Improvement of small seed for big nutritional feed

Foxtail millet research in supporting climate change resilience efforts: Bibliometric analysis and focused literature review

Foxtail millet is part of the millet group but is less popular than sorghum and pearl millet. Nevertheless, the potential of this plant is considered promising for diversifying food nutrition, health products, feed, biofuel, and several other uses, as indicated by various publications, including review articles. However, studies, analyses, and development trends of foxtail millet are lacking, and the current development status of foxtail millet and future projections cannot be systematically identified. Bibliometric analysis offers a method to clarify the current state of the development and interaction of a study topic for systematic analysis. Therefore, this study conducted a bibliometric review to examine the development, interaction, and projections of foxtail millet research regarding publication trends, countries involved, and keywords. Publications related to foxtail millet were first mined from the Scopus database and analyzed using Biblioshiny R Studio and VOSviewer software, with 2091 Scopus documents identified as being associated with the topic of foxtail millet. A significant development occurred in 2012 when the entire foxtail millet genome was explored. The main countries that focus on developing foxtail millet are China and India. The development of foxtail millet is focused on optimizing omics-based approaches to support the use of its potential, especially in research efforts involving climate change tolerance systems. Therefore, innovation, exploration, and potential use of foxtail millet in the future will continue to develop along with submarginal land and public health problems, including in Indonesia, which has the fourth largest population globally.

The role of omics in improving the orphan crop tef

Tef or teff [Eragrostis tef (Zucc.) Trotter] is a cereal crop indigenous to the Horn of Africa, where it is a staple food for a large population. The popularity of tef arises from its resilience to environmental stresses and its nutritional value. For many years, tef has been considered an orphan crop, but recent research initiatives from across the globe are helping to unravel its undisclosed potential. Advanced omics tools and techniques have been directed toward the exploration of tef's diversity with the aim of increasing its productivity. In this review, we report on the most recent advances in tef omics that brought the crop into the spotlight of international research.

Nourishing the Cognition with Millets: A Comprehensive Review of Their Nutritional Impact and Potential as Cognitive Enhancers

Cognition is the mental processes and abilities involved in acquiring, storing, retrieving and using it for decision making. Cognitive decline due to aging, lifestyle factor, chronic health conditions, genetic, and environmental factors are rising global concern and propose a potential threat to the cognitive health. The nutritional imbalance has led to increase in cognitive disorders around the world. Millets can be a nutritional intervention for promoting cognitive health and preventing cognitive decline. Millets has abundant phenolic compounds, flavonoids, and antioxidants to protect against oxidative stress-induced cognitive impairment. Millets exert neuroprotective effects by modulating pathways involved in neuronal-survival, synaptic-plasticity, and release of brain-derived neurotrophic factor. Millets demonstrates anti-inflammatory properties by regulating inflammatory-pathways and suppressing cytokines associated with cognitive impairment. Millets maintain healthy gut microbiota by producing metabolites such as short-chain fatty acids, which influence brain function and cognition. However, further research is needed to elucidate the underlying mechanisms and on optimizing the proportion do exploit its potential. Implementing millet-based dietary strategies through public health initiatives and educational programs can be a practical approach to support cognitive health across populations. Harnessing the potential of millets as a nutritional intervention offers a promising avenue for promoting cognitive health and improving the quality of life.

Vigour testing for the rice seed with computer vision-based techniques

Rice is the staple food for approximately half of the world's population. Seed vigour has a crucial impact on the yield, which can be evaluated by germination rate, vigor index and etc. Existing seed vigour testing methods heavily rely on manual inspections that are destructive, time-consuming, and labor-intensive. To address the drawbacks of existing rice seed vigour testing, we proposed a multispectral image-based non-destructive seed germination testing approach. Specifically, we collected multispectral data in 19 wavebands for six rice varieties. Furthermore, we designed an end-to-end pipeline, denoted as MsiFormer (MisFormer cod3e will be available at https://github.com/LiaoYun0x0/MisFormer) by integrating a Yolo-based object detector (trained Yolo v5) and a vision transformer-based vigour testing model, which effectively improved the automation and efficiency of existing techniques. In order to objectively evaluate the performance of the proposed method in this paper, we conduct a comparison between MisFormer and other 3 deep learning methods. The results showed that, MisFormer performed much better with the accuracy of 94.17%, which was 2.5%-18.34% higher than the other 3 deep learning methods. Besides MsiFormer, possibilities of CIELab mediated image analysis of TTC (tetrazolium chloride) staining in rice seed viability and nCDA (normalized canonical discriminant analysis) in rice seed vigour were also discussed, where CIELab L* of TTC staining were negatively correlated with vigor index and germination rate, with Pearson's correlation coefficient of -0.9874, -0.9802 respectively, and CIELab A* of TTC staining were and positively correlated with vigor index and germination rate, with Pearson's correlation coefficient of 0.9624, 0.9544 respectively, and CIELab A* of nCDA had Pearson's correlation coefficient of -0.8866 and -0.9340 with vigor index and germination rate, respectively. Besides testing methods, vigour results within and among variety(ies) showed that, there were great variations among the 6 rice varieties, and mean coefficient of variation (CV) of vigor index of individual seed within a variety reached 64.87%, revealing the high risk of conventional methods in random sampling. Vigour variations had close relationship with wavelengths of 780 nm-970 nm, indicating their value in future research.

Finger Millet (Eleusine coracana) Plant-Endophyte Dynamics: Plant Growth, Nutrient Uptake, and Zinc Biofortification

Endophytic fungi and bacteria were isolated from finger millet and their effects on finger millet growth parameters and zinc and NPK contents in grains were studied. Out of 70 fungal and 112 bacterial endophytes, the two best fungal and bacterial isolates were selected on the basis of zinc solubilization and plant-growth-promoting attributes. The fungal isolates identified were Aspergillus terreus and Lecanicillium sp., and the bacterial isolates were Pseudomonas bijieensis and Priestia megaterium. The endophytic zinc, NPK mobilization, and plant-growth-promoting efficacy were determined in a pot experiment with zinc carbonate as the zinc source. Endophytic-primed plants showed enhanced shoot and root lengths compared to the unprimed control. Endophytes increased the zinc content in grains by between 12.12% and 18.80% compared to control plants. Endophytes also augmented the NPK concentrations in seeds compared to control plants and exhibited stability in a diverse range of pHs, temperatures, and NaCl concentrations, and exhibited growth on various carbohydrate and nitrogen sources. This is the first study reporting the interaction of Aspergillus terreus, Lecanicillium sp., Pseudomonas bijieensis, and Priestia megaterium with finger millet for grain Zn biofortification and NPK concentration enhancement. This study indicated that zinc-dissolving endophytes possess the potential for enhancing the zinc and NPK content in grains in addition to the plant-growth-promoting attributes.
