Citrus fruit is prone to develop peel pitting during development and storage, which greatly decreases its fresh market value because of the deterioration of the peel. In the present study, we have examined the effect of different temperatures (15 degrees C and 4 degrees C), waxing and mechanical
The cDNAs encoding phenylalanine ammonia-lyase (PAL) and cinnamate 4-hydroxylase (C4H) were cloned from garlic (Allium sativum) using reverse transcription-polymerase chain reaction (RT-PCR) with degenerate primers and 5' and 3' rapid amplification of cDNA ends (RACE) PCR. Amino acid sequence
The cDNAs (Espals) encoding phenylalanine ammonia-lyase (PAL) were cloned from Ephedra sinica by reverse transcription polymerase chain reaction (RT-PCR) using degenerate primers and by 5' and 3'-rapid amplification of cDNA ends (RACE). 2166 bp of the open reading frame (ORF) encoded 722 amino
Phenylalanine ammonia-lyase (PAL) and cinnamate 4-hydroxylase (C4H) are important enzymes in the phenylpropanoid pathway and also in the accumulation of decursin (1) and decursinol angelate (2), which are major secondary metabolites in Angelica gigas. Using PCR with degenerate primers targeted to
Pleurotus tuoliensis is a popular edible and medical mushroom, but it is highly perishable during postharvest storage. The quality parameters, chemical composition, malondialdehyde (MDA) concentration, and activity of metabolic enzymes were studied during 12 days of storage at 4 °C and 6 days of
Phenylalanine ammonia-lyase (PAL) is the first enzyme involved in the phenylpropanoid pathway and plays important roles in the secondary metabolisms, development and defense of plants. To study the molecular function of PAL in anthocyanin synthesis of Coleus (Solenostemon scutellarioides (L.) Codd),
Using degenerate PCR primers that target evolutionarily conserved sequences in pal genes, we show that in the gymnosperm, Pinus banksiana, phenylalanine ammonia-lyase (PAL) is encoded by a multigene family of at least eight to ten loci. Five classes of pal sequence were easily distinguished among 28
Phenylalanine ammonia-lyase (PAL) is the key enzyme of the phenylpropanoid pathway, playing an important role in plant development and defence. We cloned a partial cDNA of PAL gene, DcPAL1, from Dracaena cambodiana seedlings using RT-PCR with degenerate primers that were designed based on a multiple
Phenylalanine ammonia-lyase (PAL), the first enzyme of phenylpropanoid biosynthesis, participates in the biosynthesis of flavonoids, lignins, stilbenes and many other compounds. In this study, we cloned a 2,326 bp full-length PAL2 gene from Lycoris radiata by using degenerate oligonucleotide primer
We cloned the gene, CdPAL1, from Cistanche deserticola callus using RACE PCR with degenerate primers that were designed based on a multiple sequence alignment of known PAL genes from other plant species. The gene shows high homology to other known PAL genes registered in GenBank. The recombinant
LrPAL is a novel full-length cDNA isolated from Lycoris radiata by degenerate oligonucleotide primer PCR (DOP-PCR), 3'- and 5'-RACE approaches, harbours an open reading frame (ORF) encoding a 708 amino acid product. Sequence alignment showed that the deduced amino acid sequence of LrPAL shared more
The conversion of alpha-phenylalanine to beta-phenylalanine is the first committed step in the biosynthesis of the C-13 side chain of Taxol. Thus, the novel enzyme responsible for this step, phenylalanine aminomutase (PAM), is of considerable interest for studies of Taxol biosynthesis and represents
The utilization of tungsten in traffic, smelting, mining, and other industrial applications allows its' accumulation in the environmental ecosystems. The present study included using a soluble form of tungsten (tungstate) at different levels (0, 1, 5, 10, 50, and 100 mg L-1) as a water
Sodium pheophorbide a (SPA) is a natural photosensitizer. The present study investigated the antifungal activity and mechanism of SPA against Botrytis cinerea in vitro and in vivo. Its inhibitory effect was studied on the spore germination and mycelial growth of B. cinerea. The effects of SPA on
The root-knot nematode Meloidogyne graminicola is responsible for production losses in rice ( Oryza sativa ) in Asia and Latin America. The accession TOG5681 of African rice, O. glaberrima , presents improved resistance to several biotic and abiotic factors, including nematodes. The aim of this
