Abstract Parasitic plants infect other by forming haustoria, specialized multicellular organs consisting of several cell types, each which has unique morphological features and physiological roles associated with parasitism. Understanding the spatial organization types is, therefore, great importance in elucidating functions haustoria. Here, we report a three-dimensional (3-D) reconstruction ha...

The plant genome evolves with rapid proliferation of LTR-type retrotransposons, which is associated with their clustered accumulation in gene-poor regions, such as centromeres. Despite their major role for plant genome evolution, no mobile LTR element with targeted integration into gene-poor regions has been identified in plants. Here, we report such targeted integrations de novo. We and others...

Self-incompatibility in Brassica species is regulated by a set of S-locus genes: SLG, SRK, and SP11/SCR. In the vicinity of the S-locus genes, several expressed genes, SLL2 and SP2/ClpP, etc., were identified in B. campestris. Arabidopsis thaliana is a self-compatible Brassica relative, and its complete genome has been sequenced. From comparison of the genomic sequences between B. campestris an...

MYB (v-MYB avian myeloblastosis viral oncogene homolog) transcription factor (TF) family has numerous members with complex and diverse functions, which perform an integral role in regulating the plant’s response to adversity. This study used cloning obtain a novel TF gene from diploid strawberry Fragaria vesca, was given designation FvMYB44. Subcellular localization results showed that protein ...

Sclerotinia sclerotiorum is a devastating plant pathogen that causes substantial losses in various agricultural crops. Although plants have developed some well-known defense mechanisms against invasive fungi, much remains to be learned about responses fungal pathogens. In this study, we investigated how S. infection affects primary and secondary metabolism the model Arabidopsis thaliana. Our re...

Biotrophic pathogens are believed to strategically manipulate sugar transport in host cells enhance their access carbohydrates. However, mechanisms of translocation from biotrophic fungi such as powdery mildew across the plant–haustorium interface remain poorly understood. To investigate this question, systematic subcellular localisation analysis was performed for all 14 members monosaccharide ...

Arabidopsis thaliana is the first plant for which the complete genome has been sequenced and published. Annotation of complex eukaryotic genomes requires more than the assignment of genetic elements to the sequence. Besides completing the list of genes, we need to discover their cellular roles, their regulation and their interactions in order to understand the workings of the whole plant. The M...

The glyoxalase pathway, which consists of the two enzymes, GLYOXALASE 1 (GLX 1) (E.C.: 4.4.1.5) and 2 (E.C.3.1.2.6), has a vital role in chemical detoxification. In Arabidopsis thaliana there are at least four different isoforms of glyoxalase 2, two of which, GLX2-1 and GLX2-4 have not been characterized in detail. Here, the functional role of Arabidopsis thaliana GLX2-1 is investigated. Glx2-1...
