Unveiling the thermotolerance mechanism of Pichia kudriavzevii LC375240 through transcriptomic and genetic analyses.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThermotolerance is a critical trait for yeasts employed in industrial settings, and the utilization of unconventional yeasts has gained notable attention in recent years. However, the mechanisms underlying thermotolerance in unconventional yeasts, particularly Pichia spp., remain insufficiently elucidated.
resultsThis study focuses on the thermotolerance of a non-traditional yeast strain Pichia kudriavzevii LC375240, renowned for its remarkable thermotolerance. Through transcriptomic analysis of both short-term and long-term heat shock exposures, we uncovered an intricate regulatory response in P. kudriavzevii. During long-term heat treatment, the yeast exhibited elevated expression of genes involved in the tricarboxylic acid (TCA) cycle and suppressed expression of genes in the pentose phosphate pathway (PPP). Additionally, long-term heat treatment led to an upregulation of heat shock proteins (HSPs) and an increase in trehalose, glutathione (GSH), and superoxide dismutase (SOD) levels, along with a reduction in the intracellular NADPH/NADP
conclusionsTaken together, this study demonstrates that P. kudriavzevii adapts to thermal stress through a combination of enhanced TCA cycle, reduced PPP, increased HSPs, trehalose, GSH, and SOD levels. These findings provide a comprehensive understanding of the molecular mechanisms underlying thermotolerance in P. kudriavzevii.
