OMICS Publishing Group operates in tune with the need for open access that is being constantly felt with passage of time by funding bodies and the associated research institutions alike. The Finch Report, developed by a committee chaired by Dame Janet Finch in Great Britain was accepted by the government in mid of 2012. The findings suggest strong need to enable more people to read and use the publications, particularly those featuring publicly funded research.
Plant parasitic nematodes are gaining considerable importance worldwide due to their devastating effects on crops leading to major economic downturn. Nematodes are attracted to plant roots via soluble and gaseous attractants produced by root itself or by attendant rhizosphere microorganisms. Just how nematodes move through soil to locate plant roots is poorly understood but is of considerable importance to predict the important role nematode play in soil ecosystems. Investigation was conducted to compare and contrast the differences in host recognition of root-knot nematodes, Meloidogyne graminicola and M. incognita on rice and tomato in pluronic gel medium resembling natural three dimensional soil environment.
A significant preference of M. incognita for tomato and M. graminicola for rice was observed in attraction bioassay reassured by penetration and development study in different host plants. Thus, either the blend of attractants and repellents are different in good and poor hosts; or, relatively long range attractants along with shorter range repellents might affect nematode movement patterns. Therefore, plant volatiles like small lipophilic molecules emitted by root exudates of tomato and rice were isolated through solid phase extraction to investigate their effect on root-knot nematodes. The semiochemicals present in those molecules negatively influenced the behavior of M. incognita and M. graminicola in stylet thrusting, motility and mortality bioassay. Therefore, it is proposed that lipophilic molecules present in both tomato and rice root exudates play important roles during the interaction of Meloidogyne spp. with their host plants and that they might exert a repellent, or allellopathic effect on these nematodes.
Horticulture is the science, art, technology and business involved in intensive plant cultivation for human use. It is practiced from the individual level in a garden up to the activities of a multinational corporation. It is very diverse in its activities, incorporating plants for food (fruits, vegetables, mushrooms, culinary herbs) and non-food crops (flowers, trees and shrubs, turf-grass, hops, grapes, medicinal herbs). It also includes related services in plant conservation, landscape restoration, landscape and garden design/construction/maintenance, horticultural therapy, and much more. This wide range of food, medicinal, environmental, and social products and services are all fundamental to developing and maintaining human health and well-being.
