Methods to evaluate wheat cultivar testing environments and improve cultivar selection protocols
Analysis of cultivar by environment (C E) interaction can improve efficiency of crop breeding efforts. Variety selection and recommendation based on wheat (Triticum aestivum L.) yield testing trials could possibly benefit from this type of analysis as well. The objectives of the present work were to evaluate methods to identify relevant testing environments and improve the predictive value of d...
متن کاملELUCIDATION OF THE STRUCTURE OF METALLOTHIONEINS BY Cd-113 AND PROTON NMR
Metaliothioneins (MTs) are a class of low molecular weight (^6100 dalton), cysteine-rich, heavy metal binding proteins. First isolated over 25 years ago from equine renal cortex (1), MTs have subsequently been found to be ubiquitously distributed in the animal and plant kingdoms and also in some procaryotes (2). Heavy metals have been shown to act as inducers at the transcriptional level iji vi...
متن کاملUse of (113)Cd NMR to probe the native metal binding sites in metalloproteins: an overview.
Our laboratories have actively published in this area for several years and the objective of this chapter is to present as comprehensive an overview as possible. Following a brief review of the basic principles associated with (113)Cd NMR methods, we will present the results from a thorough literature search for (113)Cd chemical shifts from metalloproteins. The updated (113)Cd chemical shift fi...
متن کاملNitric oxide, polyamines and Cd-induced phytotoxicity in wheat roots.
To further explore the biochemical basis of Cd toxicity in developing wheat seedlings, we studied the possible role of nitric oxide (NO) and polyamines as signaling molecules involved in metal-induced root growth inhibition. When used at 0.1 mM, sodium nitroprusside, a NO-releasing compound, inhibited root growth to a similar extent as Cd and enhanced the polyamine contents as Cd also did. Putr...
متن کاملPhysiological, genetic, and molecular characterization of a high-Cd-accumulating rice cultivar, Jarjan.
Cadmium (Cd) in rice is a major source of Cd intake for people on a staple rice diet. The mechanisms underlying Cd accumulation in rice plant are still poorly understood. Here, we characterized the physiology and genetics of Cd transport in a high-Cd-accumulating cultivar (Jarjan) of rice (Oryza sativa). Jarjan showed 5- to 34-fold higher Cd accumulation in the shoots and grains than the cultiv...
