Expressed sequence tags from a root-hair-enriched medicago truncatula cDNA library
The root hair is a specialized cell type involved in water and nutrient uptake in plants. In legumes the root hair is also the primary site of recognition and infection by symbiotic nitrogen-fixing Rhizobium bacteria. We have studied the root hairs of Medicago truncatula, which is emerging as an increasingly important model legume for studies of symbiotic nodulation. However, only 27 genes from...
متن کاملComparative analysis of expressed sequence tags from Malva pusilla, Sorghum bicolor, and Medicago truncatula infected with Colletotrichum species
To assess relative gene expression, expressed sequence tag redundancy was compared between EST collections from susceptible Malva pusilla and Medicago truncatula inoculated with Colletotrichum gloeosporioides f. sp. malvae and C. trifolii, respectively, and resistant and susceptible Sorghum bicolor inoculated with C. graminicola (=C. sublineolum). EST redundancies from the fungal-inoculated S. ...
متن کاملExpressed sequence tags: normalization and subtraction of cDNA libraries expressed sequence tags\ normalization and subtraction of cDNA libraries.
Expressed Sequence Tags (ESTs) provide a rapid and efficient approach for gene discovery and analysis of gene expression in eukaryotes. ESTs have also become particularly important with recent expanded efforts in complete genome sequencing of understudied, nonmodel eukaryotes such as protists and algae. For these projects, ESTs provide an invaluable source of data for gene identification and pr...
متن کاملExpressed sequence tags of Chinese cabbage flower bud cDNA.
We randomly selected and partially sequenced cDNA clones from a library of Chinese cabbage (Brassica campestris L. ssp. pekinensis) flower bud cDNAs. Out of 1216 expressed sequence tags (ESTs), 904 cDNA clones were unique or nonredundant. Five hundred eighty-eight clones (48.4%) had sequence homology to functionally defined genes at the peptide level. Only 5 clones encoded known flower-specific...
متن کاملMastoparan activates calcium spiking analogous to Nod factor-induced responses in Medicago truncatula root hair cells.
The rhizobial-derived signaling molecule Nod factor is essential for the establishment of the Medicago truncatula/Sinorhizobium meliloti symbiosis. Nod factor perception and signal transduction in the plant involve calcium spiking and lead to the induction of nodulation gene expression. It has previously been shown that the heterotrimeric G-protein agonist mastoparan can activate nodulation gen...
