Moravia, Czech Republic...

Salmonella enteritidis may have been transmitted through the hands of the vendors or from those of vendors who sold egg products in the vicinity. Although raw eggs and egg products have been implicated in contamination with Salmonella enteritidis the ability of this pathogen to survive for up to 7-14 days on the surface of many fresh fruits as in melons have been reported. Since, people of almo...

Iron deficiency chlorosis (IDC) in soybeans has proven to be a perennial problem in the calcareous soils of the U.S. upper Midwest. A historically difficult trait to study in fields, the use of hydroponics in a controlled greenhouse environment has provided a mechanism to study genetic variation while limiting environmental complications. IDC susceptible plants growing in calcareous soils and i...
