The combinatorial interaction of a receptor kinase and a modified CLE peptide is involved in several developmental processes in plants, including autoregulation of nodulation (AON), which allows legumes to limit the number of root nodules formed based on available nitrogen and previous rhizobial colonization. Evidence supports the modification of CLE peptides by enzymes of the hydroxyproline O-...

a study of insect digestive enzymes makes sense given that the gut is the major interface between the insect and its environment. an understanding of gut and digestive enzyme function is essential when advanced methods of insect management such as application of enzyme inhibitors and transgenic plants are developed to control insect pests. the aim of the current research project was to study mi...

sunn pest is considered as the most important insect pest of wheat and barley in iran. different studies have shown that various biotic and abiotic factors affect sunn pest populations. these factors can influence the population density of the pest which in turn can play a role in the control of the pest. in this study the relationship between sunn pest population fluctuations and climatic cond...

For the synthesis of biocomposite materials for useful applications, it becomes necessary to modify the surface of natural fibers through chemical treatments. Morphology, structure and properties of natural fibers have an obvious effect on the mechanical properties of the biocomposite materials. It is thus necessary to know the morphology, thermal stability and crystalline behavior of original ...

Plant parasitic nematodes, Meloidogyne javanica in particular, cause significant yield losses in sugarcane crops in South Africa. The chemicals at present available for nematode control are expensive and potentially detrimental to the environment. It has been reported that various types of crops reduce the numbers of plant parasitic nematodes. Seven green manure crops (sunn hemp, marigold, oats...

field experiments were conducted to determine the optimum application rate of sunn hemp crotalaria juncea leaf residue in the management of meloidogyne incognita on tomato. sunn hemp applied at rates of 0 (control), 2, 4 and 6 kg/ha showed a varied effect on second stage juveniles of m. incognita. there were no differences in plant height and stem girth. the 6 kg/ha treatment reduced the m. inc...

The genus Eurygaster Laporte, 1833 includes ten species five of which inhabit the European part of Russia. The harmful species of the genus is E. integriceps. Eurygaster species identification based on the morphological traits is very difficult, while that of the species at the egg or larval stages is extremely difficult or impossible. Eurygaster integriceps, E. maura, and E. testudinaria diffe...

One of the most important forms of preharvest damage to wheat is caused by sunn pests. The insects insert their mouth parts into the immature grain and while injecting their saliva suck the milky juices. Flour from damaged wheat results in low baking performance due to the bug proteolytic enzymes’ injected which cause the breakdown of gluten structure in the dough. In the present study three wh...

Wang, Q., Y. Li, Z. Handoo, and W. Klassen. 2007. Influence of cover crops on populations of soil nematodes. Nematropica 37:79-92. A pot experiment was carried out in south Florida to elucidate suppressive or antagonistic effects of several cover crops grown in rotation on soil nematode populations. The crops were two marigolds, Tagetes patula L. ‘Dwarf Double French Mix’ (MDF), and Tagetes pat...
