Although desiccation tolerance in seeds is common in higher plants, desiccation tolerance in vegetative tissues is restricted to the unique group of resurrection plants... 2018. Perspectives on structural, physiological, cellular, and molecular responses to desiccationin resurrection plants. Scientifica 2018:9464592An in-depth review of cell wall composition... The unique ability of plants to withstand the oxidative stress imposed by reactive oxygen species during desiccation depends on the production of antioxidants. The protection system in desiccation-tolerant plants represents an intricate network of multigenic and multi-factorial processes which modulate a wide array of physiological, morphological... 338 ABSTRACT In this chapter, we review the current understanding of desiccation tolerance in the vegetative tissues of resurrection plants. Desiccation-tolerant plants that retain their photosyn-thetic apparatus in the dried state are termed ho-moiochlorophyllous. Plants that require a slow rate of water loss to survive desiccation... Desiccation definition biology. Desiccationinplants. What does desiccated means in medical terms? The ability of vegetative plant tissues to withstand desiccation is a property of a small group of resurrection plants specific to specialized ecological niches. When the precursors of higher plants first appeared on land - species without any water-conducting organs - desiccation stress became a possibility and a threat. Vegetative desiccation tolerance occurs in a unique group of species termed ‘resurrection plants’. Here, we review the molecular genetic, physiological, biochemical, ultrastructural and... Understanding plantdesiccation tolerance. studies (i.e., transcriptome, proteome, and metabolome) that has been performed on a variety of resurrection plants. 4.5.1. Lack of a morpho-anatomical syndrome in desiccation-tolerant vascular plants. 4.5.2. Important adaptive morpho-anatomical traits. During the initial plantdesiccations and associated analysis, we noticed that a small amount of sand stuck to the buried fragments and fragments desiccated on top of sand. Desiccation-tolerant plants are defined by their ability to survive tissue water potential of at least −100 MPa (equilibration to a relative humidity, RH, of 50%), then recover and resume normal...
