Induced plant responses to microbes and insects
Plants play a key role in the sustainability of life on earth. They fix the solar energy that drives nearly all living processes. As a result, plants are members of complex communities and interact both with antagonists and beneficial organisms. To defend themselves against harmful pathogens and insects, plants have evolved a sophisticated immune system to perceive alien organisms, and to trans...
متن کاملPlant Viruses and Insects
The principal families of insect vectors which cause the most damage to agricultural crops through the spread of plant diseases are in the order Hemiptera, and include the aphids, leafhoppers, delphacid planthoppers and whiteflies. Another important group of insect vectors found worldwide is the order Thysanoptera, the thrips. Other insects also spread plant diseases; however, aphids alone are ...
متن کاملThe effect of branching on cotton plant growth and development
Cotton plant development is usually predicted through a function of thermal time either at a daily step (Hanan and Hearn, 2003) or at a growth cycle (de Reffye et al., 1999). The GREENLAB model fits well to the architecture of some simple structured plants, e.g. pruned cotton (de Reffye et al., 1999) and maize (Guo et al., 2006). In the model, it is assumed a constant developmental rate and als...
متن کاملHost Plant Selection by Insects
Host plant selection by insects is often divided into „host plant finding‟ and „host plant acceptance.‟ While the two are easy to separate conceptually, in practice, they are really part of a continuum of three, rather than two, inextricably bonded links. However, the central link of host plant finding, thought previously to be governed by volatile chemicals, has, until now, proved intractable ...
متن کاملPlant Virus Transmission by Insects
Most plant viruses depend on vectors for their survival and spread. Most vectors are piercing-sucking insects that transmit plant viruses in either the circulative virus (CV) or noncirculative virus (NCV). NCV are carried on the lining cuticle of vectors stylets. CVs cross the vectors’ gut, move internally to the salivary glands (SG), cross the SG membranes to be ejected upon feeding. Transmiss...
