Popis: | Fluorescent reporters have facilitated non-invasive imaging in multiple plant species and thus allowed analysis of processes ranging from gene expression and protein localization through to cellular patterning. However, in rice, a globally important crop and model species, there are relatively few reports of fluorescent proteins being used in leaves. Fluorescence imaging is particularly difficult in the rice leaf blade, likely due to a high degree of light scattering in this tissue. To address this, we investigated approaches to improve deep imaging in mature rice leaf blades. We found that ClearSee treatment, which has previously been used to visualise fluorescent reporters in whole tissues of plants, led to improved imaging in rice. Removing epidermal and subtending mesophyll cell layers was faster than ClearSee, and also reduced light scattering such that imaging of fluorescent proteins in deeper leaf layers was possible. To expand the range of fluorescent proteins suitable for imaging in rice, we screened twelve whose spectral profiles spanned most of the visible spectrum. This identified five proteins, mTurquoise2, mClover3, mNeonGreen, mKOκ and tdTomato that are robustly expressed and visible in mesophyll cells of stably transformed plants. Using microparticle bombardment, we show that mTurquoise2 and mNeonGreen can be used for simultaneous multicolour imaging of different sub-cellular compartments. Overall, we conclude that mTurquoise2, mClover3, mNeonGreen, mKOκ and tdTomato are suitable for high resolution live imaging of rice leaves, both after transient and stable transformation. Along with the rapid microparticle bombardment method, which allows transient transformation of major cell types in the leaf blade, these fluorescent reporters should greatly facilitate the analysis of gene expression and cell biology in rice.One sentence summaryWe report five fluorescent reporters suitable for functional analysis in rice leaves. |
