“…Woody bamboos grow quickly and can generate up to 50 Mt of biomass acre −1 y −1 , that could convert into a range of energy products such as charcoal, biogas, and biofuels [ 38 , 41 ]. Feedstock for biofuel development is a major struggle for any nation, as biofuel crops conflict with grain, fodder, and fiber for scarce land resources [ 42 ]. Bamboo species have an estimated annual biomass growth of 22–44 Mt ha −1 y −1 , which is far higher than pine (25–30 Mt ha −1 y −1 ) and equivalent to eucalyptus (30–40 MT ha −1 y −1 ) forests [ 38 ].…”

“…Nevertheless, its total heating value and structure are about that of herbaceous wood and hardwoods. Bamboo has comparable fuel properties to other biomass feedstocks [ 28 , 42 , 44 ]. In thermoelectric plants and the building industry, the bamboo feedstock is used on an industrial scale by direct combustion or cogeneration of heat and electricity [ 38 ].…”

Increasing population, industrialization, and economic growth cause several adverse impacts on the existing environment and living being. Therefore, rising pollutants load and their mitigation strategies, as well as achieving energy requirements while reducing reliance on fossil fuels are the key areas, which needs significant consideration for sustainable environment. Since India has considerable biomass resources, bioenergy is a significant part of the country’s energy policy. However, the selection of feedstock is a crucial step in bioenergy production that could produce raw material without compromising food reserve along with the sustainable environment. Higher growth capacity of bamboo species makes them a suitable lignocellulosic substrate for the production of high-value greener products such as fuels, chemicals, and biomaterials as well as an appropriate candidate for eco-restoration of degraded land. In that context, the current review discusses the multidimensional applications of bamboo species in India. The bioenergy potency of bamboo and probability of aligning its production, cultivation, and operation with economic and social development agendas are also addressed, making it an exceptional crop in India. Additionally, its fast growth, perennial root systems, and capability to restore degraded land make it an essential part of ecological restoration. Furthermore, this review explores additional benefits of bamboo plantation on the environment, economy, and society along with future research prospects.

“…In addition to fodder purpose, the stalks from sorghum are used as an alternative for the production of syrups, jaggery, citric acids and modified starch (Reddy et al, 2005). Due to these multipurpose uses from fodder sorghum, several crop improvement programs were made to maximize biomass production as sorghum is still considered a choice of crop for the marginal environment (Patel et al, 2020). One of the best crop improvement program involves screening the diversity residing in a natural population for identifying the superior genotypes withstanding diverse conditions which can meet up with human needs.…”

Germplasm can be exploited efficiently by determining its genetic diversity and identifying desirable parents for crop improvement programs. In this study, 200 diverse sets of sorghum accessions were evaluated during rabi, 2019 with an aim of assessing genetic diversity for fodder component traits using D 2 statistics. Fresh biomass contributed the highest (47.4%) towards divergence followed by days to flowering (35.9%) and plant height (16.7%). All the 200 genotypes were grouped into 6 clusters with Cluster I having the maximum number of genotypes (108) followed by cluster IV (47), VI (39) and clusters II, III, V having the least genotype number (2). Cluster I had the highest (10.61) intra cluster distance while cluster II had the least (0.41) intra cluster distance. Inter cluster distance between I and IV was observed the highest (10.43) while the least was observed between III and V. Genotypes from Cluster II and IV were observed to be the best suited for fodder improvement programs.

“…It is widely planted all over the world with fast growth, high yield and strong resistance to various environmental stresses. Pearl millet is rich in easy-toextract fermented sugars, which can be used to produce bioethanol, thus, many researchers regard it as a very potential energy plant [4][5][6]. It is also one of the parents of the important energy plant hybridized pennisetum.…”

Background：Seed germination is the most important stage for the formation of a new plant. This process starts when the dry seeds begin to absorb water and ends when the radicles sticks out. The germination rate of different plant seeds varies differently. Most energy plants that usually grow on marginal land, the rapid germination of seeds is more conducive to its superiority in competition with surrounding plants, which is also the guarantee of normal plant development and high yield. Pearl millet is an important cereal crop that shares widespread applications in the world. It has the advantages of fast growth, high yield, and low maintenance cost. It can also be used to extract bioethanol to solve the increasingly prominent energy problems. Previous germination experiments are the evidence of very fast seed germination rate of pearl millet, but the molecular mechanisms behind it is still unclear.Results: Through the germination test and the measurement of the germs and radicles length of the seedlings, we found that pearl millet seeds germinated very quickly after 24 hours of swelling of the dry seeds. By using transcriptome sequencing technology, we characterized the gene expression patterns of dry seeds, water imbibed seeds, germs and radicles of seedlings, and found the more DEGs in radicles than germs. Further analysis showed that different genome clusters function specifically at different tissues and time periods. WGCNA and KEGG enrichment analysis showed that that many genes that positively regulate plant growth and development are highly enriched and expressed, especially the gibberellin signaling pathway that can promote seed germination. We speculated that the activation of these key genes promotes the germination of pearl millet seeds and the growth of seedlings. To verify this inference, we measured the content of the main effect hormone gibberellin and found that the gibberellin content after seed imbibition rose sharply and remained at a high level.Conclusions：This study explored the expression patterns of genes involved in pearl millet growth from the germination of dry seeds to the early growth stages. Also identifies the key genes involved in the regulation of seed germination and seedling growth. The activation of key genes in these pathways may contribute to the rapid germination and growth of seeds and seedlings in pearl millet. These results provide new insights to solve the problem for the plants with slow seed germination and seedling growth.
