“…PIF functions as a central hub for intracellular signal regulation, participating not only in plant growth and development but also in abiotic stress resistance, such as coping with low and high temperatures. 36 While their primary role is in light sensing and signaling, they also engage in responses to thermal stress. A pivotal domain found in phytochromes is the “Histidine kinase A (phosphoacceptor) domain.” This domain is instrumental in phosphorylation events where a histidine residue is autophosphorylated in response to specific cues, including light and potentially thermal stimuli.…”

Pearl millet (Pennisetum glaucum (L.)) is a remarkable cereal crop known for its ability to thrive in challenging environmental conditions. Despite its resilience, the intricate molecular mechanisms behind its toughness remain a mystery. To address this knowledge gap, we conducted advanced next-generation RNA sequencing. This approach allowed us to compare the gene expression profiles of pearl millet seedlings exposed to heat stress with those grown under standard conditions. Our main focus was on the shoots of 13-day-old pearl millet plants, which we subjected to a brief heat stress episode at 50°C for 60 seconds. Within the vast genomic landscape comprising 36 041 genes, we successfully identified a set of 10 genes that exhibited significant fold changes, ranging from 11 to 14-fold compared to the control conditions. These 10 genes were previously unknown to have such substantial changes in expression compared to the control. To uncover the functional significance hidden within these transcriptomic findings, we utilized computational tools such as MEME, String, and phylogenetic tree analysis. These efforts collectively revealed conserved domains within the transcriptomic landscape, hinting at potential functions associated with these genetic sequences. Of particular note, the distinct transcriptomic patterns specific to pearl millet leaves under thermal stress shed light on intricate connections to fundamental biological processes. These processes included the Ethylene-activated signaling pathway, Regulation of intracellular signal transduction, Negative regulation of signal transduction, Protein autophosphorylation, and Intracellular signal transduction. Together, these processes provide insight into the molecular strategies employed by pearl millet to overcome thermal stress challenges. By integrating cutting-edge RNA sequencing techniques and computational analyses, we have embarked on unraveling the genetic components and pathways that empower pearl millet’s resilience in the face of adversity. This newfound understanding has the potential to not only advance our knowledge of plant stress responses but also contribute to enhancing crop resilience in challenging environmental conditions.

“…However, our N. tabacum seed gene expression pattern analysis does not provide any evidence for PIF4’s involvement in the mode of action of different GPAWs. Depending on the species, plants contain a varying set of PIFs, with eight members in A. thaliana and a similar number in Solanaceous species [ 48 ]. Future work may focus on identifying the PIF regulators involved in mediating light responses during tobacco seed germination ( Figure 7 ).…”

Seeds sense temperature, nutrient levels and light conditions to inform decision making on the timing of germination. Limited light availability for photoblastic species results in irregular germination timing and losses of population germination percentage. Seed industries are therefore looking for interventions to mitigate this risk. A growing area of research is water treated with gas plasma (GPAW), in which the formed solution is a complex consisting of reactive oxygen and nitrogen species. Gas plasma technology is widely used for sterilisation and is an emerging technology in the food processing industry. The use of the GPAW on seeds has previously led to an increase in germination performance, often attributed to bolstered antioxidant defence mechanisms. However, there is a limited understanding of how the solution may influence the mechanisms that govern seed dormancy and whether photoreceptor-driven germination mechanisms are affected. In our work, we studied how GPAW can influence the mechanisms that govern photo-dependent dormancy, isolating the effects at low fluence response (LFR) and very low fluence response (VLFR). The two defined light intensity thresholds affect germination through different phytochrome photoreceptors, PHYB and PHYA, respectively; we found that GPAW showed a significant increase in population germination percentage under VLFR and further described how each treatment affects key physiological regulators.

“…Ethylene responsive element binding protein (EREBP) belongs to the AP2/ERBP family of transcription factors and contains the AP2/ERBP domain ( Riechmann and Meyerowitz, 1998 ). The cis-operating elements derived from EREBP transcription factors are different, which can be divided into two large subfamilies, DREB subfamily and the ERF subfamily member: The DREB subfamily can contain dehydration responsive elements/C repeat (DRE/CRT) identify ( Saud et al, 2022 ) ERF sub-family member can identify GCC-box. Therefore, they play a very important role in the process of plant resistance to abiotic stress, and they are also a key regulator of abiotic stress resistance, the more is currently being introduced into adaptation to adversity ( Gao et al, 2009 ).…”

Abiotic stress is an important factor affecting the normal growth and development of plants and crop yield. To reduce the impact of abiotic adversity on cotton growth and development, the material basis of cotton resistance and its physiological functions are analyzed at the molecular level. At the same time, the use of genetic engineering methods to recombine resistance genes has become a hot spot in cotton resistance research. This paper provides an overviews of the resistance mechanism of cotton against the threat of non-biological adversity, as well as the research progress of osmoregulation-related genes, protein-acting genes, and transcription regulatory factor genes in recent years, and outlines the explored gene resources in cotton resistance genetic engineering, with the aim to provide ideas and reference bases for future research on cotton resistance.
