小麦蛋白体的发育决定了其加工特性。众所周知，氮素吸收对籽粒蛋白质浓度有很大影响。但是，小麦胚乳中不同发育阶段和不同部位的PB形成的差异仍存在争议。为了解决这些问题，本研究利用光镜和透射电镜研究了小麦胚乳不同部位中PBs的形成及其对氮素的响应。主要结果如下。(1)在小麦胚乳发育的早期，蛋白质主要通过液泡中的高尔基体形成PB。开花后7天，大部分蛋白质来源于粗面内质网。(2)胚乳不同部位的PBs形态各异。与中央胚乳相比，亚糊粉层细胞中的PB丰富且大。(3)氮素处理后，早期内质网、高尔基体和内质网数量增多。氮素还增加了后期多溴联苯的积累。(4)胚乳亚糊粉层区细胞对氮素的反应比胚乳中央细胞更显著。
The development of protein bodies (PBs) determines the processing properties of wheat (Triticum aestivumL.). It has been known that nitrogen uptake has a strong impact on grain protein concentration. However, the differences of the formation of PB in different developmental stages and different positions in wheat endosperm are still controversial. To solve these issues, PBs formation in different wheat endosperm parts and the response to nitrogen were investigated using light, transmission electron microscopes in present study. The main results were as follows. (1) Proteins mainly formed PBs via the Golgi apparatus in the vacuole at the early stage of wheat endosperm development. After 7 days post anthesis, most proteins were derived from the rough endoplasmic reticulum. (2) The morphology of PBs was diverse among different endosperm parts. Compared with the central endosperm, the PBs in sub-aleurone cells were abundant and large. (3) More abundant endoplasmic reticulum, Golgi and mitochondrion were observed at the early stage after nitrogen treatment. Nitrogen also increased the accumulation of PBs at the later stage. (4) The sub-aleurone region cells of the endosperm presented more significant responses to nitrogen than the central endosperm.
