Introducing CRISPR-TSKO: A Breakthrough in Precision Gene Editing
Research, The Plant Cell, The Plant Cell: In BriefAn excellent way to explore the function of a gene is to knockout its expression and see what happens. The development of the targeted gene editing system CRISPR (clustered regularly interspaced short palindromic repeats) has triggered scores of gene knockout studies. CRISPR is based on a defense system…
A Simple and sensitive SYBR Gold-based assay to quantify DNA-Protein interactions ($) (Plant Molecular Biology)
Plant Science Research WeeklyGene regulation occurs at multiple levels including transcription. During transcription, transcriptional factors bind to specific target sequence which allows the recruitment of other proteins including RNA polymerase that enables transcription. Understanding such an intricate mechanism allows researchers…
Fine control of aerenchyma and lateral root development through Aux/IAA- and ARF-dependent auxin signaling ($) (PNAS)
Plant Science Research WeeklyAuxin plays a major role in plant development and can alter the developmental program following the stress response. In this paper, Yamauchi et al., have identified the auxin signaling cascade involved in the development of aerenchyma and regulators of this auxin signaling might also be involved in lateral…
Auxin-sensitive AUX/IAA proteins mediate drought tolerance in Arabidopsis by regulating glucosinolates levels ($) (Nature Communication)
Plant Science Research WeeklyGlucosinolates are secondary metabolites synthesized by plants as a defense compound against pathogen and herbivore. In this paper Salehin et al., have demonstrated regulation of aliphatic glucosinolate levels by auxin signaling that promotes drought tolerance in Arabidopsis. The Aux/IAA proteins are…
Flexibility of intrinsically disordered degrons in AUX/IAA proteins reinforces auxin receptor assemblies ($) (BioRxiv)
Plant Science Research WeeklyAuxin is involved in multiple plant development and stress response which necessitates complexity in auxin signaling. Auxin at a particular threshold in the cells brings together the TIR1/AFB1-5 (TRANSPORT INHIBITOR RESPONSE1/ AUXIN SIGNALING F-BOX 1-5) members and members of the 29 Aux/IAA members bound…
Minimal auxin sensing levels in vegetative moss stem cells revealed by a ratiometric reporter ($) (New Phytologist)
Plant Science Research WeeklyAuxin plays multiple developmental roles from embryogenesis to seed development. To understand the mechanism of auxin response in plants, researchers utilize the early-diverging land plant models, Physcomitrella patens and Marchantia polymorpha. In this paper, Thelander et al., have identified a…
Design principles of a minimal auxin response system ($) (BioRxiv)
Plant Science Research WeeklyAuxin signaling components are evolutionarily conserved across the land plants and the duplication events in these regulators enabled complexity in development. Auxin regulated developmental programming occurs through the ARF (AUXIN RESPONSE FACTORS) transcriptional factors. Marchantia polymorpha serves…
