Legumes are highly important food, feed and biofuel crops. With few exceptions, they can enter into an intricate symbiotic relationship with specific soil bacteria called rhizobia. This interaction results in the formation of a new root organ called the nodule in which the rhizobia convert atmospheric nitrogen gas into forms of nitrogen that are useable by the plant. The plant tightly controls ...

objective: osteopontin (opn) has been proposed to play a role in bone resorption. with regard to bone and cementum/dentin structural and histological similarities, it was hy-pothesized that expression of this gene might be increased in resorptive lacunae during orthodontic tooth movement. materials and methods: fixed nickel-titanium closed coil springs (dentaurum ® ) capa-ble of delivering appr...

BACKGROUND Dorsal root ganglion neuron-derived immortal cell lines including ND7/23 and F-11 cells have been used extensively as in vitro model systems of native peripheral sensory neurons. However, while it is clear that some sensory neuron-specific receptors and ion channels are present in these cell lines, a systematic comparison of the molecular targets expressed by these cell lines with th...

plasma membrane h+-atpase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. to study the effect of nacl on the expression pattern of a gene encoding the plasma membrane h+-atpase, an experiment was carried out in a completely random design with three replications. a pair of specific primers was designed based on the sequence o...

Root cDNA libraries were differentially screened to isolate water deficit-responsive transcripts in the relatively drought-resistant plant tepary bean (Phaseolus acutifolius). A novel root-specific, water deficit-responsive transcript was identified and predicted to encode a bZIP transcription factor. The orthologous form of this gene was isolated from the drought-sensitive P. vulgaris and the ...

Calcium signaling plays an important role in adaptation and developmental processes in plants and animals. A class of calcium sensors, known as Calcineurin B-like (CBL) proteins sense specific temporal changes in cytosolic Ca(2+) concentration and regulate activities of a group of ser/thr protein kinases called CBL-interacting protein kinases (CIPKs). Although a number of CIPKs have been shown ...
