“…Overexpression and knockdown of these genes have been performed in the native or heterologous system to comprehend their function. Methods for stable and efficient transformation of Setaria have been established for reverse genetics analysis of the genes identified from various experiments ( Martins et al, 2015a , b ; Saha and Blumwald, 2016 ; Van Eck, 2018 ; Rathinapriya et al, 2019 ; Nguyen et al, 2020 ; Santos et al, 2020 ; Sood et al, 2020 ). The shoot tip-based genetic transformation method has also been optimized for foxtail millet ( Yang et al, 2021a ).…”

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.

“…Regeneration systems have been established successively in wheat (Triticum aestivum L.) (Parmar et al, 2012), corn (Zea mays L.) (He et al, 2006), rice (Oryza sativa L.) (Binte et al, 2018), barley (Hordeum vulgare L.) (Şener et al, 2014), foxtail millet [Setaria italica (L.) Beauv.] (Rathinapriya et al, 2019), and callus had been able to induce from various explants, such as inflores-cence (Głowacka et al, 2010), stem segments (Aslam et al, 2011), root (Guo et al, 2018), immature embryo (Belide et al, 2017;Salehi et al, 2005), mature embryo (Shahsavari et al, 2010), and hypocotyl (Dong et al, 2019), in previous studies. Young leaves from the base of seedlings are found to be better explant materials than other explants, because they cannot be limited by geographical conditions, growing seasons, and developmental stages.…”

Proso millet (Panicum miliaceum L.) is an important drought-tolerant crop, and recently it has become a research focus because of its health-care and nutrition significance. A study was carried out to investigate callus induction and differentiation and plantlet rooting in Shaanmi 1 and Shaanmi 2 with young leaves of the two varieties. Its result showed that in proso millet, the age of aseptic seedlings could influence on inducing calli from young leaves with the highest callus induction frequency at the seedling age of 7 d. N6 medium performed better in inducing calli from young leaves. There did appear to be no calli on MS medium without 2,4-D, but calli were induced on N6 medium without 2,4-D in Shaanmi 2, with its induction frequency standing 6.45% and no calli were induced on the medium without 2,4-D in Shaanmi 1. With 2,4-D added, there appeared the highest callus induction frequency at a 2,4-D concentration of 3.0 mg L -1 . The optimal medium to induce calli from young leaves in proso millet was N6 medium plus 2,4-D (3.0 mg L -1 ) and KT (0.5 mg L -1 ), with its callus induction frequency at 64.33% (Shaanmi 1) and 68.67% (Shaanmi 2), respectively. The optimal callus differentiation medium was MS medium plus 1.0 mg L -1 6-BA and 0.5 mg L -1 NAA, with its differentiation rate at 87.78% (Shaanmi 1) and 96.29% (Shaanmi 2), respectively. Proline adding at 600 mg L -1 was conducive to callus differentiation. The optimal rooting medium was 1/2MS medium plus NAA (0.1 mg L -1 ), with its rooting rate at 100%.

“…For instance, regeneration rates of 80% to 81% [6], 86% and 98% [5], 81.5% [5] were few among several reports for the peanut plant. There were some in vitro regeneration reports in peanut and other crops using various explant sources including a cotyledonary node in mungbean [7,8], a cotyledonary node in black gram [9,12], deembryonated cotyledons in black gram [13], plumular apices in chickpea [14], immature embryonic axes and cotyledonary nodes in soybean [15], the cotyledonary node in soybean [10], cotyledon in oilseed crop [16], embryo in wheat [17], hypocotyl and cotyledon in cabbage [18], leaf base segment in millet [19], cotyledon and hypocotyl in Brassica oleracea [20], the nodal segment in Cinnamomum camphora [21], cotyledon and cotyledonary node in Toona ciliate [22].…”

Efficient in vitro plantlet regeneration is an important step to successfully transform genes for the improvement of agronomic traits. A combination of 6-benzylaminopurine (BAP) and thidiazuron (TDZ) plant growth regulators was applied to evaluate shoot regeneration capacity whereas α-naphthalene acetic acid (NAA) combination with 6-benzylaminopurine (BAP), and 2, 4-dichlorophenoxyacetic acid (2, 4-D) with 6-benzylaminopurine were tested to optimize root induction for two peanut cultivars. The result showed combination (BAP with TDZ) was found to be effective in promoting shoot. The highest shoot regeneration frequency (93%) was obtained on a medium supplemented with 4 mg/L BAP and 0.5 mg/L TDZ while an average regeneration frequency (87%) was achieved in a medium containing combinations of 2 mg/L BAP with 1 mg/L TDZ. The shooting rate increased for both cultivars as the concentrations of BAP increased and TDZ decreased. The highest rooting rate (93%) was obtained on a medium supplemented with 3.5 mg/L NAA with 2.5 mg/L BAP for both cultivars. The rooting rate increased as the concentration of auxin to cytokinin ratio increased. The maximum rooting rate (83%) was obtained on MS medium supplemented with 0.3 mg/L 2, 4-D with 0.2 mg/L BAP for the cultivar N3. The result indicated that BAP with NAA was much better than BAP with 2, 4-D in rooting rate. Thus, the protocol developed was genotype independent and effective for peanut tissue culture.
