ARGININE IS A COMPONENT OF THE AMMONIUM-CYG56 SIGNALLING CASCADE THAT REPRESSES GENES OF THE NITROGEN ASSIMILATION PATHWAY IN CHLAMYDOMONAS REINHARDTII.

Nitrogen assimilation and metabolism are essential processes for all living organisms, yet there is still much to be learnt on how they are regulated.The use of Chlamydomonas reinhardtii as a model system has been instrumental not only in identifying conserved regulation mechanisms that control the nitrogen assimilation Stevia pathway, but also in

Mesoscale dynamics are a fundamental process in space physics, but fall within an observational gap of current and planned missions.Particularly in the solar wind, measurements at the mesoscales (100s RE to a few degrees heliographic longitude at 1 au) are crucial for understanding the connection between the corona and an observer anywhere within t

The swelling phenomenon of expansive soil is considered one of the most serious problems that face geotechnical engineers.The principal purpose of this study is to investigate the effectiveness of geogrid for reinforcing sand cushion on the heave of isolated footing resting on a top of halter a sand cushion underlined by highly active expansive cla

Despite multiple recent field studies, herpetological species diversity of the Romblon Island Group in the central Philippines—particularly Sibuyan Island—has remained underestimated.Recently, we investigated the diversity of the herpetofauna of Mount Guiting-Guiting Natural Park, based on an elevational transect (10–1
