Cell Separation Processes in Plants—Models, Mechanisms and Manipulation
TLDR
The use of transgenic plants and model systems such as Arabidopsis is assisting the understanding of the mechanisms that regulate abscission and dehiscence and the application of this information will advance understanding of cell separation processes in general. Expand
Effects of the soybean (Kunitz) trypsin inhibitor on growth and digestive proteases of larvae of Spodoptera litura
TLDR
Titration, in vitro of the soybean (Kunitz) trypsin inhibitor (SBTI) against each enzyme at its optimal pH revealed that the inhibitor was most effective at retarding the trypsIn-like activity, only slightly effective against the elastase-like and chymotrypsin esterase- like activity, but completely ineffective against leucine aminopeptidase.

Complex formation between recombinant ATP sulfurylase and APS reductase of Allium cepa (L.)
Recombinant ATP sulfurylase (AcATPS1) and adenosine‐5′‐phosphosulfate reductase (AcAPR1) from Allium cepa have been used to determine if these enzymes form protein–protein complexes in vitro. Using aExpand
Observations on the leaf anatomy of Festuca novae‐zelandiae and biochemical responses to a water deficit
Abstract An examination using scanning electron microscopy, of the leaf anatomy of the New Zealand native tussock grass Festuca novae‐zelandiae, has been undertaken to highlight adaptationsExpand
Accumulation of a chymotrypsin inhibitor in transgenic tobacco can affect the growth of insect pests
TLDR
It is concluded that for certain insects the use of chymotrypsin inhibitors should now be evaluated as an effective strategy to provide field resistance against insect pests in transgenic plants, but further, that a single proteinase inhibitor gene may not be universally effective against a range of insect pests. Expand
Changes in photosynthetic efficiency and carotenoid composition in leaves of white clover at different developmental stages
TLDR
The role of the xanthophylls cycle in the protection of PSII during leaf senescence is discussed in terms of the role of a constant ratio between the two pigments and the relative abundance of carotenoids altered during leaf ontogeny. Expand
Characterization of the 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase multigene family of Malus domestica Borkh.
TLDR
Gene expression analysis has shown that MD-ACO1 is restricted to fruit tissues, with optimal expression in ripening fruit, MD-acO2 expression occurs more predominantly in younger fruit tissue, with some expression in young leaf tissue, while MD- ACO3 is expressed predominantly in young and mature leaf tissue. Expand
Ethylene and carbon dioxide production by developing strawberries show a correlative pattern that is indicative of ripening climacteric fruit
TLDR
Laser photoacoustic spectroscopy continuously quantified the ethylene (C2H4) produced by strawberry flowers and fruits developing in planta and dissected fruit partsExogenous application of silver thiosulphate (STS) to detached flowers inhibited petal abscission and flower senescence and established that C1H4 production is regulated by negative feedback until fruits had expanded. Expand
Expression of 1-aminocyclopropane-1-carboxylate oxidase during leaf ontogeny in white clover.
TLDR
Three distinct 1-aminocyclopropane-1-carboxylic acid oxidase genes are examined during leaf ontogeny in white clover (Trifolium repens), revealing that TRACO1 is expressed specifically in the apex and TRO2 is expressed in the Apex and in developing and mature green leaves, with maximum expression in developing leaf tissue. Expand
Neotyphodium fungal endophytes confer physiological protection to perennial ryegrass (Lolium perenne L.) subjected to a water deficit
TLDR
It is demonstrated that N. lolii can confer protection to perennial ryegrass from water stress and that levels of the bioprotective metabolites, lolitrem B and ergovaline were altered in response to this abiotic stress in a manner that was specific for each symbiotic association. Expand
