Latest work with IntechOpen by Sarwan Kumar

Brassica crops, including broccoli, cauliflower, cabbage, and mustard, are among the most important crops worldwide with oilseed Brassica among the largest traded agricultural commodities. They play a vital role in agriculture, horticulture, and human nutrition. The health-promoting and disease-preventing properties of Brassica vegetables are well documented, and their nutritional value makes them an essential part of a balanced diet. Brassica - Recent Advances provides a comprehensive overview of the recent research on Brassica crops. The book covers such topics as the breeding of Brassica crops, agronomic practices, pest management, and plant secondary metabolites. It is an essential resource for researchers, students, and professionals interested in Brassica crops and their applications.

Host Plant Resistance in Brassicaceae against Aphids

By Neha Panwar, Sathya Thirumurugan and Sarwan Kumar

This chapter deals with brassica plants and their resistance to sucking pests—aphids. Brassica plants are known to synthesize a number of plant secondary metabolites which impart resistance to insect-pests and diseases. Aphids are known to feed primarily on sieve elements. The sieve elements in vascular bundles of angiosperms are important channels for nutrition. They are the channels of transport of photoassimilates from source to the sink. Because of the high nutrition content of the sap inside sieve elements, they are the target for many insect-pests and bacterial and fungal pathogens. Aphids are one such group of insects which target SE elements of phloem for nutrition. They are among the most important insect pests in agriculture particularly serious in temperate and sub-tropical climates. In addition to direct damage by feeding as well as toxic effects of saliva, the withdrawal of nutrients is detrimental to plant growth and development. In addition to this, aphids also cause indirect damage to plants by acting as vectors of plant pathogenic viruses. Furthermore, honeydew excreted by aphids provides suitable substrate for sooty molds that interfere with normal plant photosynthesis. In this chapter work on host plant resistance in Brassica plants against aphids has been reviewed.
