As a second messenger, Ca(2+) plays a major role in cold induced transduction via stimulus-specific increases in [Ca(2+)]cyt, which is called calcium signature. During this process, CAXs (Ca(2+)/H(+) exchangers) play critical role. For the first time, a putative Ca(2+)/H(+) exchanger GhCAX3 gene from upland cotton (Gossypium hirsutum cv. 'YZ-1') was isolated and characterized. It was highly exp...

Wlhile studying cotyledonal abnormality an unusual type of injury was observed in snap beans which had been carefully hand-picked and handshelled. The injury consisted of one or more transverse breaks which extended partially or completely across the cotyledon, severing the vascular elements, figure 1. Not only was the movement of materials into the seedling impeded by the breaks but the cotyle...

Many primary sensory neurons are polymodal, responding to multiple stimulus modalities (chemical, thermal, or mechanical), yet each modality is recognized differently. Although polymodality implies that stimulus encoding occurs in higher centers, such as the spinal cord or brain, recent sensory neuron ablation studies find that behavioral responses to different modalities require distinct subpo...

trauma or surgery negatively affects the healing process, resulting in a prolonged rehabilitative period. Pain, and specifically, joint effusion (swelling within a joint), have been shown to have deleterious effects such as decreased range of motion, muscle spasm, muscle inhibition, and muscle atrophy. These effects lead to decreased function of the involved body part and an extended rehabilita...

Continuing to fertilize bareroot and container seedlings during the hardening process (from cessation of height growth until lifting) can improve seedling viability. The process of fertilizing during hardening has many names, but in the last decade a new term, nutrient loading, has come into use. The process of nutrient loading seedlings leads to luxury consumption indicated by foliar nitrogen ...

Cold treatments are predominantly used to inhibit decay of stored commodities and to extend their shelf life. Recently, cold treatments have been used successfully to control insect pests, mainly in tropical commodities, providing chilling injury can be avoided. This paper summarises the main uses of cold storage as a quarantine treatment.

The application of short-term stresses or elicitors in seedlings or embryos with high metabolic activity might increase multi-adversity tolerance. Beans seeds cv. IAC-Carioca were exposed to cold shock temperatures (S 7°C 24h) and salicylic acid (SA 0.01 mM 48h) during imbibition to study physiological responses to osmotic stress physiological responses. The seeds were soaked in paper towel imb...

The use of cold as a treatment is as old as the practice of medicine, dating back to Hippocrates. Today, methods of applying cold are more advanced than they were in 400 BC, but the principles and the need for precautions are the same. When you apply cold, the skin will initially feel cold, often followed by relief of pain from the injury. As icing progresses, you will feel a burning sensation,...
