- Inhibition of cell multiplication In the context of the present patent application, said term should be understood as the inhibition of the multiplication of any types or lines of mammalian, plant or microorganism cells, and the cells can be in any of the stages of cell division, cells may or may not be synchronized in the cell cycle. Inhibiting cell multiplication of cells presents, in the context of the present patent application, the meaning of interrupting the process of cell division, resulting or not in cell death.
- Pests or contamination of plants or food In the context of the present patent application, pests or contamination of plants or foods are considered to be those biological agents that contaminate plants or foods, that are related to their rotting and/or that cause damage to the quality or shelf life of such products. .
- microbial contaminations that lead to rot, those that form toxins and those that alter.
- examples include, but are not limited to, P. nicotiana and P. idaei, Botrytis cinerea, Colletotrichum spp. Rhizopus stolonifer, S. sclerotiorum, Pestalotia longisetula Rhizoctonia sp., Geotrichum sp., Gnomon ia comari, Pilidium concavum related, among others, to strawberry rot, Xylella fastidiosa in coffee and orange groves, fungi associated with stock, transport and/or processing medicinal cannabis.
- pep5 or “Pep5”.
- the term is to be understood as the peptide represented by SEQ ID NO: 1, the amino acid sequence being WELVVLGKL.
- cpp in the context of the present patent application, the term is to be understood as being a peptide tail, which can be represented by SEQ ID NO: 2, the amino acid sequence being YGRKKRRQRRR.
- the term is to be understood as the peptide represented by SEQ ID NO: 1 linked to the peptide tail represented by the sequence SEQ ID NO: 2.
- AN-pep5-cpp In the context of the present patent application, the term is to be understood as the peptide represented by SEQ ID NO: 1 but without the last amino acid of the N-terminal portion, and linked to the peptide tail represented by the sequence SEQ ID NO: 2.
- AC-pepS-coo In the context of the present patent application, the term is to be understood as the peptide represented by SEQ ID NO: 1 but without the last amino acid of the C-terminal portion, and linked to the peptide tail represented by the sequence SEQ ID NO: 2.
- SEQ ID NO: 9 An example is SEQ ID NO: 9.
- SEQ ID NOs: 4 to 14 are considered within the inventive concept of the present invention due to the small changes in the amino acid sequence with respect to SEQ ID NO: 1 and SEQ ID NO: 9, both effectively tested in the present report.
- Example 1 Use of the peptide for the preparation of a plant or food preservation additive.
- SEQ ID NO: 3 The peptide of SEQ ID NO: 3, comprising pep5 (SEQ ID NO: 1 ) and cell penetrating peptide (SEQ ID NO: 2), was prepared in 100pM solution in water, for direct topical use on the food to be preserved.
- Figure 1 shows the visual results of an experiment of application of 100pM of the preservative peptide (SEQ ID NO: 3) or water (control) on fresh strawberries, all from the same batch and commercial product packaging.
- the results of groups of 10 strawberries in each condition (test and control) are shown at 0, 12, 24, 36, 48 and 60h, respectively in A, B, C, D, E and F.
- Figure 2 shows the time in hours (abscissa) and the percentage of spoiled fruits (ordered) after application of 100pM of the preservative peptide (SEQ ID NO: 3) or water on fresh strawberries.
- Example 3 Tests of the additive comprising the peptide in the preservation of strawberries against rot.
- FIG. 3 shows the visual results of an experiment of application of the additive of the invention with 100pM of the preservative peptide (SEQ ID NO: 3) in water, or only water as a control on 8 fresh strawberries in each group, all of them from the same batch and same packaging of commercial product. Representative results of strawberries in each condition (test and control) are shown at Oh, 24h, 48h and 5 days, respectively in A, B, C and D.
- Example 4 Tests of the preservative additive comprising the peptide in the modulation of the germination rate of bean seeds.
- Figure 4 shows the visual results of an experiment of application of a single dose of 100pM (in water) of the preservative peptide (Ktut, SEQ ID NO: 3) or water (control) on bean seeds, all of which same batch and same package of commercial product and kept at temperature ambient (28°C).
- the results of germination of groups of 14 seeds in wet cotton are shown in each condition (control and test) at 0, 3 and 4 days, respectively in A, B and C.
- the images show that there were differences in the germination pattern of the beans .
- Figure 5 shows the time in days (abscissa) and the number of bean seeds that will germinate (ordered) after application of 100pM of the preservative peptide (Ktut, SEQ ID NO: 3) as indicated in Figure 4.
- results show substantial modulation of the metabolic state of the shoots or seedlings, as well as the delay in the process of seed germination when the said additive is applied.
- the invention has therefore proved to be useful to modulate germination, adjust planting or germination time, among other agronomic or botanical advantages.
- Example 5 Tests of the additive comprising the preservative peptide in the preservation of post-harvest flowers.
- the chosen flowers were the rose (Rosa-rubra) and the gerbera (Gerbera).
- the species of the genus Rosa are among the most cultivated ornamental flowers in the world.
- the species of the genus Gerbera are used as an experimental organism in studies of flowering and meristematic development of the flower, and because they contain natural derivatives of coumarin, they are flowers of phytochemical interest and biological control.
- the peptide of SEQ ID NO: 15 was used, which comprises the peptide of SEQ ID NO: 9 and the peptide of SEQ ID NO: 2.
- Figure 6 shows the visual results of an experiment of application of a single dose of 100pM (in water) of the preservative peptide (SEQ ID NO: 15) or water (control) on two types of flowers, all of the same lot and same day of acquisition, kept at room temperature (28°C).
- Four flowers were used in each container, the stems being kept submerged with at least 5 cm of the respective liquid during the test period.
- Aluminum foil was used around the container where the stems were submerged, to protect from light. Photographic results of flowers kept in each condition (control and test) at 0, 3 and 6 days are shown.
- A) and E) images of roses are shown, respectively on days 0, 3 and 6, the left roses kept in H2O and the right roses in the preservative peptide as indicated above.
- B) and F) are shown images of gerberas, respectively on days 0, 3 and 6, the gerberas on the left kept in H2O and the gerberas on the right in the preservative peptide as indicated above.
- the images clearly show that there were significant differences in the pattern of preservation of the flowers kept in the preservative.
