New Phytol 173:481-94. 2007..It is concluded, on the basis of transposon mutagenesis, that See2beta has an important role in N-use and resource allocation under N-limited conditions, and a minor but significant function in the later stages of senescence... - Nondestructive analysis of senescence in mesophyll cells by spectral resolution of protein synthesis-dependent pigment metabolismAlan Gay

Institute of Biological, Environmental and Rural Sciences, Aberystwyth University, Ceredigion SY23 3DA, UK
New Phytol 188:161-74. 2010..We conclude that disruption of LHCs, possibly influenced by SGR, and absence of PaO produce phototoxic chlorophyll catabolites and oxidative stress leading to the HR... - Markers and mapping revisited: finding your geneNeil Jones

Theor Appl Genet 110:846-51. 2005..Moreover, when the four BACs were partially sequenced, no obvious coding regions could be identified. This contrasted to BACs identified using cDNA sequences, when multiple genes were identified on the same BAC... - What stay-green mutants tell us about nitrogen remobilization in leaf senescenceHoward Thomas
