Fig. 1. Multiple sequence alignment of the amino acid sequence of PP2 proteins from Cucurbitaceae species as well as from A. thaliana and A. graveolens. Sequences of A. graveolens (CBC70481.1), A. thaliana (CAB78986.1), Coccinia indica agglutinin CIA17 (P0DSP5.1), Cucumis sativus (KAE8649724.1), Cucumis melo (AAM74924.1), Luffa acutangula (C0HJV2.1), Cucurbita argyrosperma (CBC70491.1), Cucurbita arg. sororia (AAM82558.1), Cucurbita moschata (AAF74345.1), Cucurbita pepo (023518987.1), Cucurbita maxima (AAA33117.1), Cucurbita digitata (AAM82559.1) were taken from NCBI gene bank. Multiple sequence alignment was performed using Clustal Omega (https://www.ebi.ac.uk/Tools/msa/clustalo/). The highly conserved amino acids 100-Leu-Ile-Glu-Val-Ser-Trp-105 and 199-Trp- Lys-200, which are important for chitooligosaccharide binding are shown in boxes. The residue numbers correspond to the primary structure of PPL.
Fig. 6 in Cucurbitaceae phloem exudate lectins: Purification, molecular characterization and carbohydrate binding characteristics
Fig. 6. Interaction of chitohexaose with the carbohydrate binding cleft of PPL, showing the amino acid residues involved in carbohydrate binding. The binding site was divided into three subsites as indicated by arrows: subsite 1 (Leu-100, Glu-102), subsite 2 (Ile-101, Ser-104, Trp-105) and subsite 3 (Trp-199, Lys- 200). Only three GlcNAc residues from the non-reducing end of chitohexaose are seen to interact with the binding cleft. GlcNAc residues at the reducing end interact with another PPL monomer (shown in the circle at the top left corner). Reproduced from Bobbili et al. (2014). Copyright (2014) Elsevier.

Fig. 6 in Protochlorophylls in Cucurbitaceae - Distribution, biosynthesis and phylogeny
Fig. 6. The content of Chl a, Pchl-GG and Chl-GG in the primary leaves of 11- day-old etiolated Cucurbita maxima 'Bambino' seedlings during illumination. The data are means ± SE, n = 3–4. The pigments were extracted and analyzed using HPLC as described in the Experimental section.
Fig. 7 in Protochlorophylls in Cucurbitaceae - Distribution, biosynthesis and phylogeny
Fig. 7. (a) The unrooted phylogenetic tree of the nucleotide sequences of the chlorophyll synthase genes. The tree shows topology only. Seven different clades are distinguished. The subtree representing Clade 7 is shown with the branches occupied by two isoforms of Cucurbita pepo, C. maxima and C. moschata: C1 and C2. (b) Alignment of the chlorophyll synthase sequences of Cucurbita isoform C1, C2 and the remaining sequences of the Clade 7. The size of the letters is scaled proportionally to the numbers of the sequences that have a given amino acid in the given position. The letters are arbitrarily colour-coded to highlight similarities and differences: grey - the indicated residue is found in at least 80% of the sequences in this position in every group; green – conserved residues unique to only one group of sequences; black – variable residues, less than 80% of sequences are present in this position. The residues previously shown to play a catalytic role are highlighted in red. The position of the transmembrane helices suggested by the Uniprot database is highlighted in blue, while that predicted by the homology modelling is marked with a darkblue rectangle. (c) A 3D model of chlorophyll synthase based on the primary sequence of C. pepo subsp. pepo (NCBI: XP 023543340.1). (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)
Fig. 4 in Protochlorophylls in Cucurbitaceae - Distribution, biosynthesis and phylogeny
Fig. 4. The content of Chl-GG (A), Chl a (B) and Pchl-GG (C) in the primary leaves of 11-day-old etiolated Cucurbita pepo 'Miranda' seedlings during illumination. In the case of ALA-treated plants, the 11-day-old seedlings were incubated for additional 3 days in 10 mM ALA solution in the dark before illumination. The data are means ± SE, n = 3–4. FW = fresh weight. The pigments were extracted and analyzed using HPLC as described in the Experimental section.
