“…EU-FTF-6 has been shown to mitigate the effect of drought stress by inducing the accumulation of glycine betaine, proline, and sugars, and decreasing lipid peroxidation in foxtail millet ( Kour et al, 2020 ). A recent study discussed various genomic designing approaches for foxtail millet for abiotic stress tolerance ( Rana et al, 2021 ).…”

Millets constitute a significant proportion of underutilized grasses and are well known for their climate resilience as well as excellent nutritional profiles. Among millets, foxtail millet (Setaria italica) and its wild relative green foxtail (S. viridis) are collectively regarded as models for studying broad-spectrum traits, including abiotic stress tolerance, C4 photosynthesis, biofuel, and nutritional traits. Since the genome sequence release, the crop has seen an exponential increase in omics studies to dissect agronomic, nutritional, biofuel, and climate-resilience traits. These studies have provided first-hand information on the structure, organization, evolution, and expression of several genes; however, knowledge of the precise roles of such genes and their products remains elusive. Several open-access databases have also been instituted to enable advanced scientific research on these important crops. In this context, the current review enumerates the contemporary trend of research on understanding the climate resilience and other essential traits in Setaria, the knowledge gap, and how the information could be translated for the crop improvement of related millets, biofuel crops, and cereals. Also, the review provides a roadmap for studying other underutilized crop species using Setaria as a model.

“…It is a diploid C 4 crop with a small genome (~423Mb), less repetitive DNA, short reproductive period, which makes it a model crop for small Panicoid grass crops (Zhang et al, 2012;Kumar et al, 2013). Since the arid and semi-arid condition is the main growth area and in turn is the critical environmental challenge, foxtail millet leaves have evolved synchronously with thick cell walls, small leaf area, neatly arranged epidermal cells, and high water utilization thereby making it climateresilient to abiotic stresses like salt and drought stress (Choudhary and Padaria, 2015;Rana et al, 2021).…”

“…Moreover, drought disaster has become Northeast-forward in China to hinder plant development, which is the main crop production area (Du et al, 2022). Although, foxtail millet has the ability to resist water deficit to some extent, but it is still been affected both at the seedling stage and peak inflorescence stages; and the direct effect is a serious reduction of yield (Rana et al, 2021).…”

Although foxtail millet, as small Panicoid crop, is of drought resilient, drought stress has a significant effect on panicle of foxtail millet at the yield formation stage. In this study, the changes of panicle morphology, photosynthesis, antioxidant protective enzyme system, reactive oxygen species (ROS) system, and osmotic regulatory substance and RNA-seq of functional leaves under light drought stress (LD), heavy drought stress (HD), light drought control (LDCK) and heavy drought control (HDCK) were studied to get a snap-shot of specific panicle morphological changes, physiological responses and related molecular mechanisms. The results showed that the length and weight of panicle had decreased, but with increased empty abortive rate, and then yield dropped off 14.9% and 36.9%, respectively. The photosynthesis of millet was significantly decreased, like net photosynthesis rate, stomatal conductance and transpiration rate, especially under HD treatment with reluctant recovery from rehydration. Under LD and HD treatment, the peroxidase (POD) was increased by 34% and 14% and the same as H2O2 by 34.7% and 17.2% compared with LDCK and HDCK. The ability to produce and inhibit O2- free radicals under LD treatment was higher than HD. The content of soluble sugar was higher under LD treatment but the proline was higher under HD treatment. Through RNA-seq analysis, there were 2,393 and 3,078 different genes expressed under LD and HD treatment. According to the correlation analysis between weighted gene coexpression network analysis (WGCNA) and physiological traits, the co-expression network of several modules with high correlation was constructed, and some hub genes of millet in response to drought stress were found. The expression changes relating to carbon fixation, sucrose and starch synthesis, lignin synthesis, gibberellin synthesis, and proline synthesis of millet were specifically analyzed. These findings provide a full perspective on how drought affects the yield formation of foxtail millet by constructing one work model thereby providing theoretical foundation for hub genes exploration and drought resistance breeding of foxtail millet.
