The plant elicitors use as an agricultural input is limited and few studies show their influence on physiological responses. However, its can induce broad-spectrum long-lasting resistance in plants by inducing defense systems, primary secondary metabolism. the aim of this study was to evaluate gas exchange (gs, A, E, Ci, WUE, iWUE iCE) enzymatic antioxidant system (POD, PPO PAL) Z. mays under a...
This research was conducted to study the effect of nematode (Meloidogyne javanica) on severity of tomato Fusarium wilt (Fusarium oxysporum f.sp. lycopersici race 1) and changes in Phenylalanine ammonia lyase (PAL) activity in split-root assays to show the possibility of systemic induced susceptibility caused by nematode to the fungus by local nematode infection. The results showed that the acti...
Immobilized metal ion affinity chromatography principles were applied for selective immobilization of recombinant polyhistidine tag fused phenylalanine ammonia-lyase from parsley (PcPAL) on porous polymeric support with aminoalkyl moieties modified an EDTA dianhydride (EDTADa)-derived chelator and charged transition ions. Out the five investigated ions - Fe3+, Co2+, Ni2+, Cu2+, Zn2+ best biocat...
Phenylalanine ammonia-lyase (PAL) is the first enzyme in phenylpropanoid pathway and plays a vital role adoption, growth, development plants but wheat its characterization still not very clear. Here, we report genome-wide identification of TaPAL genes analysis their transcriptional expression, duplication, phylogeny wheat. A total 37 that cluster into three subfamilies have been identified base...
As it was previously reported, black spot development in the skin of Hass avocado has been related to a decreased antioxidant defense system. The aim this study investigate effect different postharvest storage conditions on controlling targeting their system (non-enzymatic and enzymatic) skin. Four treatments (T1: regular air (RA) at 5 °C for 40 d; T2: controlled atmosphere (CA) 4 kPa O2 6 CO2 ...
Flavonols, phenylalanine-derived secondary metabolites, have protective and regulatory functions in plants. In Arabidopsis thaliana, they are consecutively glycosylated at their 3-OH and 7-OH groups. UGT78D1 and UGT78D2 are the major flavonol 3-O-glycosyltransferases in Arabidopsis leaves. The ugt78d1 ugt78d2 double mutant, which was strongly compromised in the initial 3-O-glycosylation, showed...
The phenylpropanoid pathway in plants synthesizes a variety of structural and defence compounds, and is an important target in efforts to reduce cell wall lignin for improved biomass conversion to biofuels. Little is known concerning the trade-offs in grasses when perturbing the function of the first gene family in the pathway, PHENYLALANINE AMMONIA LYASE (PAL). Therefore, PAL isoforms in the m...
A split plot factorial 2 × 3 experiment was designed to examine and characterize the relationships among secondary metabolites (total phenolics, TP; total flavonoids, TF), carbohydrate content, C/N ratio, protein synthesis and L–phenylalanine ammonia lyase (PAL; EC 4.3.1.5) activity in the Malaysian medicinal herb Labisia pumila (Blume) FernVill. under different CO2 concentrations (400 = ambien...
Photorhabdus is a genus of Gram-negative bacteria from the family Enterobacteriaceae. Members of Photorhabdus have a complex life cycle during which the bacterium has a pathogenic interaction with insect larvae whilst also maintaining a mutualistic relationship with nematodes from the family Heterorhabditidae. During growth in the insect, Photorhabdus bacteria produce a broad-spectrum antibioti...
