“…Tripeptides like VPP and IPP generated from various protein sources such as milk and chia seeds have been proven to be potent ACE inhibitors (Daliri et al, 2017). In addition, bioactive peptides with antihypertensive properties have also been derived from several other plant sources such as potato, yam, rape seed, red seaweed, chickpea, lentil, and soy (Hayes and Bleakley, 2018). Reports suggest that besides animal and microbial proteases, plant proteases have also been proven to be efficient in producing ACE inhibitory peptides.…”

“…Peptides that are 20-46 amino acid residues long, less than 10 kDa in molecular weight, basic (lysine-or arginine-rich), and amphipathic are regarded as antimicrobial peptides (Sanchez and Vázquez, 2017). They can inhibit a large number of food spoilage microorganisms as well as pathogens and thus serve as a promising alternative to therapeutic agents (Hayes and Bleakley, 2018). Additionally, they are safer and ecofriendlier than synthetic antimicrobial agents.…”

Bioactive peptides are short and specific fragments of proteins with a wide range of biological activities that provide health benefits to the host. These natural peptides are safe and nontoxic and do not show any side effects. Nowadays, the production and characterization of bioactive peptides have been a key area of research as they show great potential as nutraceuticals and functional foods. Thus, bioactive peptides are considered next-generation therapeutic agents that can replace pharmaceutical products with profound adverse effects in the near future. So far, proteolytic hydrolysis has been used as the method of choice for the large-scale production of bioactive peptides. Studies have reported that peptides with specific characteristics can be generated using a particular type of protease. Microbial proteases are the predominantly used ones because of the ease in their production and purification. However, recently, plant proteases have gained a renewed interest as they offer diversity and better specificity compared with other proteases. This review highlights the potential of plant proteases for the production of bioactive peptides and also describes the benefits of bioactive peptides as nutraceuticals.

“…Cereals and yams contain certain types of bioactive peptides and amino acids which can promote human health and wellbeing [48]. The results of some studies revealed preventive action on cancers of cereal peptides such aslunasin for preventing skin cancers [49] and penta-peptide for preventing colon, breast, lung and liver cancers [50].…”

The chronic non-communicable diseases (NCD) are increasing throughout the populations and the burden of diseases is rising globally. Epidemiological evidences supports claim that intake of foods with certain health benefits and reducing the risk of NCDs are having positive correlation, therefore, a rise in demand for foods including phytochemicals can be observed. Cereals and yams are known to be rich sources of phytochemicals which can be utilized to produce functional food products having the potential of reducing the risk of chronic NCDs such as type 2 diabetes mellitus (T2DM), cardiovascular diseases (CVD) and certain types of cancers. In this review, the potentials of various cereals and yams that are being used as functional food products for human consumption to reduce the risk of NCD are being examined. The study further included a review on different phytochemicals in cereals and yams based functional food products and their bioactivity, potential of microencapsulation, cereal by products, influence of starch modification on functional food products, and capability of utilizing cereal by products in functional food industry.

“…They are responsible for maintaining a complex network of signalling molecules and other membrane proteins [ 22 ]. Thionins are antimicrobial peptides and have functions in seed germination and packaging of proteins for storage, and they act in signal transduction as secondary messengers [ 23 ]. WRKYs are part of a large family of transcription factors that are associated with responses to abiotic and biotic stresses and with various physiological processes [ 24 , 25 ].…”

Temporal expression of defence and susceptibility genes and tospovirus accumulation in capsicum chlorosis virus-infected capsicum

et al. 2022

Yolo Wonder (YW) and Warlock (W), two capsicum cultivars that are susceptible to capsicum chlorosis virus (CaCV), were compared in terms of symptom development, tospovirus accumulation, and host gene expression during the first 12 days post infection (dpi). Temporal expression of selected early CaCV-response genes was used to gain insights into plant-virus interactions and to identify potential targets for CaCV control. Symptoms developed faster in YW during the first seven days of infection, while systemic symptoms were similar in both cultivars at 10 and 12 dpi. CaCV accumulation was higher in YW at 7 dpi despite a lower titre at 3 dpi. At 12 dpi, virus accumulation was similar for both cultivars. Symptom development appears to be correlated to virus accumulation over time for both cultivars. Chalcone synthase (CHS), cytochrome P450 (CYP), and tetraspanin 8-like (TSP8) genes followed a similar expression pattern over time in both cultivars. The thionin gene showed increased expression in CaCV-infected plants at 12 dpi. The WRKY40 gene showed significant differential expression at all time points in YW, but only at 12 dpi in W. The strongest correlation of temporal gene expression and virus titre was seen for CYP, TSP8, thionin, and WRKY40. CHS and CYP may be involved in symptom development, and TSP8 may be involved in virus movement. CHS, CYP, and TSP8 may be good targets for future overexpression or silencing studies to clarify their functions during virus infection and, potentially, for control of CaCV in capsicum.
