Strigolactones are involved in root response to low phosphate conditions in Arabidopsis.
Strigolactones (SLs) are plant hormones that suppress lateral shoot branching, and act to regulate root hair elongation and lateral root formation. Here, we show that SLs are regulators of plant perception of or response to low inorganic phosphate (Pi) conditions. This regulation is mediated by MORE AXILLARY GROWTH2 (MAX2) and correlated with transcriptional induction of the auxin receptor TRAN...
متن کاملUpdate on Role of Strigolactones in Root Development, Response, and Interaction Strigolactone Involvement in Root Development, Response to Abiotic Stress, and Interactions with the Biotic Soil Environment
Strigolactones, recently discovered as plant hormones, regulate the development of different plant parts. In the root, they regulate root architecture and affect root hair length and density. Their biosynthesis and exudation increase under low phosphate levels, and they are associated with root responses to these conditions. Their signaling pathway in the plant includes protein interactions and...
متن کاملIdentification and Expression Analysis of Two Arabidopsis LRR-Protein Encoding Genes Responsive to Some Abiotic Stresses
AbstractTwo Arabidopsis thaliana genes, psr9.2 and psr9.4 appearedto be highly similar to a phosphate-starved induced gene,psr9, isolated from Brassica nigra suspension cells.Sequence analysis classified the encoded polypeptides asmembers of leucine-rich repeat (LRR) proteins superfamily.The sequence of psr9 proteins comprise a unique N-terminalregion e...
متن کاملStrigolactones activate different hormonal pathways for regulation of root development in response to phosphate growth conditions.
BACKGROUND Strigolactones (SLs) - a group of plant hormones and their derivatives - have been found to play a role in the regulation of root development, in addition to their role in suppression of lateral shoot branching: they alter root architecture and affect root-hair elongation, and SL signalling is necessary for the root response to low phosphate (Pi) conditions. These effects of SLs have...
متن کاملGene transcriptomic profile in arabidopsis thaliana mediated by radiation-induced bystander effects
Background: The in vivo radiation-induced bystander effects (RIBE) at the developmental, genetic, and epigenetic levels have been well demonstrated using model plant Arabidopsis thaliana (A. thaliana). However, the mechanisms underlying RIBE in plants are not clear, especially lacking a comprehensive knowledge about the genes and biological pathways involved in the RIBE in plants. Materials and...
