Distribution of conserved miRNA family members in potato.

<p>Graphical representation of the different members of conserved miRNA families found in potato by sequencing and bioinformatics prediction.</p

Size distribution of small RNA sequences.

<p>(A) Reads and unique sequence distribution in all the small RNA libraries. 24 and 21nt length reads are the most abundant reads among the small RNAs. (B) Size distribution of reads originating from leaf (dark grey) and stolon (light grey) tissues expressed as a percentage of total reads. 24 and 21nt length reads are dominant in both of the tissues; in stolon tissues there are more reads for 21, 23 and 24nt length.</p

Reads length analysis of the predicted unique miRNA and star (miRNA*) sequences.

<p>Graph shows that most miRNAs and star sequences have 24 and 21 nt length. Star sequences show different distribution compared to miRNAs; there are less star sequences with 17, 20, 21 and 24 nt length but more in other length categories.</p

Origin of miRNA precursors.

<p>The majority of miRNA precursors are transcribed from intergenic regions. miRNA precursors originating from coding regions locates mainly in introns.</p

Variation of the normalised temperature for each genotype ranked by mean temperature.

<p><b>A</b>) Graphical representation of the consistency of the rankings of the different genotypes across three measurement dates for Trial 4. The genotypes are ranked along the x-axis according to the mean of all the replicate normalised genotype temperatures (°C) over three days. The X-axis also indicates the positions for the two parents (HB171, 99FT1b5) and two commercial varieties (Var1 = Record and Var2 = Cara). <b>B</b>) The same data as (A) but with data randomly assigned to ‘genotypes’ independently on each day, indicating the range of genotype means that could have arisen by chance. This confirms that the substantial genotypic differences in mean normalised temperature shown in (A) are not due to chance. LSD values presented at 95% level in all graphs.</p

Visual (RGB) image and corresponding thermal image of part of the potato field trial.

<p><b>A</b>): Visual image of the randomised potato field trial showing markers to aid localisation in the thermal image. The marked circle indicates one of the two-plant plots. <b>B</b>) Corresponding thermal image; this shows the selected area of canopy for each plot isolated in the ThermaCAM Researcher Pro software.</p

Canopy temperature (°C) variation within images and between successive images.

<p>Dot plot covering measurements on three trials on a single day showing the substantial temporal variation, with the major reduction in temperatures between images 34 and 42 resulting from variability in environmental components. Each cross represents the temperature of a single plot in one image.</p

Effect of replication and normalisation.

<p>Illustration of the benefits of image overlaps and of normalisation for calculating the genotype means during thermal image analyses (using the example of Trial 4_Day1 data). The two replicates are indicated using different symbols. <b>A</b>) Relationship between individual plot temperature (IPT) on y-axis and Genotype Means. <b>B</b>) Relationship between the “individual-image normalised plot temperature” (IINPT) and Genotype Means. <b>C</b>) Relationship between Normalised Plot Temperature (NPT) and Genotype Means. Note: Residual errors as a measure of the difference.</p
