“…In addition to protecting plants from abiotic stresses and thus re-establishing ion and water homeostasis through inducing rapid regulation, stress-induced signaling also induces genome-wide transgenomic reprogramming, which activates additional protective mechanisms such as osmoregulation, detoxification, and the repair of stress-induced damage [ 1 ]. Currently, many transcription factors (TFs) in different plants have been identified via genome-wide analysis, such as NF-Y, WOX, WRKY, bZIP, and NAC [ 6 , 66 , 67 , 68 , 69 ]. Certain key transcription factors involved in plant responses to abiotic stress are summarized in Table 1 .…”

Abiotic stress is the adverse effect of any abiotic factor on a plant in a given environment, impacting plants’ growth and development. These stress factors, such as drought, salinity, and extreme temperatures, are often interrelated or in conjunction with each other. Plants have evolved mechanisms to sense these environmental challenges and make adjustments to their growth in order to survive and reproduce. In this review, we summarized recent studies on plant stress sensing and its regulatory mechanism, emphasizing signal transduction and regulation at multiple levels. Then we presented several strategies to improve plant growth under stress based on current progress. Finally, we discussed the implications of research on plant response to abiotic stresses for high-yielding crops and agricultural sustainability. Studying stress signaling and regulation is critical to understand abiotic stress responses in plants to generate stress-resistant crops and improve agricultural sustainability.

“…The increased expression of genes related to carbohydrate and glycosylated residue metabolisms of virulent amoebae compared with attenuated amoebae correlates with gene expression patterns obtained by comparing virulent HM-1:IMSS and non-virulent Rhaman strains, in the same colon explant model [ 130 ]. The glycosidases encoding genes highly upregulated include: β-galactosidase which catalyzes the hydrolysis of β-galactosides into monosaccharides, as well as α- and β-amylases acting on starch, glycogen, and related polysaccharides and oligosaccharides [ 131 ]. Knock down of genes encoding β-amylases leads to trophozoites that are unable to degrade the mucus layer and therefore, with limitations to invade the human colon [ 130 ].…”

The amoeba parasite Entamoeba histolytica is the causative agent of human amebiasis, an enteropathic disease affecting millions of people worldwide. This ancient protozoan is an elementary example of how parasites evolve with humans, e.g. taking advantage of multiple mechanisms to evade immune responses, interacting with microbiota for nutritional and protective needs, utilizing host resources for growth, division, and encystation. These skills of E. histolytica perpetuate the species and incidence of infection. However, in 10% of infected cases, the parasite turns into a pathogen; the host-parasite equilibrium is then disorganized, and the simple lifecycle based on two cell forms, trophozoites and cysts, becomes unbalanced. Trophozoites acquire a virulent phenotype which, when non-controlled, leads to intestinal invasion with the onset of amoebiasis symptoms. Virulent E. histolytica must cross mucus, epithelium, connective tissue and possibly blood. This highly mobile parasite faces various stresses and a powerful host immune response, with oxidative stress being a challenge for its survival. New emerging research avenues and omics technologies target gene regulation to determine human or parasitic factors activated upon infection, their role in virulence activation, and in pathogenesis; this research bears in mind that E. histolytica is a resident of the complex intestinal ecosystem. The goal is to eradicate amoebiasis from the planet, but the parasitic life of E. histolytica is ancient and complex and will likely continue to evolve with humans. Advances in these topics are summarized here.

“…BMY genes break starch into maltose during fruit ripening, resulting in a sweet flavor (Streb and Zeeman, 2012;Ampa et al, 2017). Based on the significant function of BMY genes in plants, BMY genes have been analyzed in many genomes, such as those of A. chinensis (Ampa et al, 2017), Arabidopsis thaliana (Lao et al, 1999;Monroe and Storm, 2018;Nag et al, 2021), G. max (Hirata et al, 2004), and I. batatas (Zhu et al, 2021). In the present study, we explored the expansion patterns of BMY genes.…”

Solanales, an order of flowering plants, contains the most economically important vegetables among all plant orders. To date, many Solanales genomes have been sequenced. However, the evolutionary processes of polyploidization events in Solanales and the impact of polyploidy on species diversity remain poorly understood. We compared two representative Solanales genomes (Solanum lycopersicum L. and Ipomoea triloba L.) and the Vitis vinifera L. genome and confirmed two independent polyploidization events. Solanaceae common hexaploidization (SCH) and Convolvulaceae common hexaploidization (CCH) occurred ∼43–49 and ∼40–46 million years ago (Mya), respectively. Moreover, we identified homologous genes related to polyploidization and speciation and constructed multiple genomic alignments with V. vinifera genome, providing a genomic homology framework for future Solanales research. Notably, the three polyploidization-produced subgenomes in both S. lycopersicum and I. triloba showed significant genomic fractionation bias, suggesting the allohexaploid nature of the SCH and CCH events. However, we found that the higher genomic fractionation bias of polyploidization-produced subgenomes in Solanaceae was likely responsible for their more abundant species diversity than that in Convolvulaceae. Furthermore, through genomic fractionation and chromosomal structural variation comparisons, we revealed the allohexaploid natures of SCH and CCH, both of which were formed by two-step duplications. In addition, we found that the second step of two paleohexaploidization events promoted the expansion and diversity of β-amylase (BMY) genes in Solanales. These current efforts provide a solid foundation for future genomic and functional exploration of Solanales.
