“…[1][2][3][4][5] Unlike their animal counterparts, plant LTPs typically have broad substrate specificity and are also named nonspecific LTPs. Their affinity for lipids is presumed to be crucial for their biological function, but in vivo substrates remain largely unknown.…”

“…16 This function may be related to their antimicrobial activity, initially observed in radish extracts 17 and later determined in several isoforms isolated from monocots as well as dicots. 1,18 Besides, the existence of a plant LTP sub-family involved in lipid signaling has been proposed. 19 The Arabidopsis LTP named DIR1 is implicated in defense signaling 20 and N5 from Medicago truncata is involved in the symbiotic interaction with rhizobia, probably regulating the competence of epidermal cells for rhizobial infection.…”

“…Regarding genes involved in transport metabolism, different lipid transfer proteins as well as water channel proteins (ABC transporter and plasma membrane integral protein -PIP www.intechopen.com protein) were induced by tolerant SP83-5073 plants in response to stress. Lipid transfer proteins contain chemical characteristics to bind and transport hydrophobic molecules and thus associated with enhanced cell wall extension in tobacco (Carvalho & Gomes, 2007;Nieuwland et al, 2009). It is supposed that these proteins induce the transfer of lipids through the extracellular matrix due to the increased accumulation of cuticular wax observed in tobacco leaves in response to drought events (Cameron et al, 2006).…”

“…Plant lipid transfer proteins are small basic proteins, which are able to bind hydrophobic compounds in vitro and encoded by large multigene families (Carvalho and Gomes 2007;Kader et al 2007;Edstam et al 2011). LTPs are involved in key processes in plant physiology, such as cell wall organization, stabilization of membranes, signal transduction, plant growth and development (sexual reproduction, seed development and germination) (Nielsen et al 1996;Maldonado et al 2002).…”

Damping-off disease in pine seedling, caused by fungi and oomycetes (Fusarium, Alternaria, Botrytis, Phytophthora) and other species, is one of the most dangerous diseases in conifer nurseries and greenhouses worldwide. Alternaria alternata is a necrotrophic pathogen, which causes early blight in higher plants and results in massive economic losses in agro-industry as well as in forestry. Pine seedlings that lack strong lignificated and suberized cell walls at early stages of their growth are vulnerable to damping-off disease. So, triggering the synthesis of antimicrobial compounds, such as phytoalexins, anticipins and pathogenesis-related (PR) proteins, is the main defense strategy to confine pathogens at early stages of pine ontogenesis. Defensins and lipid transfer proteins are members of two PR-protein families (PR-12 and PR-14 respectively) and possess antimicrobial activities in vitro through contact toxicity, and the involvement in defense signalling. In this work, we describe the changes in the expression levels of four defensin genes and lipid transfer protein in Scots pine seedlings infected with A. alternata. The expression levels of PsDef1 and PsDef2 increased at 48 h.p.i. (hours post inoculation). The levels of PsDef4 transcripts have increased after 6 and 24 hours. Notably, at 48 h.p.i., the level of PsDef4 transcripts was decreased by 1.2 times compared to control. The level of PsDef3 transcripts was reduced at all three time points. On the other hand, the level of PsLTP1 transcripts increased at 6 h and 48 h.p.i.; while at 24 h.p.i., it decreased by 20% when compared to the control sample. Our results suggest that defensins and lipid transfer protein are involved in the defense response of young Scots pine to necrotrophic pathogen. Thus, those genes can be used as the molecular markers in forestry selection and development of the ecologically friendly remedies for coniferous seedlings cultivation in greenhouses and nurseries.
