<p>Table S1 Carotenoid and chlorophyll content of detached cassava leaves following salt and drought stress treatment. Leaves from cassava plants grown in vitro were detached and incubated in 250 mM NaCl (salt) or 40 % (w/v) PEG 6000 in propagation medium (drought) for the times indicated. Control plants were transferred into fresh propagation medium and harvested at the same times (control). Carotenoids were quantified by HPLC. vio/neo, violaxanthin and neoxanthin; o. xan., other xanthophylls; lut, lutein, a-caro, -carotene; b-caro, -carotene, chl, chlorophyll. Data are given in nmol mg-1 DW and represent the mean ±SD of two technical replicates</p><p>Sample vio/neo o. xan lut -caro -caro total caros chl a chl b chl a/chl b 0 h 1.20±0.00 1.56 ±0.33 4.32±0.25 0.05±0.00 1.99±0.10 9.05±0.28 15.06±0.20 4.16±0.04 3.62±0.02 2 h control 1.41±0.01 1.59±0.43 4.69±0.13 0.08±0.01 2.09±0.08 9.78±0.39 16.36±0.38 4.43±0.40 3.70±0.02 6 h control 1.32±0.16 1.49±1.52 4.18±0.07 0.04±0.01 1.92±0.36 8.88±1.08 14.52±0.88 4.24±0.27 3.43±0.01 12 h control 1.03±0.16 1.42±0.10 3.94±0.08 0.05±0.00 1.62±0.04 8.02±0.12 13.57±0.40 3.71±0.22 3.65±0.11 16 h control 1.09±0.11 1.43±0.48 4.03±0.09 0.04±0.01 1.59±0.05 8.12±0.35 13.02±0.82 3.04±0.31 4.28±0.11 2 h drought 1.29±0.01 1.54±0.60 4.39±0.14 0.04±0.01 1.90±0.19 9.09±0.55 15.25±0.61 4.61±0.33 3.31±0.01 6 h drought 1.04±0.08 1.42±0.22 4.38±0.07 0.04±0.01 1.83±014 8.64±0.33 14.61±0.62 4.13±0.26 3.54±0.13 12 h drought 0.77±0.08 1.50±0.44 4.05±0.07 0.06±0.02 1.46±0.04 7.80±0.19 12.99±0.51 3.79±0.15 3.43±0.03 16 h drought 0.73±0.14 1.53±0.10 3.50±0.13 0.04±0.00 1.32±0.07 7.08±0.31 10.76±0.44 3.59±0.29 3.00±0.12 2 h salt 1.27±0.17 1.51±0.20 4.57±0.24 0.05±0.00 2.03±0.26 9.36±1.30 15.66±1.09 4.44±0.29 3.53±0.07 6 h salt 1.15±0.22 1.41±0.37 4.19±0.16 0.05±0.01 1.94±0.42 8.69±1.77 14.76±1.84 4.18±0.41 3.53±0.00 12 h salt 1.13±0.05 1.45±0.13 4.51±0.18 0.06±0.00 1.77±0.09 8.88±0.51 14.45±0.99 4.01±0.49 3.60±0.13 16 h salt 1.28±0.56 1.76±0.58 5.07±0.78 0.07±0.03 1.86±0.62 9.98±1.23 15.71±0.96 4.42±0.35 3.56±0.01</p>
