“…Under the FRL condition, this is typical only for PS2. Thus, the opinion available in the literature that RL as mono-chromatic light enhances the protective functions of plants, possibly through the activation of phytohormone signaling pathways, has been experimentally confirmed on cucumber leaves [28].…”

The photosynthetic activity of 28-day-old cucumber plants of the Kustovy variety formed under LED illumination with the predominance of red light (RL) or far red light (FRL) and infected with the fungus Fusarium oxisporum sp. (F.ox.) was studied. The predominance of RL or FRL contributed to an increase in the content of chlorophyll and carotenoids per dry leaf weight compared to the plants grown under white light (WL). In the infected plants grown under WL and RL regimes, an increase in the total content of chlorophyll and carotenoids was observed relative to healthy plants, and a decrease in the same parameters for FRL was noted. In healthy cucumber leaves grown under RL and FRL regimes, an increase in the activity of photosystem (PS)1 and PS2 in comparison with WL was observed. Infection of cucumber plants grown under WL did not cause any changes in the functional parameters of PS2 against the background of a slight reduction in PS1 complexes. Under RL and FRL regimes, a decrease in the photochemical activity of PS 1 and PS 2 in infected leaves was noted. The activity of ascorbate peroxidase - one of antioxidant enzymes in chloroplasts decreased in healthy cucumber leaves under RL and FRL compared to WL and increased in infected leaves compared to the healthy ones under all light regimes, especially strongly under RL. The results obtained demonstrate different response mechanisms for cucumber chloroplasts to the infection with a fungal pathogen, depending on the light conditions of growing.

“…All these results demonstrated that MAPKKK/MAPKK/MAPK-WRKY-CML/CDPK might indicate a new complex network in soybean for defense against SMV infection. By summarizing the PPI analysis in this study and combining it with previous reviews on the role of circadian rhythm in plant immunity ( Hua, 2013 ; Wang et al, 2021 ), we drew a model diagram of soybean resistance response to SMV ( Figure 8B ).…”

As a high-value oilseed crop, soybean [Glycine max (L.) Merr.] is limited by various biotic stresses during its growth and development. Soybean mosaic virus (SMV) is a devastating viral infection of soybean that primarily affects young leaves and causes significant production and economic losses; however, the synergistic molecular mechanisms underlying the soybean response to SMV are largely unknown. Therefore, we performed RNA sequencing on SMV-infected resistant and susceptible soybean lines to determine the molecular mechanism of resistance to SMV. When the clean reads were aligned to the G. max reference genome, a total of 36,260 genes were identified as expressed genes and used for further research. Most of the differentially expressed genes (DEGs) associated with resistance were found to be enriched in plant hormone signal transduction and circadian rhythm according to Kyoto Encyclopedia of Genes and Genomes analysis. In addition to salicylic acid and jasmonic acid, which are well known in plant disease resistance, abscisic acid, indole-3-acetic acid, and cytokinin are also involved in the immune response to SMV in soybean. Most of the Ca2+ signaling related DEGs enriched in plant-pathogen interaction negatively influence SMV resistance. Furthermore, the MAPK cascade was involved in either resistant or susceptible responses to SMV, depending on different downstream proteins. The phytochrome interacting factor-cryptochrome-R protein module and the MEKK3/MKK9/MPK7-WRKY33-CML/CDPK module were found to play essential roles in soybean response to SMV based on protein-protein interaction prediction. Our findings provide general insights into the molecular regulatory networks associated with soybean response to SMV and have the potential to improve legume resistance to viral infection.

“…The G-box is a ubiquitous light regulatory element in many of the promoters [56] and is highly represented lightresponsive cis-element (279) among the EcNBLRRs promoters, followed by Box-4 (90), GT-1 (62) motif etc. Several studies have shown the essential roles of a particular spectrum of light in promoting plant defence against various pathogen infections [57]. For instance, the red-light spectrum enhances the plants' resistance to various pests and pathogens [58]; however, the detailed molecular basis still needs to be elucidated.…”

Background The nucleotide-binding site–leucine-rich repeat (NBLRR) genes significantly regulate defences against various phytopathogens. The genome-wide identification and analysis of NBLRR genes have been performed in several species. However, the evolution, structure, expression of NBLRRs and functional response to Magnaporthe grisea are not known in Finger millet (Eleusine coracana L.). Results The genome-wide scanning of the Finger millet genome resulted in 116 NBLRR genes named EcNBLRRsaccording to their chromosomal positions in ascending order. The phylogenetic analysis revealed divergence of NBLRRs as per the speciation of target species. The whole-genome duplications shaped the expansion of the NBLRR family in the finger millet genome, and purifying selection (Ka/Ks<1) shaped expansions of EcNBLRR paralog and ortholog pairs. The maximum orthology and syntenic association of NBLRRs was observed between Finger millet and Brachypodium distachyon over Finger millet and Arabidopsis thaliana. The promoter sequence analysis showed various stress- and phytohormone-responsive cis-acting elements besides growth and development, indicating their role in disease defence and regulatory mechanisms. The functional analysis of 22 EcNBLRRsin the genotypes showing contrasting responses to Magnaporthe grisea infection revealed the role of target EcNBLRRs in finger millet- Magnaporthe grisea interactions at early (EcNBLRR83; EcNBLRR55; EcNBLRR30 and EcNBLRR32) and late (EcNBLRR76; EcNBLRR45; EcNBLRR26; EcNBLRR23 and EcNBLRR21) stage of infections. Conclusion The identification and functional analysis of EcNBLRRs showed the role of EcNBLRR genes in assigning blast resistance in finger millet. These results pave the foundation for in-depth and targeted functional analysis of EcNBLRRs through genome editing and transgenic approaches.
