“…Fluctuations in environmental conditions have remarkably influenced carrot growth and development (Huang et al 2015 ; Que et al 2019 ). Several studies described that water deficit is a major abiotic factor in carrot production and it negatively affects carrot yield and quality (Salter and Goode 1967 ; Groves and Bailey 1994 ; Herppich et al 2001 ; Öztürk Gökçe et al 2022 ; Junaid et al 2023a , b ). However, the influence of low soil moisture on carrot taproots is not clear.…”

“…Plants uptake water via roots when there is less water potential in plants compared to outer soil (Taiz and Zeiger 2010 ), such low water potential in plants is known as osmotic stress. Carrot plants exhibit osmotic adjustments when exposed to abiotic stresses including drought, such adjustments include changes in prolines, antioxidant enzymes, and glycine betaine (Öztürk Gökçe et al 2022 ). Synthesis of Osmo protectants in plants enables plants to resist osmotic stress, this is also known as osmotic adjustment (Blum 2017 ).…”

“…Osmo-protectants control cell turgor, water gradient, and water uptake in the cytoplasmic region (Murti et al 2007 ). Different studies reported osmotic adjustment in carrots under abiotic stress (Kamińska et al 2022 ; Junaid et al 2023a ; Öztürk Gökçe et al 2022 ). However, studies are still needed to investigate mechanisms behind osmotic regulation in carrot plants under abiotic stress.…”

“…Previous reports indicate that when plants are exposed to drought stress, essential metabolites such as GB (glycine betaine) and total phenolics exhibit higher levels of accumulation (Ha et al 2012 ). Occurrence of drought stress causes significant increase in GB contents in carrot genotypes (Öztürk Gökçe et al 2022 ). It is well-established that phenolic compounds possess the ability to scavenge reactive oxygen species (ROS) (Weidner et al 2009 ) and they combine with metals to inhibit the enzyme oxidizing activity (Elavarthi and Martin 2010 ).…”

Drought stress is a significant environmental factor that adversely affects the growth and development of carrot (Daucus carota L.), resulting in reduced crop yields and quality. Drought stress induces a range of physiological and biochemical changes in carrots, including reduced germination, hindered cell elongation, wilting, and disrupted photosynthetic efficiency, ultimately leading to stunted growth and decreased root development. Recent research has focused on understanding the molecular mechanisms underlying carrot's response to drought stress, identifying key genes and transcription factors involved in drought tolerance. Transcriptomic and proteomic analyses have provided insights into the regulatory networks and signaling pathways involved in drought stress adaptation. Among biochemical processes, water scarcity alters carrot antioxidant levels, osmolytes, and hormones. This review provides an overview of the effects of drought stress on carrots and highlights recent advances in drought stress-related studies on this crop. Some recent advances in understanding the effects of drought stress on carrots and developing strategies for drought stress mitigation are crucial for ensuring sustainable carrot production in the face of changing climate conditions. However, understanding the mechanisms underlying the plant's response to drought stress is essential for developing strategies to improve its tolerance to water scarcity and ensure food security in regions affected by drought.

Öztürk Gökçe et al [ 16 ] described MYB-48 transcription factor, F-box protein, ferric reduction oxidase, and ABA-induced somatic embryo gene expression upregulation under water deficit. Zhao et al [ 10 ] reported that NAC , MYB , WRKY , homeobox-leucine zipper ( HD-ZIP ) and basic leucine-zipper ( bZIP ) were closely related to the response to PEG osmotic stress in Jerusalem artichoke.…”

Osmotic stress is a condition in which plants do not get enough water due to changes in environmental factors. Plant response to osmotic stress is a complex process involving the interaction of different stress-sensitive mechanisms. Differentially expressed genes and response mechanisms of kohlrabi have not been reported under osmotic stress. A total of 196,642 unigenes and 33,040 differentially expressed unigenes were identified in kohlrabi seedlings under polyethylene glycol osmotic stress. AP2/ERF, NAC and eight other transcription factor family members with a high degree of interaction with CAT and SOD antioxidant enzyme activity were identified. Subsequently, 151 AP2/ERF genes were identified and analyzed. Twelve conserved motifs were searched and all AP2/ERF genes were clustered into four groups. A total of 149 AP2/ERF genes were randomly distributed on the chromosome, and relative expression level analysis showed that BocAP2/ERF genes of kohlrabi have obvious specificity in different tissues. This study lays a foundation for explaining the osmotic stress resistance mechanism of kohlrabi and provides a theoretical basis for the functional analysis of BocAP2/ERF transcription factor family members.
