“…When the aquatic moss F. antipyretica, was dried slowly in 50% relative humidity to reach 25% RWC, the plants survived for one month and an increase in the synthesis of proteins associated with sucrose production was observed [95]. Pretreatment of cell suspensions from S. stapfianus leaves with high concentrations of sucrose for 1 h enhanced the protoplasmic drought tolerance (PDT) markedly from equilibration to <50% RH compared with 86-87% RH for controls.…”

“…The capacity of the antioxidant defence system determines continued functioning (supporting survival) or progressive photo-oxidation (leading to injury) [94]. Nucleoside diphosphate kinase 1, associated with ROS signalling, was markedly higher in dry and in rehydrated plants than in hydrated control samples in the moss Fontinalis antipyretica Hedwig [95].…”

“…Thus eIF1 content may limit the rate of protein synthesis during early induction of desiccation tolerance but eIF1 is in good supply for protein synthesis early in rehydrating leaves. The desiccation-tolerant moss F. antipyretica had low abundance of RNA-binding proteins, elongation factor 1-α and translation initiation factor eIF-4A in dry plants; the level of the former protein remained low on rehydration and recovery whereas the eIF-4A protein accumulated to almost twice the control value [95].…”

“…However, during embryogenesis the ABA insensitive 3 (ABI3)-like factor (PvALF, a putative activator), in conjunction with ABA, disrupts the chromatin structure leading to phas expression [219]. DNA-methylating/demethylating enzymes ('DNMT' DNA methyltransferases/DNA glycoylases) or histone-acetylating/deacetylating enzymes ('HAT' histone acetyl transferases/'HDAC' histone deacetylases) are not evident in proteome-investigations of dehydrating desiccation-tolerant plants [58,76,87,95], suggesting their abundances may be too low to be readily detected.…”

Abstract:The majority of flowering-plant species can survive complete air-dryness in their seed and/or pollen. Relatively few species ('resurrection plants') express this desiccation tolerance in their foliage. Knowledge of the regulation of desiccation tolerance in resurrection plant foliage is reviewed. Elucidation of the regulatory mechanism in resurrection grasses may lead to identification of genes that can improve stress tolerance and yield of major crop species. Well-hydrated leaves of resurrection plants are desiccation-sensitive and the leaves become desiccation tolerant as they are drying. Such drought-induction of desiccation tolerance involves changes in gene-expression causing extensive changes in the complement of proteins and the transition to a highly-stable quiescent state lasting months to years. These changes in gene-expression are regulated by several interacting phytohormones, of which drought-induced abscisic acid (ABA) is particularly important in some species. Treatment with only ABA induces desiccation tolerance in vegetative tissue of Borya constricta Churchill. and Craterostigma plantagineum Hochstetter. but not in the resurrection grass Sporobolus stapfianus Gandoger. Suppression of drought-induced senescence is also important for survival of drying. Further research is needed on the triggering of the induction of desiccation tolerance, on the transition between phases of protein synthesis and on the role of the phytohormone, strigolactone and other potential xylem-messengers during drying and rehydration.

PREMISE Desiccation tolerance (DT) is a widespread phenomenon among land plants, and variable ecological strategies for DT are likely to exist. Using Syntrichia caninervis, a dryland moss and model system used in DT studies, we hypothesized that DT is lowest in juvenile (protonemal) tissues, highest in asexual reproductive propagules (gemmae), and intermediate in adults (shoots). We tested the long‐standing hypothesis of an inherent constitutive strategy of DT in this species. METHODS Plants were rapidly dried to levels of equilibrating relative humidity (RHeq) ranging from 0 to 93%. Postrehydration recovery was assessed using chlorophyll fluorescence, regeneration rates, and visual tissue damage. For each life phase, we estimated the minimum rate of drying (RoDmin) at RHeq = 42% that did not elicit damage 24 h postrehydration. RESULTS DT strategy varied with life phase, with adult shoots having the lowest RoDmin (10‒25 min), followed by gemmae (3‒10 h) and protonema (14‒20 h). Adult shoots exhibited no detectable damage 24 h postrehydration following a rapid‐dry only at the highest RHeq used (93%), but when dried to lower RHs the response declined to <50% of control fluorescence values. Notably, immediately following rehydration (0 h postrehydration), shoots were damaged below control levels of fluorescence regardless of the RHeq, thus implicating damage. CONCLUSIONS Life phases of the moss S. caninervis had a range of strategies from near constitutive (adult shoots) to demonstrably inducible (protonema). A new response variable for assessing degree of DT is introduced as the minimum rate of drying from which full recovery occurs.
