Invasion promotes invasion: Facilitation of C 3 perennial grass dominance in mixed C 3 /C 4 grassland by an invasive C 3 woody sprouter ( Prosopis glandulosa )

Assimilatory sulfate reduction in C(3), C(3)-C(4), and C(4) species of Flaveria.

The activity of the enzymes catalyzing the first two steps of sulfate assimilation, ATP sulfurylase and adenosine 5'-phosphosulfate reductase (APR), are confined to bundle sheath cells in several C(4) monocot species. With the aim to analyze the molecular basis of this distribution and to determine whether it was a prerequisite or a consequence of the C(4) photosynthetic mechanism, we compared ...

It is probably very hard to develop a new model checker that is faster than UPPAAL for verifying (correct) timed automata. In fact, our tool MCTA does not even try to compete with UPPAAL in this (i. e., UPPAAL’s) arena. Instead, MCTA is geared towards analyzing incorrect specifications of timed automata. It returns (shorter) error traces faster.

Preparation of Precocene 2 and 3 , 4 - Epoxyprecocene 2 Deuterated Analogues at C - 3 , C - 4 and C - 3 , C - 4

Precocene Analogues, Deuteration A convenient route for the preparation of title compounds from benzopyran-4-one (1) and its corresponding 3,3-H2 deuterated analogue (2) is reported. Treatment of 1 or 2 with lithium aluminum deuteride followed by dehydration afforded, respectively, 4-H precocene (3c) or 3,4-H2 precocene (3b). Likewise, reduction of 2 with lithium aluminum hydride and subsequent...
