The European water frog Rana esculenta (RL), a natural hybrid between R. ridibunda (RR) and R. lessonae (LL), reproduces by hybridogenesis: haploid gametes usually contain an intact chromosome set of R. ridibunda (R); the lessonae nuclear genome (L) is lost from the germ line. Hybridity is restored in the next generation, via fertilization by syntopic R. lessonae. Matings between two hybrids (R...

We selected seven wild Basidiomycota and Ascomycota mushrooms to evaluate their antibacterial activity: Cyclocybe aegerita, Cortinarius traganus, Gyroporus castaneus, Neoboletus luridiformis, Rubroboletus lupinus, Gyromitra esculenta, Helvella crispa. Four mushrooms, three of which have not been tested date, displayed potential, with a minimal inhibition concentration (MIC) ≤ 125 μg/mL against ...

BACKGROUND Over exploitation of many traditional medicinal plants like Myrica esculenta has become a threat and in the near future, many medicinal plants may be unavailable for use of industry. OBJECTIVE Present study outlines the concept of plant part substitution. Stem bark and small branches of M. esculenta are compared on the basis of physicochemical analysis, phytochemical analysis, tota...

Background: Many short peptides have proved to exhibit potential anti-hypertensive activity through the inhibition of the Angiotensin I-converting enzyme (ACE) activity and the regulation of blood pressure. However, the traditional experimental screening method for ACE inhibitory peptides is time consuming and costly, accompanied with the limitations as incomplete hydrolysis and peptides loss d...

Phylogenetic relationships among Chinese species of Morella (Myricaceae) are unresolved. Here, we use restriction site-associated DNA sequencing (RAD-seq) to identify candidate loci that will help in determining phylogenetic relationships among Morella rubra, M. adenophora, M. nana and M. esculenta. Three methods for inferring phylogeny, maximum parsimony (MP), maximum likelihood (ML) and Bayes...

cis-3-Amino-l-proline, identified once as a nonprotein amino acid from the fruiting bodies of Morchella esculenta Fr., was isolated also from the growth medium and cultured mycelia of the same fungus.

an investigation was carried out to reveal the changes in the concentration of soluble carbohydrates under tuber dormancy in food yam (dioscorea esculenta) tubers and in an economically important spice cum medicinal plant turmeric (curcuma longa) rhizomes under storage. harvested, fully matured tubers of yam and rhizomes of turmeric were stored in wooden boxes under the conditions of 28 ? 2?c t...

Background: In Nigeria, the leaves of Manihot esculenta (Crantz) are eaten as vegetables. The leaves are rich in phytochemicals, valuable and natural sources of antioxidants, and are highly useful for human health and disease prevention. This study was aimed to evaluate the in vitro inhibitory effects of two extracts derived from the plant leaves on α-glucosidase and α-amylase. The total flavon...

Soluble starch synthase I (SSSI) cDNA was isolated from taro (Colocasia esculenta var. esculenta) by RT-PCR and rapid amplification of cDNA ends reaction. The transcript of this single-copy gene is 2340 bp and encodes 642 amino acids protein containing a putative transit peptide of 54 residues. Recombinant SSSI protein displayed both primer-dependent and primer-independent activities of starch ...

The main objectives of this study wre to asses the effect of Triadimefon and Hexaconazole on the non-enzymatic antioxidant potentials of Manihot esculenta Crantz during the growth and maturation period. One litre of 20 mg L triadimefon and 15mg L hexaconazole solution per plant was used for the treatment -1 -1 and control was treated with one litre of irrigation water. The treatment was given o...
