“…Although the result suggest that VabHLH137 is involved in defense-induced PA biosynthesis, it did not indicate whether VabHLH137 specifically regulates PA biosynthesis in response to C. gloeosporioides infection. Anthocyanin accumulation represents another common response of plants to multiple biotic and abiotic stresses [ 37 , 61 ]. Here, VabHLH137 overexpression boosted anthocyanin accumulation in the grape calli, while the anthocyanin content was too low to be measured in the infected grape berries at the EL33 stage.…”

Proanthocyanidins (PAs) and anthocyanins are involved in the response of plants to various environmental stresses. However, the mechanism behind defense-induced PA biosynthetic regulation is still not completely elucidated, also in grapevine. This study performed a transcriptome sequencing analysis of grape berries infected with Colletotrichum gloeosporioides to highlight the induction of the VabHLH137 factor from the basic helix-loop-helix (bHLH) XII subfamily by the fungus, which appeared to be significantly co-expressed with PA-related genes. The functional analysis of VabHLH137 overexpression and knockdown in transgenic grape calli showed that it positively regulated PA and anthocyanin biosynthesis. Moreover, VabHLH137 overexpression in the grape calli significantly increased resistance to C. gloeosporioides. A yeast one-hybrid and electrophoretic mobility shift assay revealed that VabHLH137 directly bound to the VaLAR2 promoter, enhancing its activity and interacting with VaMYBPAR, a transcriptional activator of PA biosynthesis. Furthermore, transient experiments showed that although the VabHLH137+VaMYBPAR complex activated VaLAR2 expression, although it failed to further enhance VaLAR2 expression compared to VaMYBPAR alone. The findings indicated that VabHLH137 enhanced PA biosynthesis by activating of VaLAR2 expression, providing new insight into the transcriptional regulation of defense-induced PA biosynthesis in grapevine.

“…They provide a well-known physiological function to attract pollinators and seed dispersers ( Chaves-Silva et al, 2018 ). Apart from their colorant properties, anthocyanins are reported to be induced under diverse biotic and abiotic stresses, including UV radiation, cold and drought stress, and bacterial and fungal pathogen infection, which suggests a role in cell stress-coping mechanisms ( Sperdouli and Moustakas, 2012 ; Sivankalyani et al, 2016 ; Bæksted Holme et al, 2021 ; Lin et al, 2021 ). Moreover, anthocyanins also play an important role in human health to prevent different chronic pathologies ( Li et al, 2021 ).…”

Barley grains are a rich source of compounds, such as resistant starch, beta-glucans and anthocyanins, that can be explored in order to develop various products to support human health, while lignocellulose in straw can be optimised for feed in husbandry, bioconversion into bioethanol or as a starting material for new compounds. Existing natural variations of these compounds can be used to breed improved cultivars or integrated with a large number of mutant lines. The technical demands can be in opposition depending on barley’s end use as feed or food or as a source of biofuel. For example beta-glucans are beneficial in human diets but can lead to issues in brewing and poultry feed. Barley breeders have taken action to integrate new technologies, such as induced mutations, transgenics, marker-assisted selection, genomic selection, site-directed mutagenesis and lastly machine learning, in order to improve quality traits. Although only a limited number of cultivars with new quality traits have so far reached the market, research has provided valuable knowledge and inspiration for future design and a combination of methodologies to achieve the desired traits. The changes in climate is expected to affect the quality of the harvested grain and it is already a challenge to mitigate the unpredictable seasonal and annual variations in temperature and precipitation under elevated [CO2] by breeding. This paper presents the mutants and encoded proteins, with a particular focus on anthocyanins and lignocellulose, that have been identified and characterised in detail and can provide inspiration for continued breeding to achieve desired grain and straw qualities.

“…In addition, anthocyanins are involved in regulating ROS-induced signaling responding to environmental cues [28][29][30]. Anthocyanins may be regulators of the ROS-signaling network due to their ability to interact with protein and to enhance the activity of protein through the ROS reaction [20,31,32]. However, the functional roles of flavonoids in plants remain indistinct not only for their numerous varieties, but also for their different influences in different plant species.…”

Anthocyanins are natural pigments with antioxidant effects that exist in various fruits and vegetables. The accumulation of anthocyanins is induced by environmental signals and regulated by transcription factors in plants. Numerous evidence has indicated that among the environmental factors, light is one of the most signal regulatory factors involved in the anthocyanin biosynthesis pathway. However, the signal transduction of light and molecular regulation of anthocyanin synthesis remains to be explored. Here, we focus on the research progress of signal transduction factors for positive and negative regulation in light-dependent and light-independent anthocyanin biosynthesis. In particular, we will discuss light-induced regulatory pathways and related specific regulators of anthocyanin biosynthesis in plants. In addition, an integrated regulatory network of anthocyanin biosynthesis controlled by transcription factors is discussed based on the significant progress.
