Abstract Background Heat shock factors Hsfs and Heat shock proteins Hsps belong to an essential group of molecular regulators involved in controlling cellular processes under normal and stress conditions. The role of Hsfs and Hsps is well known in model plant species under diverse stress conditions. While plants Hsfs are vital components of the signal transduction response to maintain cellular homeostasis, Hsps function as chaperones helping to maintain folding of damaged and newly formed proteins during stress conditions. In lettuce Lactuca sativa , a highly consumed vegetable crop grown in the field and in hydroponic systems, the role of these gene families in response to artificial light is not well characterized. Results Using a genome-wide analysis approach, we identified 32 Hsfs and 22 small heat shock proteins LsHsps in lettuce, some of which do not have orthologs in Arabidopsis, poplar, and rice. Surprisingly, LsHsp70s have three times more members than Arabidopsis and two times more than rice. Interestingly, the lettuce genome triplication did not contribute to the increased number of LsHsp70s genes. The large number of LsHsp70s was the result of genome tandem duplication. Conclusions Our genome-wide analysis provides a detailed identification of Hsfs and Hsps in lettuce. plants maintain homeostasis by.

Interestingly, the lettuce plants maintain homeostasis by triplication did not contribute to the increased number of LsHsp70s genes.

Background
Our genome-wide analysis provides a detailed identification of Hsfs and Hsps in lettuce. Chromosomal location and syntenic region analysis together with our transcriptional analysis under different light conditions provide candidate plants maintain homeostasis by for breeding programs aiming to produce lettuce varieties able to grow healthy under hydroponic systems that use artificial light.
Peer Review reports. Increasing human population, climate change conditions, decrease in water availability, and pressure of pathogens and insects have influenced the way we grow crops. Hydroponics is a viable alternative to crop production that addresses many of these issues [ 1 ]. Vegetables and fruits are the most commonly grown hydroponic crops.

Some of the production and health benefits of lettuce include a short production cycle, small size as well as its rich fiber, vitamins, minerals, and phytochemicals content [ 5 ]. A large fraction of lettuce production is homeostasix hydroponically and indoors, relying on the supply of a nutrient solution and artificial https://digitales.com.au/blog/wp-content/custom/why-building-administrations-have-a-developing-business/sex-marriage-essay.php.
The intensity and properties of light are critical factors that regulate photosynthesis and plant growth. Optimization of nutrients and light throughout the production cycle can provide better growing conditions to indoor hydroponic systems [ 34 ].

However, the constant supply of high-energy radiation in the form of UV or high intensity light can negatively alter not only plant growth and development [ 67 ], but also the transcriptional pattern of gene expression [ 89 ]. Under these conditions, the expression of stress responsive genes is critical to ensure plant fitness and normal development. Two gene families are known to be in the front plants maintain homeostasis by of stress responses in tackling adverse conditions: heat shock factors Hsfs and heat shock proteins Hsps.]
