The apoplast is considered the leaf compartment decisive for manganese (Mn) toxicity and tolerance in cowpea (Vigna unguiculata). Particularly apoplastic peroxidases (PODs) were proposed to be key enzymes in Mn toxicity-induced processes. The presented work focuses on the characterization of the role of hydrogen peroxide (H2O2)-producing (NADH peroxidase) and H2O2-consuming peroxidase (guaiacol...

Soybean (Glycine max L. Merr. cv. Bragg), peanut (Arachis hypogaea L. cv. Georgia Green) and rice (Oryza saliva L. cv. IR-72) were grown for a full season in sunlit, controlled-environment chambers at 350 (ambient) and 700 (double-ambient, elevated) imol CO2 moF' air, and under daytime maximum/nighttime minimum air temperature regimes ranging from 28/18 to 48/38°C for soybean and peanut, or soi...

Leaf morphology in plants is very important the evaluation of intraspecific variation. Indeed, leaves fig tree (Ficus carica L.) present a great diversity shape and size. The study consists botanical, morphological, morphometric characterization 26 local varieties cultivated different areas Bejaia (northeast Algeria). Our results indicate that morphological parameters allowed good differentiati...

During spring 2011, some fungal isolates were recovered from sterilized soil (Fig. 1, A) or vermiculite, in pots and flats in greenhouses in Shiraz University, using malt extract agar and potato dextrose agar (Fig. 1, B). Anamorphic characteristics such as conidiophores and conidia were investigated. Conidiophores 125–1350 × 7.5–15 µm, hyaline, erect, broad, septate, branched once, twice (Fig. ...

Given the economic importance of cucurbits and the losses incurred by fruit fly infestation, the population dynamics of fruit flies in cucurbit crops and the influence of abiotic parameters, such as temperature, relative humidity, rainfall, and total sunshine hours per day on the fruit fly population were studied. The study was carried out at six locations; in district Srinagar the locations we...

Vanadate (Na(3) VO(4)) inhibits leaf movement and stomatal conductance of Phaseolus vulgaris L. cv. Carlos Favorit in light-dark cycles as well as photomorphogenetic leaf unrolling of Hordeum vulgare L. cv. Rupal. Inhibition was 50% by 10 to 100 micromolar vanadate and 100% by millimolar vanadate. Leaf unrolling was also inhibited by oligomycin and diethylstilbestrol.Millimolar vanadate is requ...

conclusions addition of fc decoction to oral hypoglycemic drugs might significantly decrease 2hpp in patients with dm type 2. it is a safe and inexpensive method. the mechanism for this decrease is something other than increased insulin secretion. results thirteen patients in each group completed the trial. fbs, fructosamine, hba1c, and c-peptide baseline and post-trial amounts in the case grou...

Plants are known to have sense and can respond to touch, electric and magnetic field. The present study was designed on the sponge gourd (Luffa cylindrica) and bitter gourd (Momordica charantia) seeds with respect to biofield energy treatment. The seeds of each crop were divided into two groups, one was kept control, while the other group was subjected to Mr. Trivedi’ biofield energy treatment....

A technique for collection of phloem exudate from detached leaves using 20 millimolar EDTA (pH 7.0) has previously been developed (King, Zeevaart 1974 Plant Physiol 53: 96-103). It was the aim of the present study to determine the efficiency of this technique in relation to undisturbed export from attached leaves. Paired primary leaves of bean seedlings (Phaseolus vulgaris L. cv Montcalm) were ...

I identified a new locus responsible for increased yield potential and evaluated its physiological function to understand how to improve potential yield in rice (Oryza sativa) plants. Quantitative trait loci (QTLs) for 1,000-grain weight (TGW) were analyzed under different environments over 3 years in backcross inbred lines of rice japonica cv Nipponbare x indica cv Kasalath. Four QTLs for this...
