Oxidative injury of the root elongation zone is a primary event in aluminum (Al) toxicity in plants, but the injuring species remain unidentified. We verified the hypothesis that lipid peroxide-derived aldehydes, especially highly electrophilic alpha,beta-unsaturated aldehydes (2-alkenals), participate in Al toxicity. Transgenic tobacco (Nicotiana tabacum) overexpressing Arabidopsis (Arabidopsi...

The Ras oncoprotein must be modified by farnesyl transferase (FTase) for biological activity. Therefore, inhibition of FTase may offer a means to block ras induced cell transformation. To address this hypothesis, we have introduced antisense and dominant inhibitory FTase expression plasmids into a panel of normal, mutant ras-, and mos- transformed rodent fibroblasts in an effort to genetically ...

Primitive root is a fundamental concept in modern cryptography as well as in modern number theory. Fermat prime numbers have practical uses in several branches of number theory. As of today, there is no simple general way to compute the primitive roots of a given prime, though there exists methods to find a primitive root that are faster than simply trying every possible number. We prove the eq...

Elite genotypes from high yielding variety of Artemisia annua L. (Jeevanraksha, CIMAP Lucknow) were regenerated form nodal explants and maintained in MS culture medium with BAP and NAA. The leaves of tissue culture grown plants were inoculated with Agrobacterium rhizogenes strain LBA9402 containing the selective marker gene NPT II. Hairy roots emerged from the leaves, 8-10 days after inoculatio...

Phelipanche aegyptiaca is an obligate holoparasite that causes serious negative effects on crop growth and productivity, effective control of which difficult due to its unique biological characteristics. In this study, we performed a comparative transcriptome analysis resistant susceptible Cucumis melo cultivars (KR1326 K1237) inoculated with P. aegyptiaca. CmNLR (encodes TIR-type NLR protein, ...

Purpose: The objective of this study was to investigate the physicochemical characteristics seeds oil extracted, roots and leafs from genetically modified cotton local non-genetically modified.
 Methodology: Cotton samples were collected Elguziera State farms White Nile farms, Sudan. Collected transferred Central research laboratory natural environmental resources. Oil extracted using soxh...

background and objectives: hyoscyamus reticulatus contains two distinguished tropane alkaloids, hyoscyamineand scopolamine and both of the compounds possesspotential acute or chronic toxicity. in the present study, a simple and efficient transformation system was established for in vitro hairy roots induction in hyoscyamus reticulatus. methods: effect of different factors including agrobacteriu...

Sugar metabolism and the oxidative pentose phosphate pathway (OPPP) are strongly implicated in N assimilation, although the relationship between them and the roles of the plastidial and cytosolic OPPP have not been established genetically. We studied a knock-down mutant of the plastid-localized OPPP enzyme 6-phosphogluconolactonase 3 (PGL3). pgl3-1 plants exhibited relatively greater resource a...

The present study deals with the establishment of rolA-transgenic and rolB-transgenic plants for first time through Agrobacterium tumefaciens mediated transformation, exploiting inherent morphogenic potential an important medicinal plant, Bacopa monnieri (L.) Wettst. showed integration expression rolA rolB genes respectively, whereas Ri-transformed rolA, rolB, rolC rolD genes. Morphogenic diffe...
