The Status

The effect of tunicamycin, the inhibitor of protein N-glycosylation, on the root and hypocotyl growth of flax seedlings (Linum usitatissimum L.) was studied. It is known that tunicamycin inhibits the first stage of the formation of the oligosaccharide precursor, which is necessary to initiate the synthesis of N-glycoproteins by inhibiting the activity of N-acetylglucosamine phosphotransferase. The blocking by tunicamycin (25 μM) the early stages of N-glycoprotein formation induced growth inhibition in flax seedlings depending on the age of the plants. So one-day-old seedlings, tunicamycin significantly suppressed the growth of hypocotyls and main roots but the inhibitory effect of the antibiotic on the roots was more significant. The tunicamycin effect on the hypocotyl growth began to appear 60 h after using the inhibitor, while the roots completely stopped growth after 30 h. In two-day-old tunicamycin-treated seedlings, hypocotyl elongation proceeded at approximately the same rate as in untreated plants and suppression of root growth was manifested only for 60 h. The vital staining of ER (Endoplasmic Reticulum)-structures of control and tuncamycin-treated one-day-old flax seedlings by using of ER-TrackerTM Green dye revealed the growth inhibition was accompanied by the changes in the ER morphology. These results indicate the accumulation of misfolded proteins in the ER-lumen, due to an interruption in N-glycosylation of proteins. Thus, it is obvious that the process of N-glycosylation is necessary for the normal growth and development of flax seedlings, and the plant phenotype will be determined by a change in the status of N-glycosylation of specific glycoproteins.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.
