Gamma-aminobutyric acid (GABA) is a non-protein amino acid commonly present in all organisms. Because cellular levels of GABA in plants are mainly regulated by synthesis (glutamate decarboxylase, GAD) and catabolism (GABA-transaminase, GABA-T), we attempted seed-specific manipulation of the GABA shunt to achieve stable GABA accumulation in rice. A truncated GAD2 ...

Historically, 'physical dormancy', or 'hard seededness', where seeds are prevented from germinating by a water-impermeable seed coat, is viewed as a dormancy mechanism. However, upon water uptake, resumption of metabolism leads to the unavoidable release of volatile by-products, olfactory cues that are perceived by seed predators. Here, we examine the ...

N-Phenyl-2-naphthylamine (P2NA) was widely used as oxidation inhibitor, particularly in rubber manufacturing. Technical-grade P2NA was contaminated with carcinogenic 2-naphthylamine (2NA), and bladder cancer risk in exposed workers was attributed to this impurity. Investigations in humans and mammalian species revealed that small amounts of 2NA are excreted into urine after exposure ...

The actinobacterium Rhodococcus opacus 1CP possesses a so far unique variant of the modified 3-oxoadipate pathway for 3-chlorocatechol degradation. One important feature is the novel dehalogenase ClcF, which converts (4R,5S) 5-chloromuconolactone to E-dienelactone. ClcF is related to muconolactone isomerase (MLI, EC 5.3.3.4). The enzyme has a ferredoxin-type fold and forms ...

Severe intraspecific competition for mates selects for aggressive individuals but may also lead to the evolution of alternative phenotypes that do not act aggressively, yet manage to acquire matings. The two-spotted spider mite, Tetranychus urticae, shows male mate-guarding behaviour and male-male combat for available females. This may provide opportunity for ...
