Source-to-sink transport of sugar is one of the major determinants of plant growth and relies
on the efficient and controlled distribution of sucrose (and some other sugars such as …

The peritrophic matrix (PM) is a chitin and glycoprotein layer that lines the invertebrate
midgut. Although structurally different, it is functionally similar to the mucous secretions of the …

Plants respond to insect herbivory with responses broadly known as direct defenses, indirect
defenses, and tolerance. Direct defenses include all plant traits that affect susceptibility of …

Lectins are carbohydrate binding (glyco) proteins which are ubiquitous in nature. In plants,
they are distributed in various families and hence ingested daily in appreciable amounts by …

Due to the high content of nutrient, sieve tubes are a primary target for pests, eg, most
phytophagous hemipteran. To protect the integrity of the sieve tubes as well as their content …

Phloem feeding involves unique biological interactions between the herbivore and its host
plant. The economic importance of aphids, whiteflies, and other phloem‐feeding insects as …

Annually, the cost of insect pest control in agriculture crosses billions of dollars around the
world. Until recently, broad-spectrum synthetic pesticides were considered as the most …

Transgenic wheat plants containing the gene encoding snowdrop lectin (Galanthus nivalis
agglutinin; GNA) under the control of constitutive and phloem-specific promoters were …

Insecticidal effects of three plant-derived genes, those encoding snowdrop lectin (GNA),
bean (Phaseolus vulgaris) chitinase (BCH) and wheat α-amylase (WAI), were investigated …

The sap sucking insects (Hemiptera), which include aphids, whiteflies, plant bugs and stink
bugs, have emerged as major agricultural pests. The Hemiptera cause direct damage by …
