Unveiling nature's treasures: actinobacteria from Meghalaya's mining sites as sources of bioactive compounds
This study involved the isolation of actinobacteria from two mining sites in Meghalaya, India. The dominant genera from both sites were Streptomyces, Amycolatopsis, Nocardia, and Streptosporangium. Metabolic pathway prediction from 16S rRNA gene revealed several pathways beneficial for plant growth. Exploration of biosynthetic genes indicated a prevalence of the type-II polyketide synthase gene. Sequencing the ketosynthase-alpha domain of the gene led to predictions of various bioactive secondary metabolites. Around 44% of the isolates demonstrated antimicrobial properties, with some also displaying plant growth-promoting ...

Effect of fermented tomato pomace on the growth performance, antioxidant capacity, and intestinal microflora in broiler chickens
This study was conducted to investigate the effects of tomato pomace (TP) andAspergillus niger-fermented tomato pomace (FTP) on the growth performance, some carcass traits, antioxidant status, and intestinal microflora in broiler chickens. A total of 140 Ross 308 one-day-old male chicks were allocated to one of four treatment groups consisting of five replicates of seven chicks each. Chicks were fed ad libitum with the corn-soybean based basal diet (control), the basal diet supplemented with 0.25 g/kg synthetic antioxidant, 10 g/kg TP or 10 g/kg FTP for 42 days. Dietary TP increased serum glutathione peroxidase (GPx...

Viruses, Vol. 16, Pages 125: Development of Stable Infectious cDNA Clones of Tomato Black Ring Virus Tagged with Green Fluorescent Protein
wska
Tomato black ring virus (TBRV) is a member of the Nepovirus genus in the Secoviridae family, which infects a wide range of important crop species worldwide. In this work, we constructed four cDNA infectious clones of the TBRV tagged with the green fluorescent protein (TBRV-GFP), which varied in (i) the length of the sequences flanking the GFP insert, (ii) the position of the GFP insert within the RNA2 polyprotein, and (iii) the addition of a self-cutting 2A protein. The presence of the GFP coding sequence in infected plants was verified by RT-PCR, while the infectivity and stability of the constructs were verified...

Unusual outbreaks of curly top disease in processing tomato fields in northern California in 2021 and 2022 were caused by a rare strain of beet curly top virus and facilitated by extreme weather events
Virology. 2024 Mar;591:109981. doi: 10.1016/j.virol.2024.109981. Epub 2024 Jan 4.ABSTRACTIn the western United States, curly top disease (CTD) is caused by beet curly top virus (BCTV). In California, CTD causes economic loss to processing tomato production in central and southern areas but, historically, not in the north. Here, we document unusual CTD outbreaks in processing tomato fields in the northern production area in 2021 and 2022, and show that these were caused by the rare spinach curly top strain (BCTV-SpCT). These outbreaks were associated with proximity of fields to foothills and unusually hot, dry, and windy sp...

Exploration of a multifunctional biocontrol agent Streptomyces sp. JCK-8055 for the management of apple fire blight
Appl Microbiol Biotechnol. 2024 Dec;108(1):1-19. doi: 10.1007/s00253-023-12874-w. Epub 2024 Jan 6.ABSTRACTApple fire blight, caused by the bacterium Erwinia amylovora, is a devastating disease of apple and pear trees. Biological control methods have attracted much attention from researchers to manage plant diseases as they are eco-friendly and viable alternatives to synthetic pesticides. Herein, we isolated Streptomyces sp. JCK-8055 from the root of pepper and investigated its mechanisms of action against E. amylovora. Streptomyces sp. JCK-8055 produced aureothricin and thiolutin, which antagonistically affect E. amylovora...

Production of cello-oligosaccharides from corncob residue by degradation-synthesis reactions
In this study, two strategies were compared for their ability to transform CCR into cello-oligosaccharides (COS). The first strategy employed the use of endo-glucanases. Although selected endo-glucanases from GH9, GH12, GH45, and GH131 could release COS with degrees of polymerization from 2 to 4, the degrading efficiency was low. For the second strategy, first, CCR was efficiently depolymerized to glucose and cellobiose using the cellulase fromTrichoderma reesei. Then, using these simple sugars and sucrose as the starting materials, phosphorylases from different microorganisms were combined to generate COS to a level up to...

Beneath the parliamentary machinery of every state legislature is an intricate circuitry of unique customs and traditions. The North Carolina General Assembly (where I serve in the Senate) has a quirky assortment of the latter, including an annual tomato sandwich day, the ox-meter award (for long-winded debate), and “budget bingo”—lobbyists’ riff on the venerable game of chance. Rather than numbers chosen at random, this version banks on legislators’ use of hackneyed jargon while arguing for and against proposed spending plans. (Source: The Journal for Nurse Practitioners)
