Regulation of reserve carbohydrates in hull-less barley grain
… altered the amount of (1,3;1,4)-β-glucan in the grain, however, the effects of modifying (1,3;1,4)-β-glucan on various carbohydrate metabolic pathways and its impact on grain development have not previously been clearly defined. Here, we used transgenic grain with increased (1,3;1,4)-β-glucan and …

Understanding the genetic and physiological control of pre-harvest sprouting and pre-maturity amylase in UK wheat
… amylase (PMA) are physiological defects in wheat grains that reduce their end-use quality. PHS is the precocious germination of grains before harvest while PMA is the accumulation of α-amylase in grains. Both traits are quantitative in their expression and are strongly influenced by the …

Enhancing photosynthetic capacity and energy conversion in wheat
Wheat is one of the major grain crops worldwide and provides approximately 20% of the total caloric and protein input for the world’s population. An increase in crop yields is required to meet the demands of the increasing world population in a challenging scenario of less predictable climatic …

Influence of timing of nitrogen application on yield and nutrient uptake of winter wheat (Triticum aestivum L.)
… These were applied at specific stages of wheat development. A control treatment was included to determine the contribution of indigenous soil N to grain yield and nitrogen uptake. Grain yields were increased by a split application of 134.4 kg N/ha (67.2 at G.S. 3.0 and 67.2 at G.S. 10.5) in …

The NAM-B1 transcription factor and the control of grain composition in wheat
The NAM-B1 transcription factor increases grain protein content, alters grain micronutrient content and accelerates monocarpic senescence, often without imposing a yield penalty. The aim of this thesis was to understand the mechanisms by which NAM-B1 influences nutrient remobilisation and …

Adaptation of wheat to a tropical environment
… processing and this has increased with economic development. Therefore to lower the high import of wheat grains, Indonesia should have domestic production. Even though Indonesia straddles the equator, the high altitudes in many parts of Indonesia means that wheat could potentially be grown during …
