The objective of this review paper is to summarize on the history, advantages, disadvantages in vitro micropropagation strawberry crop. Since traditional method propagation, that is, use runners as propagating material, not efficient because it leads spread viral diseases. We have go for micropropagation, crops also yield more when compared methods propagation. reviews a study done develop prot...

This investigation was carried out at the Tissue Culture Lab., Biotechnology Research Center (BTRC) in Tripoli, Libya 2009 to establish a micro propagation protocol for two hybrids of Tomato which several factors were studied including effect concentration growth regulator on shoot multiplication, and rooting explant MS media. Shoot tips cultured into (MS medium) with different concentrations b...

Despite the growing knowledge concerning allelopathic interference with barnyard grass, little is understood regarding competitive physiological mechanisms of interaction between rice and herbicide-resistant grass. A hydroponic system was employed to investigate root morphological traits different phytohormonal changes in non-allelopathic cultivars when co-planted quinclorac-resistant -suscepti...

While moving through their environment, medicinal leeches stop periodically and wave their head or body back and forth. This activity has been previously described as two separate behaviors: one called 'head movement' and another called 'body waving'. Here, we report that these behaviors exist on a continuum, and provide a detailed description of what we now call 'scanning'. Scanning-related be...

Sex differentiation of flower buds is an important developmental process that directly affects fruit yield of cucumber (Cucumis sativus L.). Plant hormones, such as gibberellins (GAs) and ethylene can promote development of male and female flowers, respectively, however, the regulatory mechanisms of GA-induced male flower formation and potential involvement of ethylene in this process still rem...

Potato Homeobox 15 (POTH15) is a KNOX-I (Knotted1-like homeobox) family gene in potato that is orthologous to Shoot Meristemless (STM) in Arabidopsis. Despite numerous reports on KNOX genes from different species, studies in potato are limited. Here, we describe photoperiodic regulation of POTH15, its overexpression phenotype, and identification of its potential targets in potato (Solanum tuber...

UNLABELLED Tetraploidy modifies root anatomy which may lead to differentiated capacity to uptake and transport mineral elements. This work provides insights into physiological and molecular characters involved in boron (B) toxicity responses in diploid (2x) and tetraploid (4x) plants of Carrizo citrange (Citrus sinensis L. Osb. × Poncirus trifoliata L. Raf.), a widely used citrus rootstock. Wit...

The enzyme catechol oxidase plays a key role in the manufacture of black tea. It is responsible for most, if not for all, of the chemical reactions which take place during tea fermentation. For this reason much research has been, and con tinues to be, devoted to the elucidation of the properties of this enzyme. Until recently, it was generally believed that the enzyme was insoluble in nature an...
