Endoreduplication is a specialized cell cycle in which DNA replication occurs, but mitosis is skipped creating enlarged polyploid cells. Endoreduplication is associated with the differentiation of many specialized cell types. In the Arabidopsis thaliana sepal epidermis endoreduplicated giant cells form interspersed between smaller cells. Both the transcription factor Arabidopsis thaliana MERIST...

in mulberry orchards in northern part of iran, thrips is a dominant pest and causing a lot of damage to the mulberry. the effect of pest on bio-chemical parameters of mulberry leaf of two varieties viz. kenmochi and ichenoise and also the effect of feeding of infested leaves on rearing performances have been studied. for the study, six plots of 200 m2 area of both the varieties were selected an...

To find the protective role of exogenous nitric oxide (NO) on salinity-stressed rice seedlings, a CRD-based factorial experiment with three replications was conducted in Agronomy Laboratory of the Faculty of Agricultural Sciences, University of Guilan, in 2012. The experimental design consisted of healthy and vigorous seedlings of two rice cultivars, Khazar and Goohar, the last already known as...

introduction roselle (hibiscus sabdariffa l.) as a medicinal plant belongs to the malvacea family. their active ingredient increases under water stress. humic acid bacteria derived from humus and other natural resources have hormonal effects and can improve nutrient absorption to enhance performance especially under stress conditions . materials and methods this experiment was conducted in the ...

Three cannulated Tswana steers were used to investigate the rumen degradability of mopane worm (Imbrasia belina) by measuring the amount of dry matter (DM) and crude protein (CP) disappearing at incubation periods up to 72 h. The effective degradability (ED) of DM and CP in the rumen was calculated at outflow rates of 0.03 / h (ED0.03) and 0.05 / h(ED0.05). Rumen degradable CP (RDP) was estimat...

The aim of investigation was to determine the effects of aspect (north and south) on some morphological [plant height (cm), number of stems per plant, main stem diameter (mm), number of leaves per main stem, petiole length (cm), leaflet length (cm), leaflet width (cm), leaf: stem ratio] and chemical [crude protein (%), crude cellulose (%), calcium (%), phosphorus (%), potassium (%) and magnesiu...

Pathogenesis-related protein-la (PR-la) is a protein of unknown function that is strongly induced during the onset of systemic acquired resistance (SAR) in tobacco. The expression of PR-la is under complex regulation that is controlled at least partially by the rate of transcription. In this study, we demonstrated that 661 bp of 5’flanking DNA was sufficient to impart tobacco mosaic virus and s...

The aim of this study was to determine the chemical composition and in vitro digestibility, and to estimate the in vitro fermentation parameters of palm leaves and pedicels from Ghars palm variety. A rumen in situ technique was also used to examine In vitro Digestible Dry Matter (IDDM), In vitro Digestible Crude Protein (IDCP), and In vitro Digestible Neutral Fiber (IDNF), and rate and extent o...
