Journal ArticleDOI
Temperature stress and plant sexual reproduction: uncovering the weakest links
TL;DR: Studies of temperature stress on several crop plants suggest that pollen development and fertilization may often be the most sensitive reproductive stage, which offers the potential to identify genetic traits that could be manipulated to improve temperature tolerance in selected crop species being cultivated in marginal climates.
Journal ArticleDOI
Riboswitch Control of Gene Expression in Plants by Splicing and Alternative 3′ End Processing of mRNAs
Andreas Wachter,Meral Tunc-Ozdemir,Beth C. Grove,Pamela J. Green,David K. Shintani,Ronald R. Breaker,Ronald R. Breaker +6 more
TL;DR: It is demonstrated that riboswitch-mediated regulation of alternative 3′ end processing is critical for TPP-dependent feedback control of THIC expression, and a mechanism whereby metabolite-dependent alteration of RNA folding controls splicing and alternative 3″ end processing of mRNAs is revealed.
Journal ArticleDOI
Thiamin confers enhanced tolerance to oxidative stress in Arabidopsis.
Meral Tunc-Ozdemir,Gad Miller,Luhua Song,James Kim,Ahmet Sodek,Shai Koussevitzky,Amarendra Narayan Misra,Ron Mittler,David K. Shintani +8 more
TL;DR: These studies suggest that thiamin and TPP function as important stress-response molecules that alleviate oxidative stress during different abiotic stress conditions.
Journal ArticleDOI
A Cyclic Nucleotide-Gated Channel (CNGC16) in Pollen Is Critical for Stress Tolerance in Pollen Reproductive Development
Meral Tunc-Ozdemir,Chong Tang,Maryam Rahmati Ishka,Elizabeth Brown,Norman Reid Groves,Candace T. Myers,Claudia Rato,Lisbeth R. Poulsen,Stephen C. McDowell,Gad Miller,Ron Mittler,Jeffrey F. Harper +11 more
TL;DR: In this article, genetic evidence identifies CNGC16 in Arabidopsis (Arabidopsis thaliana) as critical for pollen fertility under conditions of heat stress and drought, and two independent transfer DNA disruptions of cngc16 resulted in a greater than 10-fold stress-dependent reduction in pollen fitness and seed set.
Journal ArticleDOI
Reciprocal Encoding of Signal Intensity and Duration in a Glucose-Sensing Circuit
Yan Fu,Sungmin Lim,Daisuke Urano,Meral Tunc-Ozdemir,Nguyen Phan,Timothy C. Elston,Alan M. Jones +6 more
TL;DR: A reciprocal dose and duration response relying on the orchestrated action of three kinases acting on distinct timescales and activation thresholds is discovered, allowing encoding of both the intensity and persistence of glucose as an important energy resource and signaling molecule.
