NAA enhances cell yields by inhibiting apoptosis pathway

ABSTRACT: The in vitro cell culturing witnessed its applications in both scientific research and industrial activities, its optimization leads to practical benefits, either through shortening the doubling time, or simplification of engineering requests, or both. Literature searching highlighted a role of a synthetic auxin derivative 1-Naphthaleneacetic acid (NAA) in optimizing plant cell culturing. Here, by measuring cell counts and their activities via CCK8 tests, we observed an up to 2-fold increase in the yield of in vitro cultured human cells. We tested different types of human cell lines and primary natural killer cells, found that NAA was effective in all the cells tested. The PI staining and FACS analysis suggested that NAA did not affect the cell cycling. Apoptosis-specific dye staining analysis implicated that NAA rescued cell death. We further did bulk RNA sequencing and identified the lipid metabolism-engaging and anti-apoptosis gene, ANGPTL4, was enhanced in expression upon NAA treatment. Studies on ANGPTL4 knockout cells indicated that ANGPTL4 is required for NAA-mediated response. Thus, our data identified a beneficial role of NAA in human cell culturing and highlighted its potency in the in vitro cell culturing

A transcript profile of Medicago truncatula 2HA tissue culture with auxin treatment

Project description:Leaf explants of the superembryogenic Medicago truncatula line 2HA were treated with auxin (1-naphthaleneacetic acid) for one week to induce the formation of roots (Imin et al J Exp Bot 58:439-451). Gene expression in the leaves and the NAA treated tissue cultures was compared to identify transcripts expressed during the commitment to root formation in tissue culture. We have used the Affymetrix Medicago Genome Array GeneChip to compared gene expression in Medicago truncatula leaves and leaf explants that have been cultured for one week on NAA, to identify genes expressed during the commitment to root formation in tissue culture. Keywords: Cell type comparison

Integrated omics analysis reveals the norisoprenoid responses in Vitis vinifera L. cv. Cabernet Sauvignon berries to abscisic acid and synthetic auxin

Project description:The abscisic acid (ABA) increase and auxin decline are both indicators of ripening initiation in grape berry, and norisoprenoid accumulation also start at around the onset of ripening. To investigate the transcriptional and posttranscriptional regulation of the ABA and synthetic auxin 1-naphthaleneacetic acid (NAA) on norisoprenoid production, we performed time series GC-MS and RNA-seq analyses on Cabernet Sauvignon grape berries from pre-veraison to ripening. Higher levels of free norisoprenoids were found in ABA-treated mature berries in two consecutive seasons, and both free and total norisoprenoids were significantly increased by NAA in one season. The expression pattern of known norisoprenoid-associated genes in all samples and the up-regulation of specific alternative splicing isoforms of VviDXS and VviCRTISO in NAA-treated berries were predicted to contribute to it. Combined weighted gene co-expression network analysis (WGCNA) and promoter motif prediction analysis suggested that GATA26 and GATA28 could be potential regulators of norisoprenoid accumulation. Finally, the network analysis uncovered the interaction between previously identified switch genes, hormone-related genes and norisoprenoid-associated genes.

Expression data from Arabidopsis seedlings upon LRIS using NAA (1-Naphthaleneacetic acid) or non-auxin-like lateral root inducer naxillin

Project description:The acquisition of water and nutrients by plant roots is a fundamental aspect of agriculture and strongly depends on root architecture. Root branching and expansion of the root system is achieved through the development of lateral roots and is to a large extent controlled by the plant hormone auxin. However, the pleiotropic effects of auxin or auxin-like molecules on root systems complicate the study of lateral root development. Here we describe a small-molecule screen in Arabidopsis thaliana that identified naxillin as what is to our knowledge the first non-auxin-like molecule that promotes root branching. By using naxillin as a chemical tool, we identified a new function for root cap-specific conversion of the auxin precursor indole-3-butyric acid into the active auxin indole-3-acetic acid and uncovered the involvement of the root cap in root branching. Delivery of an auxin precursor in peripheral tissues such as the root cap might represent an important mechanism shaping root architecture. To further explore the specificity of naxillin for lateral root development, we compared the early effects of naxillin at the transcriptome level with NAA (1-Naphthaleneacetic acid) in roots of 3-day-old seedlings after 2-h and 6-h treatment. Arabidopsis thaliana (L). Heynh., Col-0 seeds were germinated vertically on solid medium derived from standard MS medium supplemented with 10 μM NPA (1-N-Naphthylphthalamic acid). Three days after germination, plants were transferred to 10 μM NAA (1-Naphthaleneacetic acid) or 50 μM naxillin for 2 and 6 hours. Plants were sampled before (Roots at T0, NPA) or after treatment (Roots at T1 and T2). RNA isolation was performed on 500 root sections (only root without meristems) for each sample. All sampling points were performed in three independent experiments.

Auxin treatment of grapevine (Vitis vinifera L.) berries delays ripening onset by inhibiting cell expansion

Project description:Auxin treatment of grape (Vitis vinifera L.) berries delays ripening by inducing changes in gene expression and cell wall metabolism and could combat some deleterious climate change effects. Auxins are inhibitors of grape berry ripening and their application may be useful to delay harvest to counter effects of climate change. However, little is known about how this delay occurs. The expression of 1892 genes was significantly changed compared to the control during a 48 h time-course where the auxin 1-naphthaleneacetic acid (NAA) was applied to pre-veraison grape berries. Principal component analysis showed that the control and auxin-treated samples were most different at 3 h post-treatment when approximately three times more genes were induced than repressed by NAA. There was considerable cross-talk between hormone pathways, particularly between those of auxin and ethylene. Decreased expression of genes encoding putative cell wall catabolic enzymes (including those involved with pectin) and increased expression of putative cellulose synthases indicated that auxins may preserve cell wall structure. This was confirmed by immunochemical labelling of berry sections using antibodies that detect homogalacturonan (LM19) and methyl-esterified homogalacturonan (LM20) and by labelling with the CMB3a cellulose-binding module. Comparison of the auxin-induced changes in gene expression with the pattern of these genes during berry ripening showed that the effect on transcription is a mix of changes that may specifically alter the progress of berry development in a targeted manner and others that could be considered as non-specific changes. Several lines of evidence suggest that cell wall changes and associated berry softening are the first steps in ripening and that delaying cell expansion can delay ripening providing a possible mechanism for the observed auxin effects.

Transcription profiling of grapevine cell culture treated with methyly jasmonate, salicylic acids and ethanol controls

Project description:Calli generated from grape berries were used to establish a cell suspension in Gamborgs B5 liquid medium with minimal organics supplemented with 30 gL-1 sucrose, 0.25 gL-1 casein hydrolysate, 0.93 ?M kinetin and 0.54 ?M naphthaleneacetic acid (NAA) and incubated in darkness at 26°C. <br>The cells were cultured in 250 mL flasks (50 mL of cell suspension in each) incubated in darkness on an orbital shaker at 100 rpm. The cell suspensions were sub-cultured every 2 weeks using an initial packed cell volume (PCV) of 15%. For the evaluation of the effect of elicitor addition on the changes in gene expression, 100 mL flasks containing 20 mL of the above cell suspension were used. Each treatment was conducted in triplicate.<br><br>In a set of preliminary experiments studying the effect of elicitors on the volatiles produced by the cell suspensions, the compounds were added during the exponential growth phase when the PCV was approximately 50%. After 72h incubation in darkness after elicitor addiction, cells were harvested. The elicitors screened for their ability to induce volatile compound production were: 500 µM methyl jasmonate (MeJA); 500 uM MeJA + 500 µM salicylic acid (SA); 500 µM jasmonic acid (JA). Controls were conducted by adding the same volume of the solvent used to dissolve each elicitor to the cultures. For the jasmonate and SA experiments the solvent was ethanol.<br>
