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

对根系孔隙度的测定表明，在缺磷条件下，气孔的形成速度更快，对缺磷耐受性较高的基因型尤其明显。这些结果通过更详细的细胞学检查结合图像分析工具得到证实。与Nerica4相比，耐氧基因型DJ具有更高的通气组织比例，并且在缺磷条件下进一步增加。因此，通气组织的形成是一种候选机制，可以解释为什么DJ通常在低投入条件下表现更好，特别是为什么当磷是限制因素时，它能够在生物量积累中更有效地利用磷。对三个已知参与空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而不是结论性的数据。它确定了几个候选基因在对比基因型中差异表达。这需要进一步的研究来跟进。一份描述他在通气组织方面工作的手稿即将完成，并将很快提交审稿。此外，他在RNA-Seq数据集的生物信息学分析方面的协助有助于完成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.
