Morphology of tubular Ulva from India.
A–D ANJ Isolate, E–H KAR isolate, I–L KUN isolate, M-P MAN isolate, Q–T KAN Isolate and U–X PON Isolate. Arrowheads in M and U indicate flat portions of thalli, J indicate branching pattern and D, H, L, P, T and X indicate pyrenoids. Scale bars are 2 mm for A, E, I, M, Q and U; 200 µm for B, F, J, N, R and V; 100 µm for C, G, K, O, S and W; and 50 µm for D, H, L, P, T and X.

Morphological characters of Indian isolates in comparison with Ulva intestinalis, Ulva compressa and Ulva flexuosa [29], [30].
Figure 2.
Phylogenetic position of tubular Ulva isolates from India among other tubular Ulva accessions in ITS dataset using Maximum Likelihood phylogenetic reconstruction (LnL = −2412.46) with T3P model of molecular evolution with gamma distribution (T3P+G).
Numbers near nodes represent bootstrap support (1000 replicates), exceeding 50. This phylogram is rooted with Ulva prolifera as outgroup. Scale bar given on bottom is in the units of average nucleotide substitutions per site.
Figure 3.
Phylogenetic position of tubular Ulva isolates from India among other tubular Ulva accessions in ITS dataset using Bayesian Inference phylogenetic reconstruction (LnL = −2628.193) with T3P model of molecular evolution with gamma distribution (T3P+G).
Numbers near nodes represent Bayesian Posterior Probabilities, exceeding 0.5. This phylogram is rooted with Ulva prolifera as outgroup. Scale bar given on bottom is in the units of average nucleotide substitutions per site.

Phylogenetic position of tubular Ulva isolates from India among other accessions in ITS dataset using Neighbor-Joining Inference phylogenetic reconstruction (total tree length = 0.79153595) with T3P model of molecular evolution with gamma distribution (T3P+G).
Numbers near nodes represent bootstrap support (100 replicates), exceeding 50. This phylogram is rooted with Blidingia minima as outgroup. Scale bar given on bottom is in the units of average nucleotide substitutions per site.
