The genotype-specific defense activation in the roots of perennial tree crops to soilborne necrotrophic pathogens remains largely unknown.A recent phenotyping study indicated that the apple rootstock genotypes B.9 and G.935 have contrasting resistance responses to infection by Pythium *** the current study,a comparative transcriptome analysis by Illumina Solexa HiSeq 3000 platform was carried out to identify the global transcriptional regulation networks between the susceptible B.9 and the resistant G.935 to *** ***-six libraries were sequenced to cover three timepoints after pathogen inoculation,with three biological replicates for each *** transcriptomes in the roots of the susceptible genotype B.9 were reflected by overrepresented differentially expressed genes(DEGs)with downregulated patterns and systematic suppression of cellular processes at 48 h post inoculation(hpi).In contrast,DEGs with annotated functions,such as kinase receptors,MAPK signaling,JA biosynthesis enzymes,transcription factors,and transporters,were readily induced at 24 hpi and continued upregulation at 48 hpi in G.935 *** earlier and stronger defense activation is likely associated with an effective inhibition of necrosis progression in G.935 *** of effector-triggered immunity or existence of a susceptibility gene could contribute to the severely disturbed transcriptome and susceptibility in B.9 *** identified DEGs constitute a valuable resource for hypothesis-driven studies to elucidate the resistance/tolerance mechanisms in apple roots and validating their potential association with resistance traits.

Carotenoid Metabolism in Plants： The Role ol Plastids

Carotenoids are indispensable to plants and critical in human diets. Plastids are the organelles for carotenoid biosynthesis and storage in plant cells. They exist in various types, which include proplastids, etioplasts, chloroplasts, amyloplasts, and chromoplasts. These plastids have dramatic differences in their capacity to synthesize and sequester carotenoids. Clearly, plastids play a central role in governing carotenogenic activity, carotenoid stability, and pigment diversity. Understanding of carotenoid metabolism and accumulation in various plastids expands our view on the multifaceted regulation of carotenogenesis and facilitates our efforts toward developing nutrient-enriched food crops. In this review, we provide a comprehensive overview of the impact of various types of plastids on carotenoid biosynthesis and accumulation, and discuss recent advances in our understanding of the regulatory control of carotenogenesis and metabolic engineering of carotenoids in light of plastid types in plants.
