Introduction to Desiccation Response

What is/are Desiccation Response?

Desiccation Response - Confirmatory studies using qRT-PCR determined that, though the secondary desiccation response genes were upregulated in C. ^[1] differentially expressed genes (DEGs) related to stress, water deprivation, and desiccation response were repressed in drought treated GhWOX4-virus-induced gene silencing (VIGS) plants as compared to control. ^[2] This work aims at investigating the desiccation response of the multidrug-resistant A. ^[3] We then compared desiccation responses to environmental, habit, fruit and seed characteristics to identify the most useful predictors of desiccation sensitivity. ^[4] Here we survey the recent knowledge gathered from the sequenced genomes of angiosperm and non-angiosperm desiccation-tolerant plants (resurrection plants) and highlight some distinct genes and gene families that are central to the desiccation response. ^[5] , the Radiation and Desiccation Response (RDR)) have been identified in this organism, the role of post-transcriptional regulators has not been characterized within the IR response. ^[6] RDR regulon is operated through cis -acting sequence RDRM (Radiation Desiccation Response Motif), trans -acting repressor DdrO and protease IrrE (also called PprI). ^[7] Stomata and water relations of tissue culture medium determine the successful production of in vitro plants, therefore this experiment was conducted to investigate the effect of two types of gelling agents (Agar and Gelrite) on the stomatal characteristics, transpiration rate (E), and desiccation responses of in vitro walnut explants. ^[8] We summarize information collected from ~600 desiccation-tolerant land plants and discuss the taxonomic distribution and physiology of desiccation responses. ^[9] A series of experiments were conducted for assessing the desiccation responses of leaves of six fruit crops by employing chlorophyll fluorescence imaging, which reveals PS-II efficiency. ^[10] However, trehalose does not contribute directly to the PAO1 desiccation response. ^[11] This pathway, called radiation/desiccation response, is controlled by metallopeptidase IrrE and repressor DdrO that are highly conserved in Deinococcus. ^[12] We confirm that DdrD belongs to the Radiation Desiccation Response (RDR) regulon protein family whose expression is regulated by the IrrE/DdrO proteins after DNA damage. ^[13] In radiation-resistant Deinococcus bacteria, the radiation/desiccation response is controlled by two proteins: the XRE family transcriptional repressor DdrO and the COG2856 metalloprotease IrrE. ^[14] A network containing 22 modules was constructed and seven modules were found to be significantly related to desiccation response by enrichment analysis. ^[15] Because laboratory lineages of these species originated from habitats characterised by different wet/dry regimes, we suggest that the desiccation responses identified here may be representative for the entire taxon. ^[16] For example, only a few Deinococcus-specific proteins and radiation resistance-associated regulatory proteins are present in each Deinococcus, notably the metallopeptidase/repressor pair IrrE/DdrO that controls the radiation/desiccation response regulon. ^[17] The mutagenesis studies confirm that succinylation regulates the enzymatic activities of species‐specific proteins PprI and DdrB, which belong to the radiation–desiccation response regulon. ^[18] Following recovery, the abundance of stress-responsive proteins returned either partially or completely to their baseline level, confirming their importance to the seedling's desiccation response. ^[19] Native trees from the Caribbean were tested for seed desiccation responses, by adapting the “100-seed test” protocol. ^[20]

Radiation Desiccation Response

RDR regulon is operated through cis -acting sequence RDRM (Radiation Desiccation Response Motif), trans -acting repressor DdrO and protease IrrE (also called PprI). ^[1] We confirm that DdrD belongs to the Radiation Desiccation Response (RDR) regulon protein family whose expression is regulated by the IrrE/DdrO proteins after DNA damage. ^[2]

desiccation response regulon

For example, only a few Deinococcus-specific proteins and radiation resistance-associated regulatory proteins are present in each Deinococcus, notably the metallopeptidase/repressor pair IrrE/DdrO that controls the radiation/desiccation response regulon. ^[1] The mutagenesis studies confirm that succinylation regulates the enzymatic activities of species‐specific proteins PprI and DdrB, which belong to the radiation–desiccation response regulon. ^[2]
