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

根孔隙度的测定表明，缺磷条件下透气组织的形成速度更快，对耐缺磷能力较强的品种来说，这种情况尤为明显。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。耐磷品种DJ的透气组织比例高于耐磷品种Nerica4，在缺磷条件下这一比例进一步增加。因此，通风组织的形成是一个候选机制，可以解释为什么DJ在低输入条件下表现得更好，特别是为什么当P是限制因素时，它能够更有效地利用P来积累生物量。对三个已知的参与通风组织形成的基因家族的基因表达模式的分析产生了提示性的而不是决定性的数据。它确定了几个在不同基因类型中差异表达的候选基因。这还需要进一步的研究来跟进。描述他在通风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对Nanda博士的研究。这项工作目前正在审查中。

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.
