What are the functions of NATA1 in arabidopsis?
Best insight from top research papers
NATA1 in Arabidopsis has multiple functions. It catalyzes the acetylation of putrescine to N-acetylputrescine, competing with spermidine synthase for a common substrate . NATA1 expression is induced by the defense signaling molecule jasmonic acid and the effector molecule coronatine, suggesting a role in suppressing antimicrobial defenses . The absence of NATA1 results in reduced accumulation of acetylputrescine, elevated H2O2 production by polyamine oxidases, and higher expression of genes related to pathogen defense, leading to improved growth of Pseudomonas syringae, a plant pathogen . Additionally, NATA1 is involved in stress responses and plant development, as loss of NAA50 expression, an interactor of NATA1, results in severe growth retardation and infertility in Arabidopsis . These findings highlight the important role of NATA1 in polyamine metabolism, stress responses, and defense against pathogens in Arabidopsis.

What is the function of PDF1.2 in arabidopsis?4 answersPDF1.2 in Arabidopsis is a transcriptional activator involved in plant stress responses. It is regulated by the antagonistic function of ethylene insensitive3 (EIN3) and EIN3-Like1 (EIL1) transcription factors. EIN3 and EIL1 have opposing effects on the protein levels of the PDF1.2 transcriptional activator octadecanoid-responsive Arabidopsis59 (ORA59). Jasmonic acid (JA) induces ORA59 protein levels independently of EIN3/EIL1, while salicylic acid (SA) reduces the protein levels dependently on EIN3/EIL1. EIN3 physically interacts with ORA59 and targets it for degradation by the 26S proteasome. This interaction between EIN3 and ORA59 is responsible for the SA-responsive reduction of ORA59 levels, highlighting the role of ORA59 as a coordination node for the antagonistic function of ethylene/JA and SA.
What is the role of RG-I side-chains in Arabidopsis?3 answersRG-I side-chains in Arabidopsis play a role in modulating the water-binding capacity (WBC) of potato cell walls (PCW). Exo-truncation of RG-I β-(1→4)-D-galactan side-chains decreased the WBC by 6-9% in vivo, while in vitro exo-truncation increased the WBC by 13%. This suggests that degradation of RG-I galactan side-chains alters the WBC of PCW, possibly by affecting polysaccharide architecture and interactions in the cell wall matrix. In addition, RG-I enriched pectin in fruit and vegetable products is typically removed during commercial pectin production, but recent research has shown that RG-I enriched pectin with abundant arabinan side-chains can form gels under certain conditions, indicating a potential role for RG-I side-chains in gelation. Furthermore, increasing the length of pectic galactan side-chains in the secondary cell wall of Arabidopsis enhances pectin-cellulose spatial contacts and increases cellulose crystallinity, but also disrupts the cell wall architecture by competing with xyloglucan and the pectic backbone for cellulose interactions.
What is the role of LOB domain-containing protein 11 in plants?5 answersLOB domain-containing protein 11 (LBD11) is a regulator of VASCULAR-RELATED NAC-DOMAIN 7 (VND7) and plays a role in the differentiation of tracheary elements in roots. LBD11 positively regulates both the expression of VND7 and the differentiation of tracheary elements. It directly associates with the upstream sequence of VND7 and promotes its expression during the initiation phase of tracheary element differentiation. LBD11 acts in a positive feedback regulation system that accelerates VND7 expression.

What's the biological function of btn2a1?5 answersBTN2A1 is a surface protein that plays a role in modulating the functions of Vγ9Vδ2 T cells. It has been shown to bind to the Vγ9 chain of the γδ TCR, but its precise role in Vγ9Vδ2 T cell function is not fully understood. Studies have demonstrated that BTN2A1 is required for BTN3A-mediated Vγ9Vδ2 T cell cytotoxicity against cancer cells and that the expression of the BTN2A1/BTN3A1 complex is sufficient to trigger Vγ9Vδ2 TCR activation. Additionally, BTN2A1 has been found to interact with all isoforms of BTN3A and is necessary for BTN2A1 export to the plasma membrane. The interaction between BTN2A1 and BTN3A1 is enhanced by phosphoantigens (pAgs), and the B30.2 domains of both proteins are required for pAg responsiveness. These findings suggest that BTN2A1 is involved in the activation and cytotoxic functions of Vγ9Vδ2 T cells, particularly in response to pAgs.
