Journal ArticleDOI
Wheat grain development is characterized by remarkable trehalose 6-phosphate accumulation pregrain filling: tissue distribution and relationship to SNF1-related protein kinase1 activity
Eleazar Martinez-Barajas,Thierry L. Delatte,Henriette Schluepmann,Gerhardus J. de Jong,Govert W. Somsen,Cátia Nunes,Lucia F. Primavesi,Patricia Coello,Rowan A. C. Mitchell,Matthew J. Paul +9 more
TL;DR: The data show a correlation between T6P and sucrose overall that belies a marked effect of tissue type and developmental stage on T 6P content, consistent with tissue-specific regulation of SnRK1 by T6p in wheat grain.
Journal ArticleDOI
The Trehalose 6-Phosphate/SnRK1 Signaling Pathway Primes Growth Recovery following Relief of Sink Limitation
Cátia Nunes,Liam E. O’Hara,Lucia F. Primavesi,Thierry L. Delatte,Henriette Schluepmann,Govert W. Somsen,Anabela Bernardes da Silva,Pedro Fevereiro,Astrid Wingler,Matthew J. Paul +9 more
TL;DR: It is concluded that the T6P/SnRK1 signaling pathway responds to Suc induced by sink restriction that enables growth recovery following relief of limitations such as low temperature.
Journal ArticleDOI
Inhibition of SnRK1 by metabolites: Tissue-dependent effects and cooperative inhibition by glucose 1-phosphate in combination with trehalose 6-phosphate
Cátia Nunes,Lucia F. Primavesi,Mitul Patel,Eleazar Martinez-Barajas,Stephen J. Powers,Ram Sagar,Pedro Fevereiro,Pedro Fevereiro,Benjamin G. Davis,Matthew J. Paul +9 more
TL;DR: Inhibition of SnRK1 by R5P in wheat grain preparations can be explained by the presence of green pericarp tissue; this exposes an important caveat in the assessment of potential protein kinase inhibitors.
Journal ArticleDOI
Physiological responses of the legume model Medicago truncatula cv. Jemalong to water deficit
Cátia Nunes,Susana de Sousa Araújo,Jorge Marques da Silva,Manuel Pedro Salema Fevereiro,Manuel Pedro Salema Fevereiro,Anabela Bernardes da Silva +5 more
TL;DR: Drought tolerance mechanisms involving osmotic adjustment and an increase in cell membrane integrity allowed Jemalong plants to still maintain a quite elevated level of net CO2 fixation rate under severe water deficit conditions, and may contribute to identify useful physiological traits for breeding programs concerning drought adaptation in legumes.
Journal ArticleDOI
Design and Analysis of Cognitive Interviews for Comparative Multinational Testing
Kristen Miller,Rory Fitzgerald,José-Luis Padilla,Stephanie Willson,Sally Widdop,Rachel Caspar,Martin Dimov,Michelle Gray,Cátia Nunes,Peter Prüfer,Nicole Schöbi,Alisu Schoua-Glusberg +11 more
TL;DR: This article summarizes the work of the Comparative Cognitive Testing Workgroup, an international coalition of survey methodologists interested in developing an evidence-based methodology for examining the comparability of survey questions within cross-cultural or multinational contexts.
