Special Issue Information

Dear Colleagues,

Nowadays, increasing world population and ever more pressing climate change pose major challenges for the future of the human species. The choice of plant varieties for food production, both for humans and animals, and the possibility of maintaining genetic diversity in natural environments, should be a major goal of modern scientific and technological research efforts. Understanding both molecular and non-molecular mechanisms of how plants are affected by ongoing climate change, and discovering new ways to increase plant productivity, is an important step toward new frontiers of growth and technological advancement in modern society. Authors are cordially invited to participate with original articles or reviews on this broad topic. The collected data will certainly add to the understanding of these issues that increasingly burden modern society.

Members of the phloem protein 16 (PP16) gene family are induced by elicitors in rice and the corresponding proteins from cucurbits, which display RNA binding and intercellular transport activities, are accumulated in phloem sap. These proteins facilitate the movement of protein complexes through the phloem translocation flow and may be involved in the response to water deficit, among other functions. However, there is scant information regarding their function in other plants, including the identification of paralog genes in non-vascular plants and chlorophytes. In the present work, an evolutionary and structural analysis of the PP16 family in green plants (Viridiplantae) was carried out. Data mining in different databases indicated that PP16 likely originated from a larger gene present in an ancestral lineage that gave rise to chlorophytes and multicellular plants. This gene encodes a protein related to synaptotagmin, which is involved in vesicular transport in animal systems, although other members of this family play a role in lipid turnover in endomembranes and organelles. These proteins contain a membrane-binding C2 domain shared with PP16 proteins in vascular plants. In silico analysis of the predicted structure of the PP16 protein family identified several β-sheets, one α-helix, and intrinsically disordered regions. PP16 may have been originally involved in vesicular trafficking and/or membrane maintenance but specialized in long-distance signaling during the emergence of the plant vascular system. Full article
