Trimethylguanosine Synthase1 (TGS1) Is Essential for Chilling Tolerance1[OPEN]
Chilling stress is a major factor limiting plant development and crop productivity. Because the plant response to chilling is so complex, we are far from understanding the genes important in the response to chilling. To identify new genes important in chilling tolerance, we conducted a novel mutant screen, combining a confirmed SALK T-DNA insertion collection with traditional forward genetics. ...

متن کاملA chilling sensitive mutant of Arabidopsis with altered steryl-ester metabolism.
A chilling-sensitive mutant of Arabidopsis thaliana was isolated and subjected to genetic, physiological, and biochemical analysis. The chilling-sensitive nature of the mutant line is due to a single recessive nuclear mutation at a locus designated chs1. In contrast to wild-type plants, which are not adversely affected by low temperatures, the chs1 mutant is killed by several days of exposure t...
متن کاملGene expression phenotypes of Arabidopsis associated with sensitivity to low temperatures.
Chilling is a common abiotic stress that leads to economic losses in agriculture. By comparing the transcriptome of Arabidopsis under normal (22 degrees C) and chilling (13 degrees C) conditions, we have surveyed the molecular responses of a chilling-resistant plant to acclimate to a moderate reduction in temperature. The mRNA accumulation of approximately 20% of the approximately 8,000 genes a...
متن کاملArabidopsis PCaP2 Plays an Important Role in Chilling Tolerance and ABA Response by Activating CBF- and SnRK2-Mediated Transcriptional Regulatory Network
Chilling stress affects plant growth and productivity. However, the multi-underlying mechanisms of chilling tolerance are not well understood. Arabidopsis PCaP2 is involved in regulating the dynamic of microtubules (MTs) and F-actin and Ca2+-binding ability. Here, the results showed that the PCaP2 expression was highly induced in roots, cotyledons, true leaves, lateral roots and flowers under c...
متن کاملChloroplast RNA-Binding Protein RBD1 Promotes Chilling Tolerance through 23S rRNA Processing in Arabidopsis
Plants have varying abilities to tolerate chilling (low but not freezing temperatures), and it is largely unknown how plants such as Arabidopsis thaliana achieve chilling tolerance. Here, we describe a genome-wide screen for genes important for chilling tolerance by their putative knockout mutants in Arabidopsis thaliana. Out of 11,000 T-DNA insertion mutant lines representing half of the genom...
