Allelic variation is a valuable tool for displaying high levels of polymorphism within species and is closely correlated with crop productivity. In Marathawada, there is a significant amount of phenotypic heterogeneity among sorghum landraces. However, molecular variability needs to be reevaluated in order to identify any potential barriers that can interfere with current improvement initiatives. In the current work, we used 5 SSR markers to categorize 20 genotypes of elite (Sorghum bicolor L. Moench) accession from the Marathwada region, including one standard cultivar from various agro-economic zones. According to the results of this study, 14 alleles were found among the 20 genotypes, with a PIC value that ranged from 0.37 to 0.70 and a mean of 0.44 per locus. Each locus had anything from 1 (gpsb089) and 5 (mSbCIR223), with an average of 2.80 alleles per locus. A neighbor-joining tree was constructed and showed clustering of genotypes into two groups; this indicates that there is considerable diversity in genotypes compared with advanced cultivar for desired genotype (IS1042) by using SSR markers. Results show that most diverse cultivars were IS-4564, IS18357, and IS-18381, and significant variation was also reported in IS4566 and IS18379.

Background: Conserved non-coding sequences (CNS) are islands of non-coding sequences conserved across species and play an important role in regulating the spatiotemporal expression of genes. Identification of CNS provides valuable information about potentially functional genomic elements, regulatory regions, and helps to gain insights into the genetic basis of crop agronomic traits.
Results: Here, we comprehensively analyze CNS in maize, by comparing the genomes of maize inbred line B73 (Zea mays ssp.

Tannin-containing sorghum grains, suitable for acetone-butanol-ethanol (ABE) production by Clostridium acetobutylicum, have required pretreatment to eliminate tannins inhibiting the strain's amylolytic activity. This study investigates biobutanol production enhancement by immobilizing enzymes on polydopamine-functionalized polyethersulfone (PES) membranes with magnetic nanoparticles for Separated Hydrolysis and Fermentation (SHF) and Simultaneous Saccharification and Fermentation (SSF) processes. After multi-stage hot water treatment, TG3 sorghum (from the third stage) was used, where the enzyme-immobilized PES membrane produced 4.

The effect of ensiling sorghum grains harvested at different dates on pig nutrient digestibility and fermentability was evaluated using approaches. A sorghum crop was divided following a randomised complete block design and distributed in 3 treatments: 1) grain harvested 113 d after sowing (40% moisture) and ensiled for 180 d (high moisture, HMG), 2) grain harvested 159 d after sowing (15% moisture), rehydrated to 40% moisture and ensiled for 180 d (reconstituted, REC), and 3) sorghum grain harvested 159 d after sowing (15% moisture) and stored dry (dry, DG). Starch content was lower in ensiled grains (HMG and REC) ( = 0.

Increased soluble salts in soil and irrigation water threaten the sustainability of crops. This causes food insecurity directly by reducing the staple crop yield and indirectly by limiting fodder and forage production. Recently, plant-growth-promoting rhizosphere microorganism utilization improved crop productivity under stress.
