Abstract Nitric oxide (NO) is a highly reactive gaseous small molecule that regulates plant growth. Sodium nitroprusside (SNP) was used as an NO donor to study the effects of treatment on browning and antioxidant activity button mushrooms ( Agaricus bisporus ). The findings revealed exogenous alleviated browning, decreased hardness, increased weight loss stored at 4°C for 15 days, reduced accum...

Activation of plant defense genes was investigated by analysis of transcripts completed in vitro by isolated nuclei. Elicitor treatment of suspension-cultured bean (Phaseolus vulgaris L.) cells caused marked transient stimulation of transcription of genes encoding apoproteins of cell wall hydroxyproline-rich glycoproteins (HRGP) and the phenylpropanoid biosynthetic enzymes phenylalanine ammonia...

We developed a model system to study the signal transduction pathways leading to the activation of Arabidopsis thaliana genes involved in the defense against pathogen attack. Here we describe the identification and characterization of virulent and avirulent Pseudomonas syringae strains that elicit disease or resistance symptoms when infiltrated into Arabidopsis leaves. The virulent and avirulen...

Phenylpropanoid biosynthesis in plants engenders myriad phenolics with diverse biological functions. Phenylalanine ammonia-lyase (PAL) is the first committed enzyme in the pathway, directing primary metabolic flux into a phenylpropanoid branch. Previously, we demonstrated that the Arabidopsis (Arabidopsis thaliana) Kelch domain-containing F-box proteins, AtKFB01, AtKFB20, and AtKFB50, function ...

The phenylpropanoid pathway serves as a rich source of metabolites in plants. It is required for the biosynthesis of lignin and acts as a starting point for the production of many other important compounds involved in growth and development. Phenylalanine ammonia-lyase (PAL) catalyzes the first step of the phenylpropanoid pathway. PAL gene expression changes during the growth and development of...

Penyakit layu bakteri yang disebabkan oleh Ralstonia solanacearum merupakan salah satu penyakit penting pada tanaman eukaliptus (Eucalyptus pellita) di Indonesia. Salah pendekatan teknik pengendalian adalah melalui pemanfaatan endofit dan fungi mikoriza arbuskula (FMA). Penelitian ini ditujukan untuk mengevaluasi keefektifan FMA dalam menekan perkembangan bakteri. Terdapat sepuluh kombinasi di-...

Biocontrol agents are an environmentally friendly alternative to chemical pesticides against phytopathogens. The effectiveness of metabolites produced by Bacillus atrophaeus B5 for controlling anthracnose Colletotrichum gloeosporioides in harvested fruit and the possible action mechanisms have been studied. Avocado treated with reduced 54% incidence nearly 70% lesion than untreated fruit. treat...

Compounds with planar triple ring systems such as acridine orange, 9-amino acridine, 9-amino-1,2,3, 4-tetrahydroacridine (tacrine), 6,9-diamino-2-ethoxyacridine lactate monohydrate (DE-acridine), 6-chloro-9-(3'-diethylamino-2'-hydroxypropylamino)-2-methoxyacridine 2 HCI (CDM-acridine), quinacrine, 6-chloro-9(4'diethylamino1'-methylbutylamino) .2-methoxy. 1, 10-diazaanthracene (CDM 1, 10-diazaan...

This work evaluated the effect of drought stress on seedling growth, protein, soluble sugars, and phenolic compounds of two cultivars of canola (RGS003 and Sarigol). Drought stress was induced with polyethylene glycol (PEG) at 0, 5, 10, and 15%. Drought stress increased root fresh weight in both cultivars and the effect of drought was more pronounced in RGS003. Shoot fresh weight reduced in Sar...
