Stress-induced changes in protease composition are determined by nitrogen supply in non-nodulating white clover.

An inbreeding line of white clover has been identified which remains non-nodulated under appropriate physiological conditions and so the nitrogen concentration of the plant can be manipulated by altering the nitrate supply to the roots. Non-nodulating plants were used to test the hypothesis that

Molecular cloning, functional expression in Escherichia coli and enzymatic characterisation of a cysteine protease from white clover (Trifolium repens).

This paper presents the cloning and biochemical characterisation of the cysteine protease Tr-cp 14 from white clover (Trifolium repens). The predicted amino acid sequence of Tr-cp 14 is 71%, 74% and 74% identical to the cysteine proteases XCP1 and XCP2 from Arabidopsis thaliana, and p48h-17 from

The Tr-cp 14 cysteine protease in white clover (Trifolium repens) is localized to the endoplasmic reticulum and is associated with programmed cell death during development of tracheary elements.

Cysteine proteases are known to be associated with programmed cell death, developmental senescence and some types of pathogen and stress-induced responses. In the present study, we have characterized the cysteine protease Tr-cp 14 in white clover (Trifolium repens). Tr-cp 14 belongs to the C1A

Evidence of a role for plant proteases in the degradation of herbage proteins in the rumen of grazing cattle.

Protein breakdown in the rumen is generally regarded as a two-stage process in which proteases produced by rumen microorganisms cleave plant protein into peptides and amino acids. However, many of the fiber-degrading cellulolytic species in the rumen are not in fact proteolytic, and the proteolytic

Effects of mixing red clover with alfalfa at different ratios on dynamics of proteolysis and protease activities during ensiling.

This study was conducted to study the effects of ensiled alfalfa (Medicago sativa) and red clover (Trifolium pratense) at different ratios on dynamics of fermentation parameters, N distribution, protein fractions, and protease activities during ensiling. Alfalfa and red clover were harvested and

The complete nucleotide sequence of Subterranean clover mottle virus (SCMoV) genomic RNA has been determined. The SCMoV genome is 4,258 nucleotides in length. It shares most nucleotide and amino acid sequence identity with the genome of Lucerne transient streak virus (LTSV). SCMoV RNA encodes four

Red clover (Trifolium pratense) leaves contain high levels of polyphenol oxidase (PPO) activity and o-diphenol substrates. Wounding of leaves during harvest and ensiling results in browning of leaf tissues from activity of PPO on the o-diphenols. In association with browning, leaf proteins remain

Common mycorrhizal network (CMN) allows nutrients and signals to pass between two or more plants. In this study, trifoliate orange (Poncirus trifoliata) and white clover (Trifolium repens) were planted in a two-compartmented rootbox, separated by a 37-μm nylon mesh and then inoculated with an

In mid-June 2008, distinct mosaic leaves were observed on a cluster of clover (Trifolium spp.) with light pink and white flowers growing at the edge of a lawn in Palmer, AK. Virus minipurification from leaves of affected clover and protein extractions on a polyacrylamide electrophoresis implicated a

Seeds of Dixie crimson clover (Trifolium incarnatum cv. Dixie) completed germination in 36 hours at 20 C. At 10 C germination was delayed by 24 hours. At 30 C only 20% germinated and the rest remained viable for a long time but not germinable. Different patterns of adenylate energy state and

Programmed plant cell death is a widespread phenomenon resulting in the formation of xylem vessels, dissected leaf forms, and aerenchyma. We demonstrate here that some characteristics of programmed cell death can also be observed during the cellular response to biotic and abiotic stress when plant
