Phenylalanine ammonia-lyase (PAL) is the first key enzyme of the phenypropanoid pathway. A full-length cDNA of PAL gene was isolated from Juglans regia for the first time, and designated as JrPAL. The full-length cDNA of the JrPAL gene contained a 1935bp open reading frame encoding a 645-amino-acid protein with a calculated molecular weight of about 70.4 kD and isoelectric point (pI) of 6.7. Th...

The purpose of this study was to evaluate the role of 638-nm and 665-nm LEDs on changes of antioxidants of basil (Ocimum basilicum) and parsley (Petroselinum crispum), and to assess the effect of light quality on antioxidative status. Plants were grown in peat substrate for 19 days (21/17 ±2°C, 16 h). Experiments were performed in (I) a controlled-environment: B455,R638,R665,FR731(control); B45...

The levels of four different heavy metals [cadmium (Cd), lead (Pb), chromium (Cr) and copper (Cu)] were determined in various vegetables [leek (Allium ampeloprasum), sweet basil (Ocimum basilicum), parsley (Petroselinum crispum), garden cress (Lepidium sativum) and tarragon (Artemisia dracunculus)] cultivated around Sanandaj City. The contributions of the vegetables to the daily intake of heavy...

Herbs are extensively consumed in the United Arab Emirates for their flavoring and medicinal properties. This study aimed at determining the concentration of heavy metals in selected traditional herbs consumed in the United Arab Emirates (UAE). A total of 81 samples of seven herbs, parsley (Petroselinum crispum), basil (Ocimum basilicum), sage (Salvia officinalis), oregano (Origanum vulgare), m...

Parsley (Petroselinum crispum) cell cultures respond rapidly to treatment with fungal elicitor by the accumulation of coumarin phytoalexins in the culture fluid and by incorporation of ferulic esters into their cell walls. S-Adenosyl-l-methionine:trans-caffeoyl-CoA 3-O-methyltransferase activity, specifically involved in the formation of ferulic esters, is induced under these conditions. Such a...

WRKY transcription factors form a large family that plays a role in plant responses to biotic stress and during senescence. Defining in vivo relevant WRKY/promoter relationships has been hampered by the factors’ indiscriminate binding to known W box DNA elements and their possible genetic redundance. Employing chromatin immunoprecipitations (ChIP) of cultured cells, we show that parsley (Petros...
