It is shown that the monovinyl and divinyl protochlorophyllide biosynthetic patterns of etiolated maize (Zea mays L.), and cucumber (Cucumis sativus L.) seedlings and of their isolated etiochloroplasts can be modulated by light and darkness as was shown for green photoperiodically grown plants (E. E. Carey, C. A. Rebeiz 1985 Plant Physiol. 79: 1-6). In etiolated corn and cucumber seedlings and ...
European flint × U.S. dent is the most common heterotic pattern used in early maize (Zea mays L.) breeding programs in Spain. Two synthetic maize populations, EZS1 (formed from four Spanish flint populations), and EZS2 (formed from four American dent populations), were developed in Zaragoza, Spain. These synthetics, which showed heterotic behaviour, were subjected to six cycles of S1 recurrent ...
To determine the optimal ploughing depth and to make tillage simpler and less costly, but also taking account of edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2009) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. Th e paper presents the results relating to plant de...
Maize (Zea mays L.) plays a very important role in human and animal nutrition in a number of developed and developing countries, worldwide. Breeding for improved protein quality in maize began in the mid-1960s with the discovery of mutants, such as opaque-2, that produce enhanced levels of lysine and tryptophan, the two amino acids deficient in maize endosperm proteins. However, adverse pleiotr...
Modern crops have usually experienced domestication selection and subsequent genetic improvement (post-domestication selection). Chinese waxy maize, which originated from non-glutinous domesticated maize (Zea mays ssp. mays), provides a unique model for investigating the post-domestication selection of maize. In this study, the genetic diversity of six key genes in the starch pathway was invest...
