The aim of this study was to explore the use of TD-NMR relaxometry and 1 H NMR spectroscopy-based for detecting differences in meat quality attributes. There was limited association between various TD-NMR signals and any physicochemical parameters of fresh and aged meat differing in tenderness ratings. Samples were then divided into three groups based on statistical changes in metabolite concentration. Group A samples possessed near linear increases in metabolite concentration over aging time; whereas samples assigned to Groups B and C were characterized by increases in metabolites that peaked between 7 and 14 days, and up to 14 days aging, respectively. 1 H NMR spectroscopy discriminated meat quality using changes in metabolites reflective of glycolysis, the citric acid cycle, protein degradation, amino acid generation and purine metabolisms. These data suggest segregation of meat quality is possible using both NMR technologies but additional work is necessary to understand fully their utility in a commercial industry setting. |

Meloidogyne incognita is one of the most important plant-parasitic nematodes (PPNs) causing severe crop losses worldwide. Plants have evolved complex defense mechanisms to respond to PPNs attacks. Conversely, PPNs have evolved infection mechanisms that involve the secretion of effector proteins into host plants to suppress immune responses and facilitate para- sitism. Therefore, effector genes are attractive targets for the genetic improvement of plant resistance to M. incognita. In this study, we functionally characterized the Minc16803 (Minc3s00746g16803) putative effector gene to evaluate its role during plant-nematode interactions. First, we found that the Minc16803 gene is expressed in all nematode life stages and encodes a protein with an N-terminal signal peptide for secretion, a motif characteristic of effector proteins and with the absence of transmembrane domain. In addition, our data demonstrated that transgenic Arabidopsis thaliana lines overexpressing a Minc16803-dsRNA efficiently downregulated the Minc16803 transcripts in infecting nematodes. Furthermore, transgenic lines were significantly less susceptible to M. incognita compared to wild-type control plants. The number of galls per plant was reduced by up to 84%, while the number of egg masses per plant decreased by up to 93.3%. Moreover, galls and feed- ing sites in the roots of transgenic lines were smaller than those in the control plants. Histological analysis revealed giant cells without cytoplasm, disordered neighboring cells, and malformed maturing nematodes in transgenic galls. Curiously, numerous hatching ppJ2 juveniles were often observed near the female body within the transgenic root tissues before egg mass extrusion. All findings strongly suggest that Minc16803 gene is a promising target to engineer agricultural crops for M. incognita resistance through host-induced gene silencing.
