To study the characteristics of changes on rice mutants induced in space environment, we analyzed
proteins in leaves and seeds of four rice mutants (two high tillering and two low tillering) in the 8th and
9th generations after a 15 day spaceflight, and compared with their ground controls by reverse phase
liquid chromatography (RPLC). The results showed that the low abundance proteins of leaves in the
peak tillering stage are more likely to be induced compared with their corresponding controls. The
albumin, globulin, and prolamine of the mutant seeds revealed changes when compared with their
controls, and the characteristics of changes in different mutants
were stably inherited in the 8th and 9th generations, suggesting that
they can be used as biomarkers to
identity the mutants induced by spaceflight.

Pattern formation
controlled by external forcing in a spatial harvesting predator-prey model
Feng Rao, Weiming Wang, Zhibin Li
In this paper, we present a spatial version
of the Ivlev-type predation-di®usion model which contains
external periodic forcing and harvest on prey. From the numerical results, our results show that external
periodic forcing plays a concernful role in the predation-di®usion model with constant harvest.
