Exploring the co-operativity of secretory structures for defense and pollination in flowering plants
In flowers multiple secretory systems cooperate to deliver specialized metabolites to support specific roles in defence and pollination. The collective roles of cell types, enzymes, and transporters are discus...

Open AccessAutomated video tracking of thrips behavior to assess host-plant resistance in multiple parallel two-choice setups
Piercing-sucking insects cause severe damage in crops. Breeding for host-plant resistance can significantly reduce the yield losses caused by these insects, but host-plant resistance is a complex trait that is...

Open AccessHigh-throughput phenoty** of plant resistance to aphids by automated video tracking
Piercing-sucking insects are major vectors of plant viruses causing significant yield losses in crops. Functional genomics of plant resistance to these insects would greatly benefit from the availability of hi...

Open AccessDevelopment of late blight resistant potatoes by cisgene stacking
Phytophthora infestans, causing late blight in potato, remains one of the most devastating pathogens in potato production and late blight resistance is a top priority in potato breeding. The introduction of multi...

A Trichome-Specific Linoleate Lipoxygenase Expressed During Pyrethrin Biosynthesis in Pyrethrum
The lipid precursor alcohols of pyrethrins—jasmolone, pyrethrolone and cinerolone—have been proposed as sharing parts of the oxylipin pathway with jasmonic acid. This implies that one of the first committed st...

Open AccessPyrethrins Protect Pyrethrum Leaves Against Attack by Western Flower Thrips, Frankliniella occidentalis
Pyrethrins are active ingredients extracted from pyrethrum flowers (Tanacetum cinerariifolium), and are the most widely used botanical insecticide. However, several thrips species are commonly found on pyrethrum ...

Open AccessMap** of the S. demissum late blight resistance gene R8 to a new locus on chromosome IX
The use of resistant varieties is an important tool in the management of late blight, which threatens potato production worldwide. Clone MaR8 from the Mastenbroek differential set has strong resistance to Phytoph...

Shoot organogenesis in leaf explants of Hydrangea macrophylla ‘Hyd1’ and assessing genetic stability of regenerants using ISSR markers
For the first time, an in vitro regeneration protocol of Hydrangea macrophylla ‘Hyd1’ was developed. Effects of different plant growth regulators (PGRs) on shoot regeneration were investigated jointly with select...

Open AccessInsect oviposition behavior affects the evolution of adaptation to Bt crops: consequences for refuge policies
The major lepidopteran insect pests of cotton and maize harbor intra-specific variation for behavior determining the selection of host plants for oviposition. Yet, the consequences of behavioral adaptation for...

Phage display of a double-headed proteinase inhibitor: Analysis of the binding domains of potato proteinase inhibitor II
Potato proteinase inhibitor II (PI2) is a serine proteinase inhibitor composed of two domains that are thought to bind independently to proteinases. To determine the activities of each domain separately, vario...

Coordinate expression of antibody subunit genes yields high levels of functional antibodies in roots of transgenic tobacco
To explore the feasibility of employing antibodies to obtain disease resistance against plant root pathogens, we have studied the expression of genes encoding antibodies in roots of transgenic plants. A model ...

Trypsin inhibitor activity in mature tobacco and tomato plants is mainly induced locally in response to insect attack, wounding and virus infection
Wounding of plants by insects is often mimicked in the laboratory by mechanical means such as cutting or crushing, and has not been compared directly with other forms of biotic stress such as virus infection. ...

Proteinase Inhibitors in Tobacco are Induced by Cutting, but Not by Crushing as in Tomato, Via a Systemin-Independent Signalling Pathway
Thus far theories dealing with the response of plants to wounding do not differentiate between different types of wounding like crushing and cutting. Upon wounding tobacco leaves, however, we found that the PI...

Endogenous proteinase inhibitors induced in tobacco in response to herbivory: effects on the interpretation of insect resistance of transgenic tobacco plants
Relatively little is known about the endogenous proteinase inhibitors induced in tobacco in response to insect herbivory, despite several reports on insect resistance based on transgenic tobacco, constitutivel...
