LTG1 affects rice growth at LT via an auxin-dependent process(es)[1].
Contents
Annotated Information
Function
- A functional nucleotide polymorphism was identified in the coding region of LTG1, causing a single amino acid substitution (I357K) that is associated with the growth rate, heading date and yield of rice plants grown at LT. LTG1 plays an important role in the adaptive growth and fitness of rice cultivars under conditions of low ambient temperature[1].
GO assignment(s): GO:0004672,GO:0004674, GO:0006468, GO:0005524,
Mutation
ltg1 allele[1]:
- Phylogenetic analysis of this locus suggests that the ltg1 haplotype arose before the domestication of rice in tropical climates. LTG1 (Low Temperature Growth 1) allele are more tolerant to LT, than those with the ltg1 allele.
Expression
- The expression of LTG1 is not regulated by temperature, and therefore is unlikely to account for the LT sensitivity. The polymorphism at nucleotide 1070 in LTG1 represents a functional nucleotide polymorphism (FNP) responsible for the LT tolerance of Asominori[1].
- Rice cultivars with the dominant LTG1 allele fit better and had higher yield potential when grown in environments where low temperatures are present during vegetative and reproductive growth[1].
Knowledge Extension
- Low temperature (LT), defined as a low but not freezing temperature (>0°C). Apart from water availability, low temperature is the most important environmental factor limiting the productivity and geographical distribution of plants across the world. To cope with cold stress, plant species have evolved several physiological and molecular adaptations to maximize cold tolerance by adjusting their metabolism[2].
- The regulation of some gene products represents an additional mechanism of cold tolerance. A consequence of these mechanisms is that plants are able to survive exposure to low temperature via a process known as cold acclimation[2].
