Analysis of the transcriptome of the developing wheat grain has associated expression of genes with traits involving production (e.g. yield) and quality (e.g. bread quality). Photosynthesis in the grain may be important in retaining carbon that would be lost in respiration during grain filling and may contribute to yield in the late stages of seed formation under warm and dry environments. A small number of genes have been identified as having been selected by humans to optimize the performance of wheat for foods such as bread. Genes determining flour yield in milling have been discovered. Hardness is explained by variations in expression of pin genes. Knowledge of these genes should dramatically improve the efficiency of breeding better climate adapted wheat genotypes.
分析发育中的麦粒的转录组，与涉及产量（例如，产量）和质量（例如，面包质量）的性状相关的基因表达有关。在谷物中进行光合作用对于保留在谷物填充过程中呼吸作用中损失的碳可能很重要，并且在温暖和干燥的环境下，在种子形成的后期阶段可能有助于产量。已经确定了少数几个基因，这些基因被人类选择，以优化小麦的性能，使其更适合制作面包等食物。已经发现了决定面粉产量的磨粉基因。硬度由针基因表达的变化来解释。这些基因的知识应该大大提高培育更适应气候的小麦基因型的效率。
