We have identified a limited number of proteins secreted into the nectar of tobacco plants. Nectarin I is the most highly expressed nectar protein and has a monomer molecular mass of 29 kDa. The other major nectar proteins are expressed at lower levels and have monomer molecular masses of 41, 54, and 65 kDa respectively. Nectarin I was purified and antiserum was raised against the protein. Under nondenaturing conditions, Nectarin I has an apparent molecular mass of >120 kDa. The expression of… 

Identification and characterization of proteins expressed in the nectar of ornamental tobacco

The hypothesis of this work is that nectar proteins are secreted into nectar to maintain an axenic state and to protect the developing gynoecium from microbial attack and oxidative damage.

Tobacco Nectarin III is a Bifunctional Enzyme with Monodehydroascorbate Reductase and Carbonic Anhydrase Activities

RT-PCR based expression analyses demonstrated that NEC3 transcript is expressed throughout nectary development as well as in other floral organs, and a proposed function in the maintenance of pH and oxidative balance in nectar is discussed.

Nectarin IV, a Potent Endoglucanase Inhibitor Secreted into the Nectar of Ornamental Tobacco Plants. Isolation, Cloning, and Characterization12

The patterns of expression of the NEC4 protein indicate that, while expressed in nectar at anthesis, it is most strongly expressed in the nectary gland after fertilization, indicating that inhibition of fungal cell wall-degrading enzymes may be more important after fertilizing than before.

The nectary-specific pattern of expression of the tobacco Nectarin I promoter is regulated by multiple promoter elements†

Analysis in transgenic plants revealed that the nectary-specific expression is the result of multiple promoter elements and suggests that nectar secretion and flower opening may be coordinately regulated.

Proteomics and post-secretory content adjustment of Nicotiana tabacum nectar

After secretion, the ratio of hexose to sucrose substantially increased for in vivo nectar, but no sugar composition changes were detected in vitro, implying that sucrose hydrolysis in vivo might be done by fixed apoplastic invertase.

The major nectar protein of Brassica rapa is a non-specific lipid transfer protein, BrLTP2.1, with strong antifungal activity

Results suggest that BrLTP2.1 may function to prevent microbial growth in nectars, and has relatively high sequence similarity to non-specific lipid-transfer proteins with known functions in plant defense.

Identification, cloning and characterization of a GDSL lipase secreted into the nectar of Jacaranda mimosifolia

The presence of at least eight distinct proteins secreted into the floral nectar of the tropical tree Jacaranda mimosifolia (Bignoniaceae) is reported and potential functions of JNP1 in relation to pollinator attraction and prevention of microbial growth within nectar are briefly discussed.

Acidic α-galactosidase is the most abundant nectarin in floral nectar of common tobacco (Nicotiana tabacum).

Compared with 27 other melliferous plant species from different families, CT floral nectar demonstrated the highest α-Gal activity, which is inhibited by d-galactose, suggesting that NTα-Gal induces cell-wall surface restructuring during the initial stages of fruit development.

Petunia nectar proteins have ribonuclease activity

Analysis of amino acid patterns suggest that these proteins are an intermediate between S- and S-like RNases, and support the hypothesis that S-RNases evolved from defence RNases expressed in floral parts.

A major function of the tobacco floral nectary is defense against microbial attack

The characterized major nectar protein from ornamental tobacco as a superoxide dismutase that functions to generate high levels of hydrogen peroxide in nectar indicates that the floral nectary gland can have specific functions in plant defense.



Germin isoforms are discrete temporal markers of wheat development. Pseudogermin is a uniquely thermostable water-soluble oligomeric protein in ungerminated embryos and like germin in germinated embryos, it is incorporated into cell walls.

It seems that germin may act at the level of the apoplast and that pseudogermin may subsume the role of germin at low water potentials during embryogenesis, as are some peculiarities of amino-acid sequence that suggest a possible relation between germin and a proton-specific ion pump: gastric ATPase.

Amino-acids in Nectar and their Evolutionary Significance

Unusual feeding-behaviour is shown by butterflies of the genus Heliconius which collect pollen, steep it in nectar, and subsequently ingest the amino-acids that diffuse from the grains.

Germin, a protein marker of early plant development, is an oxalate oxidase.

Three Glycosylated Polypeptides Secreted by Several Embryogenic Cell Cultures of Pine Show Highly Specific Serological Affinity to Antibodies Directed against the Wheat Germin Apoprotein Monomer

Investigation of embryogenic tissues of Pinus caribaea Morelet var hondurensis indicated that the polypeptide GP111 plus two others with similar relative molecular mass values are present in embryogenic cell lines but not in nonembryogenic ones.

cDNA sequence, genomic organization and differential expression of three Arabidopsis genes for germin/oxalate oxidase-like proteins

CDNA clones for three genes encoding germin-like proteins from Arabidopsis thaliana cDNA libraries were further characterized and Sequence analysis and secondary structure predictions of the proteins encoded by these cDNAs showed that they possess all the characteristic features of members of the Germin family and of the germin/seed globulins/sucrose binding protein superfamily.

Arabidopsis thaliana contains a large family of germin-like proteins: characterization of cDNA and genomic sequences encoding 12 unique family members

This analysis demonstrates that the Arabidopsis genome contains a gene family with at least 12 GLP genes, and Comparisons with other known germins and germin-like proteins indicate that theseArabidopsis GLP subfamilies are unique from wheat germin.

Characterization and sequencing of cDNA clone encoding the phloem protein PP2 of Cucurbita pepo

Southern blot showed that PP2 is encoded by a gene family with a relatively large number of members (estimated as 7–15 per haploid genome) and suggests that the N-terminus of the protein is a blocked methionine residue which is cleaved off by CNBr.

Regulated expression of a wheat germin gene in tobacco: oxalate oxidase activity and apoplastic localization of the heterologous protein

The biochemical characteristics of wheat germin were conserved in a transgenic host: the OxO activity was present under the form of a doublet co-migrating with germin G and G′ isoforms despite the fact that wheat cell wall substantially differs from tobacco cell wall.

Purification and partial characterization of a glycoprotein from pea (Pisum sativum) with receptor activity for rhicadhesin, an attachment protein of Rhizobiaceae

It is speculated that the plant receptor for rhicadhesin is a glycoprotein containing an R-G-D attachment site, which was reported to inhibit attachment of A. tumefaciens to carrot cells in the course of this research project.

Regulation of a Sulfur-Controlled Protease in Neurospora crassa

Wild-type Neurospora crassa produces and secretes extracellular protease(s) when grown on a medium containing a protein as its principle sulfur source, and synthetic activity is induced by proteins, and to a lesser extent by large-molecular-weight polyamino acids, but not at all by small peptides or amino acid mixtures.
