Plant non-specific lipid transfer proteins (nsLTPs) are a group of small, secreted proteins that can reversibly bind and transport hydrophobic molecules. NsLTPs play an important role in plant development and resistance to stress. To date, little is known about the nsLTP family in cabbage. In this study, a total of 89 nsLTP genes were identified via comprehensive research on the cabbage genome. These cabbage nsLTPs were classified into six types (1, 2, C, D, E and G). The gene structure, physical and chemical characteristics, homology, conserved motifs, subcellular localization, tertiary structure and phylogeny of the cabbage nsLTPs were comprehensively investigated. Spatial expression analysis revealed that most of the identified nsLTP genes were positively expressed in cabbage, and many of them exhibited patterns of differential and tissue-specific expression. The expression patterns of the nsLTP genes in response to biotic and abiotic stresses were also investigated. Numerous nsLTP genes in cabbage were found to be related to the resistance to stress. Moreover, the expression patterns of some nsLTP paralogs in cabbage showed evident divergence. This study promotes the understanding of nsLTPs characteristics in cabbage and lays the foundation for further functional studies investigating cabbage nsLTPs.

APYRASEs, which directly regulated the intra- and extra-cellular ATP homeostasis, plays a pivotal role in the regulation of the adaptations to various stresses in mammals, bacteria and plants. In the present study, we identified and characterized the wheat APYRASE family members at the genomic level. The results showed that a total of eight APY homologs with conserved ACR domains were identified. The wheat APYs were further analyzed bioinformatically of their sequence alignment, phylogenetic relations and conserved motifs. Although they share highly conserved secondary structure and tertiary structure, the wheat APYs could be mainly categorized into three groups, according to the phylogenetic and structural analysis. Further, these APYs exhibited similar expression patterns in the root and shoot, among which TaAPY3-1 and TaAPY3-3 had the highest expression level. The time-course expression patterns of the eight APYs in the wheat seedlings in response to the biotic stress and abiotic stress were also investigated. TaAPY3-2, TaAPY3-3, and TaAPY6 exhibited strong sensitivity to all kinds of stresses in the leaves. Some APYs showed specific expression responses, such as TaAPY6 to the heavy metal stress, and TaAPY7 to the heat and salt stress. These results suggested that the stress-inducible APYs could have potential roles in the regulation of the adaptation to the environmental stresses. Moreover, the catalytic activity of TaAPY3-1 was further analyzed in the in vitro system. The results showed that TaAPY3-1 protein exhibited high catalytic activity in degradation of ATP and ADP, but not GTP, CTP and TTP. It also has an extensive range of temperature adaptability, but rather preferred relative acid pH conditions. In this study, the genome-wide identification and characterization of the APYs in wheat could be useful for further genetic modifications to generate high-stress tolerant wheat cultivars.

Non-specific lipid-transfer proteins (nsLTPs) represent a family of plant antimicrobial peptides (AMPs) implicated in diverse physiological processes. However, their role in induced resistance (IR) triggered by non-pathogenic fungal strains and their metabolites is poorly understood. In this work, using RNA-seq data and our AMP search pipeline, we analyzed the repertoire of nsLTP genes in the wheat Triticum kiharae and studied their expression in response to Fusarium oxysporum infection and treatment with the intracellular metabolites of Fusarium sambucinum FS-94. A total of 243 putative nsLTPs were identified, which were classified into five structural types and characterized. Expression analysis showed that 121 TkLTPs including sets of paralogs with identical mature peptides displayed specific expression patters in response to different treatments pointing to their diverse roles in resistance development. We speculate that upregulated nsLTP genes are involved in protection due to their antimicrobial activity or signaling functions. Furthermore, we discovered that in IR-displaying plants, a vast majority of nsLTP genes were downregulated, suggesting their role as negative regulators of immune mechanisms activated by the FS-94 elicitors. The results obtained add to our knowledge of the role of nsLTPs in IR and provide candidate molecules for genetic engineering of crops to enhance disease resistance.
