Absorption of arsenic (As) by plant root is an essential activity that bridges the soil As concentration and physiological responses which can be monitored soon after exposure to As. In the present study, physiological responses to short exposure to arsenite (AsIII) was compared in two indigenous rice cultivars one adapted to temperate and humid (TH) and the second one to warm and humid (WH) cl...

Plants require reliable mechanisms to detect injury. Danger signals or "damage-associated molecular patterns" (DAMPs) are released from stressed host cells and allow injury detection independently of enemy-derived molecules. We studied the response of common bean (Phaseolus vulgaris) to the application of leaf homogenate as a source of DAMPs and measured the production of reactive oxygen specie...

micrornas (mirnas) are small preserved non-coding rna molecules that regulate gene expression post-transcriptionally by targeting the 3' utr of mrnas for translational repression or degradation. the rising evidence has established the significant role of mirnas within the regulation of immune system and the prevention of autoimmunity. mir-146a has obtained an importance as a modulator of d...

Four ecotypes of the species Lycopersicon cheesmanii ssp. minor (Hook.) C.H. Mull. from the Galapagos Islands were compared with L. esculentum Mill cv. VF 36 with respect to salt tolerance. The L. cheesmanii ecotype that proved most salt-tolerant was selected for detailed comparison with the L. esculentum cultivar. Plants were grown in modified Hoagland solution salinized with synthetic seawate...

Creeping bentgrass ( Agrostis stolonifera ) is a desirable turfgrass putting green species that susceptible to drought stress. Planting drought-resistant creeping will enhance the resilience of golf turf surfaces, lower required resource inputs, and reduce environmental impact courses. cultivar performance data during stress are needed for informed selection appropriate cultivars. We evaluated ...

one of the problems associated with adaptive fir filters in the identification of systems with long impulse responses, is their excessive computational complexity. recently a new kind of adaptive filters, based on three-level clipping of the input signal has been presented for reduction of their computational complexity. in this paper, a theoretical analysis of the steady-state misalignment of ...

field in spawn beds. In autumn, when the canes have matured and are dormant, they are lifted from the beds with roots and placed into cold store. When adequate chilling has been accumulated, the longcanes are brought out of the cold store and planted for cropping under the protection of either polytunnels or glass. Production can either precede the main season, by removing the canes from storag...

In this study, resistance responses were investigated during the interaction of Botrytis fabae with two faba bean cultivars expressing different levels of resistance against this pathogen, Nubaria (resistant) and Giza 40 (susceptible). Disease severity was assessed on leaves using a rating scale from 1 to 9. Accumulation levels of reactive oxygen species (ROS), lipid peroxidation and antioxidan...
