TL;DR: Bioactivity-directed fractionation of the ethanol extract of the bark of Annona bullata Rich has led to the isolation of the new nonadjacent bis-tetrahydrofuran acetogenins, bullatanocin, cis- and trans-bullatalicinone, and 4-deoxyasimicin, which shows cytotoxic potencies 10,000 times those of adriamycin in the lung and colon cancer cell lines.

TL;DR: The data indicate that the recent amplification of a single-copy MgDNMT gene made it susceptible to RIP, resulting in complete loss of cytosine methylation in M. graminicola, which most likely occurred within the past 10,500 years since the divergence between M. Graminicola and S1.

TL;DR: Support is provided for the idea that the y1 gene regulates the biosynthesis of both 3-deoxyanthocyanidin phytoalexins and phlobaphene pigments in sorghum.

TL;DR: The combination of (1)H NMR and PCA is a useful tool for the discrimination of maize silks in respect to their chemical composition, including rapid authentication of the raw material of current pharmacological interest.
