we find a criterion for a morphism of coalgebras over a barr-exact category to be effective descent and determine (effective) descent morphisms for coalgebras over toposes in some cases. also, we study some exactness properties of endofunctors of arbitrary categories in connection with natural transformations between them as well as those of functors that these transformations induce between co...

it is an increased interest in the therapeutic potential of cannabis sativa l. (marijuana) for treatment of multiple sclerosis and hiv neuropathy. because of limitation in cultivation of this plant, an efficient hairy root induction system for cannabis sativa l. was developed in the present study. agrobacterium rhizogenes mediated transformation performed by two different co-cultivation mediums...

This paper introduces the notion of ‘co-testability transformation’. As opposed to traditional testability transformations, which replace the original program in testing, co-testability transformations are designed to be used in conjunction with the original program (and any additional co-transformations as well). Until now, testability transformations have only been used to improve test data g...

the fungus colletotrichum gloeosporioides is the causative agent of anthracnose disease of many tropical, subtropical and temperate fruits, and a microbial source of the anticancer drug, taxol. here, we introduce an optimized agrobacterium tumefaciens-mediated transformation (atmt) protocol for genetic manipulation of this fungus using hph and gfp-tagged hph genes as selection markers. results ...

ABSTRACT- In order to produce transgenic rice lines lacking selectable marker gene, biolistic co-transformation technique using gold nanoparticles was adopted. In the first step, the efficiency of different sizes of gold particles was evaluated. The results showed that the efficiency of the nanoparticles in the transformation was comparable to that of the micro particles. Subsequently, two sepa...

Background: Oat (Avena sativa) with high nutritive value and fiber content is used as the main food grain in many countries for human diet as well as animal feed. Recently, it became difficult to transfer new genes through the conventional breeding due to the lack of desirable traits. Objectives: The current study aimed at achieving a st...
