Proteomic analysis of 'hybrid necrosis' in wheat (Triticum aestivum) leaves

Numai utilizatorii înregistrați pot traduce articole

Wheat hybrid necrosis has been genetically characterised for many years, but the specific gene(s) and the protein products involved in the processes remains unknown. In this study, protein expression in the base (B), mid (M) and tip (T) segments of the FL-2 leaves of a necrotic hybrid, PZF1 and its

Phytotoxins from the leaves of Laggera decurrens.

Numai utilizatorii înregistrați pot traduce articole

Upon biological screening of a series of African medicinal plants, substantial phytotoxic activity was found in the leaves of Laggera decurrens (Vahl.) Hepper & Wood (Asteraceae), using a Lemna minor bioassay. Bioassay-guided fractionation of the leaves led to the isolation of two physiologically

Leaves of symptomless Fragaria ananassa Duch cv. Cacanská raná were grafted onto Fragaria vesca indicator clones. Thirty-five of 72 grafted indicator plants developed leaf mottle symptoms. Isometric virus-like particles were observed in purified preparations from symptomatic leaves of F. vesca. The

Resistance to tobacco necrosis virus induced by salicylate in detached tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

Sodium salicylate reduced both the size and viral antigen content of non-self-limiting necrotic lesions produced by tobacco necrosis virus (TNV) in detached tobacco leaves during the partly localized reaction to virus. The antiviral effect of salicylate occurred at concentrations close to the limits

Numai utilizatorii înregistrați pot traduce articole

Eugenia dysenterica ex DC Mart. (Myrtaceae), popularly known as "cagaita," is a Brazilian plant rich in polyphenols and other antioxidant compounds. Aiming to evaluate the potential use of cagaita in pathologies involving oxidative stress, such as neurodegenerative disorders, this study investigated

Chloroplast DNA in mature and senescing leaves: a reappraisal.

Numai utilizatorii înregistrați pot traduce articole

The fate of plastid DNA (ptDNA) during leaf development has become a matter of contention. Reports on little change in ptDNA copy number per cell contrast with claims of complete or nearly complete DNA loss already in mature leaves. We employed high-resolution fluorescence microscopy, transmission

Trypanocidal activity of polysaccharide extract from Genipa americana leaves.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The parts of the Genipa americana (Rubiaceae) tree, also known as "jenipapo" or "jenipapeiro", has been used in traditional Medicine in parasitic and bacterial infections. Thus, the experimental evolution of the antiparasitic activity of polysaccharide extracts from Genipa americana

"Falling leaves": a survey of the history of apoptosis.

Numai utilizatorii înregistrați pot traduce articole

Cell death has long been defined using morphological criteria. A first important concept, "necrosis", was early identified by Areteo from Cappadocia and by Galen. The term apoptosis was introduced by Kerr in 1972 to indicate a particular form of death in which cells commit suicide by chopping

Colletotrichum dematium Produces Phytotoxins in Anthracnose Lesions of Mulberry Leaves.

Numai utilizatorii înregistrați pot traduce articole

ABSTRACT Colletotrichum dematium, the causal agent of mulberry anthracnose, was examined to produce phytotoxins in vitro and in planta. Raw and autoclaved mulberry leaves infected with the fungus, as well as the fungus incubated with several solid or liquid media, were extracted with acetone.

Chloride localization in Phaseolus vulgaris leaves exposed to HCl gas.

Numai utilizatorii înregistrați pot traduce articole

An investigation of chloride accumulation and distribution in unifoliate leaves of Phaseolus vulgaris following supra-acute exposures to gaseous hydrogen chloride (HCl) was conducted. Plants which were 8-22 days old (post-seeding) were exposed for 20 min to HCl gas in concentrations ranging from

Phomalactone from a Phytopathogenic Fungus Infecting ZINNIA elegans (ASTERACEAE) Leaves.

Numai utilizatorii înregistrați pot traduce articole

Zinnia elegans Jacq. plants are infected by a fungus that causes dark red spots with necrosis on leaves, particularly in late spring to the middle of summer in the Mid-South of the United States. This fungal disease causes the leaves to wilt and eventually kills the plant. The fungus was isolated,

Characteristics of ethylene biosynthesis-inducing xylanase movement in tobacco leaves.

Numai utilizatorii înregistrați pot traduce articole

(125)I-Labeled ethylene biosynthesis-inducing xylanase (EIX) was used to study the movement of this protein in tobacco (Nicotiana tabacum) tissues. A biologically active (125)I-labeled EIX was obtained using chloramine-T as the oxidizing agent. Labeled EIX was detected in the far most edges of the

Evaluation of the Wound Healing Properties of Hancornia speciosa Leaves.

Numai utilizatorii înregistrați pot traduce articole

The leaves of Hancornia speciosa Gomes (Apocynaceae), a medicinal species found in the Brazilian cerrado biome, are traditionally used to treat wounds and inflammatory disorders. The goal of the present study was to investigate the in vitro wound healing properties of ethanolic extract of H.

Antimicrobial activity of Willowherb (Epilobium angustifolium L.) leaves and flowers.

Numai utilizatorii înregistrați pot traduce articole

Since the aetiology of benign prostatic hyperplasia (BHP) is still unknown, the use of medicinal herb extracts and products prepared thereof are recommended due to their antimicrobial activity, especially during early stages of BHP. A comparison was performed of the in vitro antimicrobial activity
