イネのリン吸収における根圏域および根圏微生物の影響

根孔隙度的测量表明，在缺磷的情况下，通气组织的形成更快，并且对于对缺磷耐受性较高的基因型来说，这一点尤其强烈。使用更详细的细胞学检查结合图像分析工具证实了这些结果。耐基因型DJ有较高比例的通气组织相比，Nerica 4，这进一步增加在缺磷条件下。通气组织的形成，因此，可以解释为什么DJ通常在低输入条件下表现更好的候选机制之一，特别是为什么它能够更有效地利用P生物量积累时，P是限制因素。三个已知参与通气组织形成的基因家族的基因表达模式的分析产生了暗示性的，而不是结论性的数据。它确定了一些候选基因差异表达的对比基因型。需要进一步的研究来跟进这一点。一份描述他在通气组织方面工作的手稿即将完成，不久将提交审查。此外，他对RNA-Seq数据集的生物信息学分析的协助有助于完成Nanda博士的研究。这项工作目前正在审查之中。

Measurements of root porosity suggested that formation of aerenchyma is more rapid under P deficiency and that this is particularly strong for the genotype with higher tolerance to P deficiency. These results were confirmed using more detailed cytological examinations in combination with image analysis tools. The tolerant genotype DJ had a higher proportion of aerenchymatic tissue compared to Nerica4 and this further increased under P deficient conditions. Aerenchyma formation is thus one of the candidate mechanisms that may explain why DJ is generally performing better under low-input conditions, and specifically why it is capable of utilizing P more efficiently in biomass accumulation when P is the limiting factor.Analysis of gene expression patterns for three gene families known to be involved in aerenchyma formation produced suggestive rather than conclusive data. It identified a few candidate genes differentially expressed in contrasting genotypes. Further studies are needed to follow up on this. A manuscript describing his work on aerenchyma is nearing completion and will be submitted for review soon.Furthermore, his assistance with the bioinformatics analysis of the RNA-Seq dataset was instrumental in completing the study of Dr. Nanda. This work is now under review.
