Lesquerella fendleri seed oil contains up to 60% hydroxy fatty acids, nearly all of which is the 20-carbon hydroxy fatty acid lesquerolic acid (D-14-hydroxyeicos-cis-11-enoic acid). Previous work suggested that lesquerolic acid in L. fendleri was formed by the elongation of the 18-carbon hydroxy fatty acid, ricinoleic acid. To identify a gene encoding the enzyme involved in hydroxy fatty acid e...
The phytopathogenicity of Erwinia chrysanthemi is chiefly supported by the production of pectate lyase isoenzymes, encoded by the pel genes. One of these enzymes, PelA, encoded by the pelA gene, seems to represent only a small part of the total pectate lyase activity, but is required for full bacterial pathogenicity. To study the regulation of pelA gene expression, a pelA::uidA gene fusion was ...
With the completion of genome sequencing projects, the next challenge is to close the gap between gene annotation and gene functional assignment. Genomic tools to identify gene functions are based on the analysis of phenotypic variations between a wild type and its mutant; hence, mutant collections are a valuable resource. In this sense, T-DNA collections allow for an easy and straightforward i...
As already demonstrated in greenhouse trials, outcrossing of transgenic plants can be drastically reduced via transgene integration into the plastid. We verified this result in the field with Petunia, for which the highest paternal leakage has been observed. The variety white 115 (W115) served as recipient and Pink Wave (PW) and the transplastomic variant PW T16, encoding the uidA reporter gene...
Transcription of the Arabidopsis thaliana gene encoding ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) activase (RCA) is organ-specific, light-responsive, and regulated by the circadian clock. RCA is transcribed throughout the green parts of the plant, but not in roots and petals. Responses elicited by short pulses of light indicate that the light response is mediated, at least in pa...
GUS (uidA) reporter gene expression for two sugarcane polyubiquitin promoters, ubi4 and ubi9, was compared to expression from the maize Ubi-1 promoter in stable transgenic rice (only ubi9) and sugarcane (ubi4 and ubi9). Ubi9 drove high-level GUS expression, comparable to the maize Ubi-1 promoter, in both callus and regenerated plants of rice transformed by Agrobacterium. This high level express...
Two genomic clones (OsMET1-1, AF 462029 and OsMET1-2), each encoding a cytosine-5 DNA methyltransferase (MTase), were isolated from rice (Oryza sativa L.) BAC libraries. OsMET1-1 has an open reading frame of 4,566 nucleotides with twelve exons and eleven introns while OsMET1-2 has an open reading frame of 4,452 nucleotides with eleven exons and ten introns. Although OsMET1-1 and OsMET1-2 have h...
Phosphate (Pi) limitation causes plants to modulate the architecture of their root systems to facilitate the acquisition of Pi. Previously, we reported that the Arabidopsis (Arabidopsis thaliana) SUMO E3 ligase SIZ1 regulates root architecture remodeling in response to Pi limitation; namely, the siz1 mutations cause the inhibition of primary root (PR) elongation and the promotion of lateral roo...
when a plant is initially transformed, the transgene is present in a heterozygous form. Since white clover is outcrossing and predominantly self incompatible it is necessary to cross primary transgenic plants to produce an BC1 population, then intercross BC1 transgenic plants to produce an F2 population. The F2 population will have a highly heterogeneous genetic background and a variable alleli...
genetic transformation studies were carried out to standardize a protocol for agrobacterium -mediated genetic transformation of three economically important strawberry (fragaria x ananassa duch) cultivars kurdistan’, camarosa’, and ‘paros’. shoot regeneration frequency 72, 65 and 30% was obtained on ms (1) basal medium supplemented with 2% glucose and 4 mg/l tdz for camarosa, kurdistan and paro...
