CesA (cellulose synthase) genes of Arabidopsis; all doing the same job or specialists cooperating to make the most abundant biopolymer. The biosphere makes more cellulose than any other polymer with fibre industries depending on its physical properties and atmospheric carbon dioxide levels depending on its stability as a carbon sink. Demonstrations that cellulose production needs CesA genes drove recent progress in elucidating the mechanism of synthesis. CesA proteins all look very similar but if all do the same job, why do plants need so many and why do none seem redundant? We will make gene interchanges in transgenic plants, build chimeric genes and identify where each CesA protein operates. This will identify their individual and cooperative contributions to cellulose production.

拟南芥的CESA(纤维素合成酶)基因；所有人都在做同样的工作，或者专家们合作制造最丰富的生物聚合物。生物圈产生的纤维素比任何其他纤维工业聚合物都多，这取决于它的物理性质，以及大气中的二氧化碳水平，这取决于它作为碳汇的稳定性。证明纤维素生产需要CESA基因，这推动了最近在阐明合成机制方面的进展。CESA蛋白质看起来都非常相似，但如果所有蛋白质都做同样的工作，为什么植物需要这么多蛋白质，为什么没有蛋白质看起来是多余的？我们将在转基因植物中进行基因交换，构建嵌合基因，并确定每个CESA蛋白的作用位置。这将确定他们对纤维素生产的个人和合作贡献。
