Novel expression patterns of phosphatidylinositol 3-hydroxy kinase in nodulated Medicago spp. plants.
نویسندگان
چکیده
A cDNA clone encoding a phosphatidylinositol 3-kinase (PtdIns 3-kinase) has been characterized from Medicago truncatula, Mtpi3k, that is highly homologous to their counterparts from soybean (over 84%). The results suggest the presence of at least two genes coding PtdIns 3-kinases in M. truncatula. Mtpi3k transcript levels increased in nodules, compared with non-infected roots. Strikingly, Mtpi3k mRNA accumulated in young elongating stems at higher levels than that observed in other organs. Enhanced transcription of genes coding PtdIns 3-kinases might occur in tissues experiencing a high degree of vesicle trafficking and cell elongation.

Improved Drought Stress Response in Alfalfa Plants Nodulated by an IAA Over-producing Rhizobium Strain
The drought-stress response in plant involves the cross-talk between abscisic acid (ABA) and other phytohormones, such as jasmonates and ethylene. The auxin indole-3-acetic acid (IAA) plays an integral part in plant adaptation to drought stress. Investigation was made to see how the main auxin IAA interacted with other plant hormones under water stress, applied through two different growth cond...

Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...
متن کاملUROMYCES SPP. ON MEDICAGO AND TRIFOLIUM SPECIES IN IRAN
In the framework of study on rust fungi of Fabaceae and based on the study of herbarium and newly collected specimens, six Uromyces species are recognized on Medicago spp. and Trifolium spp. from Iran. Among these species, U. fallens is recorded as new member for the Iranian rust flora. U. striatus is recorded as main causal agent of rust on lucerne (Medicago sativa) in Iran. Moreover, U. trifo...

Medicago spp. is the most important forage crop in many regions of the world.Annual medics have distinct advantages over perennial Medicago. These species have fastergrowth rate in cultivation year, higher crude protein percentage, tolerance to pests and morevigorous seedlings. Morphological and physical aspects of pod and seeds of annual medicsplay a major role in the tolerance of the plants t...
متن کاملA role for the mevalonate pathway in early plant symbiotic signaling.
Rhizobia and arbuscular mycorrhizal fungi produce signals that are perceived by host legume receptors at the plasma membrane and trigger sustained oscillations of the nuclear and perinuclear Ca(2+) concentration (Ca(2+) spiking), which in turn leads to gene expression and downstream symbiotic responses. The activation of Ca(2+) spiking requires the plasma membrane-localized receptor-like kinase...
