“…Although the carbohydrate-binding properties of lectins are the most studied, some plant lectins can also interact with small molecules that are predominantly hydrophobic [4]. For instance, some plant lectins bind to porphyrins and phthalocyanines, which are photosensitizers used in clinical imaging for cancer cell detection with particular application in photodynamic therapy (PDT) [5,6]. Studies with lectins from the Diocleinae subtribe reported that they possess a hydrophobic site capable of interacting with hydrophobic molecules, such as 2-ptoluidinonaphthalene-6-sulfonate, hydrophobic sugar derivatives, phytohormones and auxin (e.g., indole-3-acetic acid or IAA, a naturally occurring auxin) [7].…”

“…These results might be due to a higher accumulation of osmolytes which is described as an indicator of plant's adaptive stress response (Islam et al, 2022). Carbohydrates play an active role in energy as well as principle criteria of cellular activity like cell division and growth in plants, where their concentration mostly depends on photosynthetic activity (Naithani et al, 2021). In the present experiment, a lower concentration of carbohydrates like TSC and sucrose under L3 and L4 treatments at 90 DAT indicates a stressful condition that might result from lower chlorophyll generation in plants (Figure 3).…”

Manipulation of growth and development of cannabis (Cannabis sativa L.) has received considerable interest by the scientific community due to its high value in medicinal and recreational use worldwide. This study was conducted to investigate the effects of LED spectral changes on reactive oxygen species (ROS) and cannabinoid accumulation by provoking growth, pigmentation, photosynthesis, and secondary metabolites production of cannabis grown in an indoor environment. After three weeks of vegetative growth under greenhouse condition, plants were further grown for 90 days in a plant factory treated with 4 LED light compositions with a canopy-level photosynthetic photon flux density (PPFD) of 300 µmol m−2 s−1 for 16 h. Photosynthetic pigments and photosynthetic rate were linearly increased up to 60 days and then sharply decreased which was found most prominent in L3: MB 240 (Red 85% + Blue 15%) and L4: PF 240 (Red 70% + Blue 30%) LED light compositions. A high concentration of H2O2 was also observed in L3 and L4 treatments which provoked lipid peroxidation in later growth stage. In addition, higher accumulation of cannabinoid was observed under L4 treatment in most cases. It is also evident that higher ROS created a cellular stress in plant as indicated by higher osmolyte synthesis and enzyme activity which initiate quick maturation along with higher cannabinoids accumulation in cannabis plant. Therefore, it can be concluded that ROS metabolism has a crucial role in morpho-physiological acclimation and cannabinoid accumulation in hemp plants. The findings of this study provide further insight on the use of LED light to maximize the production of cannabinoid.

“…Zm00001d013173 , which was annotated as a Phloem protein 2 ( PP2 ) like gene, encodes a PHLOEM PROTEIN 2-LIKE A10 (PP2-A10). Despite little information available on PP2-A10 in maize, its Arabidopsis ortholog AtPP2-A10 was identified as a member of the Arabidopsis lectin family gene ( Dinant et al, 2003 ; Naithani et al, 2021 ). Lectin family proteins possess at least one carbohydrate recognition domain (CRD), which enables reversible binding to carbohydrates.…”

Exploring the Developmental Progression of Endosperm Cavity Formation in Maize Grain and the Underlying Molecular Basis Using X-Ray Tomography and Genome Wide Association Study

Endosperm cavity (EC) in maize grain reduces yield and causes grain breakage during mechanical harvesting, hence representing a major problem in the maize industry. Despite this, little is known regarding the biological processes governing EC formation. Here, we attempted to address this issue by (i) determining the spatial and temporal progression of EC in a non-invasive manner and (ii) identifying candidate genes that may be linked to the formation of EC by using a genome wide association study (GWAS). Visualization and measurement using X-ray micro-computed tomography established that EC first appeared at the central starch endosperm at about 12 days after pollination (DAP) and became enlarged thereafter. GWAS-based screening of a panel of 299 inbred lines with a wide range of EC size identified nine candidate genes that showed significant association with EC formation. Most of the candidate genes exhibited a decrease at 12 DAP, coinciding with the timing of EC appearance. Among them, ZmMrp11 was annotated as a member encoding a multidrug resistance-associated protein that has been shown in other studies to sequestrate toxic metabolites from the cytosol to the vacuole, thereby detoxifying the cellular environment. This, together with the reduced expression of ZmMrp11 in maize grains from 12 DAP, prompted us to propose that the low expression of ZmMrp11 may block cellular detoxification in the maize endosperm cells, leading to cell death and ultimately the formation of EC.
