  AtDGAT3 is highly and ubiquitously expressed in A. thaliana and could therefore fulfill housekeeping function(s), such as the regulation of acyl exchanges between TAGs . A detailed analysis of the currently available Arabidopsis thaliana genomic sequence has revealed the presence of a large number of open reading frames with homology to the stigmatic self-incompatibility (S) genes of Papaver rhoeas. The products of these potential genes are all predicted to be relatively small, basic, secreted proteins with similar predicted secondary structures.

To understand how the direction of root growth changes in response to obstacles, light, and gravity, we characterized an Arabidopsis thaliana mutant, wavy growth 2 (wav2), whose roots show a short-pitch pattern of wavy growth on inclined agar medium. The roots of the wav2 mutant bent with larger curvature than those of the wild-type seedlings in wavy growth and in gravitropic and phototropic. One of them is the DNA mismatch repair (MMR) pathway. The main part of the MMR is the MutS homologue (MSH) protein family. The genome of Arabidopsis thaliana encodes at least seven homologues of the MSH family: AtMSH1, AtMSH2, AtMSH3, AtMSH4, AtMSH5, AtMSH6, and AtMSH7.

  Arabidopsis thaliana Columbia (Col) ecotype was obtained from the Arabidopsis Biological Resource Center. The plants were grown in growth chambers at 22 °C under μmol m - 2 s - 1 light with a h light/h dark photoperiod [ 42 ]. An Arabidopsis thaliana cDNA clone, AtTPS1, that encodes a trehalose‐6‐phosphate synthase was identity of this protein is supported by both structural and functional evidence. On one hand, the predicted sequence of the protein encoded by AtTPS1 showed a high degree of similarity with trehalose‐6‐phosphate synthases of different organisms.

Molecular analysis of AtALY1, AtALY2 and AtALY3Cited by:   The expression of systemic acquired resistance (SAR) in plants involves the upregulation of many Pathogenesis-Related (PR) genes, which work in concert to confer resistance to a broad spectrum of pathogens.

Because SAR is a costly process, SAR-associated transcription must be tightly regulated.

Analysis of Arabidopsis thaliana genomic sequence revealed the presence of two genes encoding putative homologues of cyanobacterial RbcX protein: AtRbcX1 (At4G) and AtRbcX2 (At5G).

Abstract. Six new Arabidopsis thaliana genes (AtRCI2C-H) have been identified that show high homology to AtRCI2A and ce comparisons revealed that AtRCI2-related genes are widely spread among very different organisms, including other plant species, prokaryotes, fungi, and simply organized animals, and are also organized in gene families.

Most RCI2 genes show a similar. Arabidopsis (rockcress) is a genus in the family are small flowering plants related to cabbage and genus is of great interest since it contains thale cress (Arabidopsis thaliana), one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced.

Changes in thale cress are easily observed, making it a very useful. Arabidopsis thaliana is a small member of the mustard family, botanical information on which dates back to the 16th century. It has many advantages as a model system for plant molecular genetics. Recent studies of meiotic recombination in the budding yeast and the model plant Arabidopsis thaliana indicate that meiotic crossovers (COs) occur through two genetic pathways: the interference-sensitive pathway and the interference-insensitive pathway.

However, few genes have been identified in either pathway. Here, we describe the identification of the PARTING DANCERS (PTD) gene, as a gene. We searched the P. patens genome sequence for auxin biosynthesis genes and found homologues of six Arabidopsis thaliana (At) YUCCA (AtYUC) (Gallavotti et al., ; Rensing et al., ) and four AtTAA1 genes, which encode enzymes proposed to act in two separate tryptophan-dependent pathways (Stepanova et al., ; Tao et al., ; Zhao et al.
