14 Selectable Marker Genes: Types and Interactions

Abdeen, Ashraf (John Wiley & Sons, 2011-01-31)

The uptake of transgenic technologies for basic research and commercialization has been rapid and extensive. Yet, only a few studies have been published on the impacts of transgenesis on fundamental genetic processes or ...
Conserved MYC transcription factors play a key role in jasmonate signaling both in tomato and Arabidopsis

Abdeen, Ashraf; Abdeen, Ashraf (Cold Spring Harbor Lab, 2004-07-01)

Jasmonates (JA) are important regulators of plant defense responses that activate expression of many wound-induced genes including the tomato proteinase inhibitor II (pin2) and leucine aminopeptidase (LAP) genes. Elements ...
Control of somatic embryogenesis and embryo development by AP2 transcription factors

Abdeen, Ashraf (Springer Netherlands, 2010-11-01)

Members of the AP2 family of transcription factors, such as BABY BOOM (BBM), play important roles in cell proliferation and embryogenesis in Arabidopsis thaliana (AtBBM) and Brassica napus (BnBBM) but how this occurs is ...
GALACTURONOSYLTRANSFERASE-LIKE5 is involved in the production of Arabidopsis seed coat mucilage

Abdeen, Ashraf (American Society of Plant Biologists, 2013-11-01)

The function of a putative galacturonosyltransferase from Arabidopsis (Arabidopsis thaliana; At1g02720; GALACTURONOSYLTRANSFERASE-LIKE5 [AtGATL5]) was studied using a combination of molecular genetic, chemical, and ...
Identification and analysis of an outer-seed-coat-specific promoter from Arabidopsis thaliana

Abdeen, Ashraf (Springer Netherlands, 2013-03-01)

Differentiation of the Arabidopsis thaliana ( Arabidopsis) seed coat epidermal cells involves pronounced changes highlighted by the synthesis and secretion of copious amounts of dispensable, pectinaceous mucilage followed ...
In vitro selection and identification of drought-tolerant mutants in sweet potato.

Abdeen, Ashraf (orgz, 2010-01-01)

Abiotic stresses have become an integral part of crop production. One or other persist either in soil or in atmosphere. With the ultimate goal to raise the crop plants with better suitability towards rapidly changing ...
Multiple insect resistance in transgenic tomato plants over-expressing two families of plant proteinase inhibitors

Abdeen, Ashraf (Kluwer Academic Publishers, 2005-05-01)

Protease inhibitors have been proposed as potential defense molecules for increased insect resistance in crop plants. Compensatory over-production of insensitive proteases in the insect, however, has limited suitability of ...
The pleiotropic effects of the bar gene and glufosinate on the Arabidopsis transcriptome

Abdeen, Ashraf (Blackwell Publishing Ltd, 2009-04-01)

The Arabidopsis transcriptome was studied using the Affymetrix Arabidopsis ATH1 GeneChip in wild-type plants and glufosinate-tolerant transgenic plants expressing the bialaphos resistance (bar) gene. Pleiotropic effects ...
Selectable marker genes and unintended changes to the plant transcriptome

Abdeen, Ashraf (Blackwell Publishing Ltd, 2009-04-01)

The intended effect of a selectable marker gene is to confer a novel trait that allows for the selection and recovery of transgenic plants. Unintended effects may also occur as a result of interactions between the selectable ...
Transcriptome analysis reveals absence of unintended effects in drought-tolerant transgenic plants overexpressing the transcription factor ABF3

Abdeen, Ashraf (BioMed Central, 2010-12-01)

Background: Plants engineered for abiotic stress tolerance may soon be commercialized. The engineering of these plants typically involves the manipulation of complex multigene networks and may therefore have a greater potential ...
