“…In South-east countries like South Korea, China, Japan and India, many traditional medications are used to treat SARS-CoV-2, but the efficiency of the compounds are limiting and molecular mechanisms are also unclear. Plants possess amazing defense competence towards diseases (Panigrahi and Satapathy 2021 ; Panigrahi et al 2021 ). The phytomolecules are also known as the bioactive compounds which have the tendency to modify the cellular physiological processes.…”

The emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) or 2019 Novel Coronavirus (2019-nCoV) has put the entire globe into unrest, primarily due to unavailability of specific drug against the viral proteins. In the last two decades the world has withstood many contagious disease crashes. SARS-CoV-2 has put the world and the mankind in danger. It is spreading unstoppably all over the world. The virus is evolving and thus the pathogenicity of SARS-CoV-2 strains has been different and making it difficult to develop a broad-spectrum anti-viral molecule that would be effective against all the SARS-CoV-2 variants. This imperative situation demands development of molecules for effective treatment against SARS-CoV-2. The phytomolecules or the bioactive molecules of plants could be a great alternative to combat SARS-CoV-2. The bioactive molecules with their antiviral properties and the secondary metabolites may effectively deactivate the functioning of viral proteins. The structural configuration of 2019-nCoV proteins and genomic information are available, thus contributing immensely for fast molecular docking studies and hence, enables screening of numerous accessible phytomolecules. In the current study, we have essentially highlighted common phytomolecules against the known viral proteins and described the mode of action of few plant-derived molecules which have the potential to suppress the activity of the viral proteins.

“…Defense-related (DR) genes are a kind of genes that can be rapidly induced by pathogen infection and elicitors (Zhang et al 2019;Panigrahi et al 2021). These genes are regarded as important resources for disease resistance, especially for those diseases lacking major resistant genes.…”

Banded leaf and sheath blight (BLSB) caused by the necrotrophic fungus Rhizoctonia solani is a devasting disease on maize worldwide, especially in China and Southeast Asia. To explore the maize defense mechanisms against R. solani expansion, the expression profile of maize infected by low virulence strain (LVS) and high virulence strain (HVS) of R. solani for 3 and 5 d was analyzed by RNA-sequencing. A total of 3015 and 1628 differentially expressed genes (DEGs) were identified under LVS and HVS infection, respectively. Meanwhile, these DEGs were classified by Gene Ontology (GO) for biological process analysis. Only defense-related GO terms were commonly enriched in LVS- and HVS-regulated genes. Furthermore, a core set of 388 up-regulated genes that are involved in maize response to R. solani infection were identified. Additionally, among the core genes, overexpressing ZmNAC41 and ZmBAK1 enhanced rice resistance to R. solani. Taken together, our study provides additional insight into maize defense mechanisms against R. solani, and the core genes identified in this study will be important resources for improving BLSB resistance in the future.

“…It is intriguing to reveal the role of EJC when the plants are grown at different exposure to light. Plants invariably alter the key molecular processes when exposed to different stress conditions (13)(14)(15). Since, EJC is well involved in various physiological pathways; it would be significant to reveal the role of EJC when plants are grown at varied growth conditions (16,17).…”

Exon junction complexes (EJCs) associate with mRNAs, mediate the pre-mRNA splicing and eventually gets displaced by ribosomes during the initial phase of translation. EJCs are involved in several critical physiological pathways. The functional nature of EJCs and the underlying molecular mechanism(s) still needs to be elucidated particularly in case of plants. Here, we report that the putative core protein factors of the EJC differentially express under short-day and long-day conditions. Since, plants are constantly exposed to biotic and abiotic factor(s), it would be significant to see how the EJCs respond to different stress inducing conditions. The protein levels of EJC core proteins under short-day conditions were 1.25 times higher relative to the protein levels under long-day conditions. Similar results were observed for the mRNA transcripts of the EJC core protein factors. These results signify that under short-day conditions, the EJC proteins are more activated and might be involved in few events which are yet to be revealed.
