DEVELOPING THE TRI-PARENTAL EXOTIC WHEAT POPULATION SW84 Genetic diversity of cultivated wheat was markedly reduced, first, during domestication and, second, since the onset of modern elite breeding. There is an increasing demand for utilizing genetic resources to increase genetic diversity and, simultaneously, to improve agronomic performance of cultivated wheat. To locate favorable effects of...

This article is a Commentary on Calderini et al. (2021), 230: 629-640. ‘What α-expansin and how does its expression increase grain size without triggering compensatory reduction in number?’ Expansin proteins were first discovered as catalysts of ‘acid growth’ (McQueen-Mason al., 1992), the pH-dependent cell growth wall extensibility that occurs under many circumstances, classically case auxin-s...

1974; Barlow et al., 1973; Rogers et al., 1993; Giroux and Morris, 1997, 1998; Bergman et al., 1998; Morris et A complete understanding of the physical–chemical mechanism al., 1999). and underlying genetic control of wheat (Triticum aestivum L.) endosperm texture will contribute to defining optimal grain utilization Regarding the underlying molecular basis of grain while assisting the breeding ...
