“…Conversely, Reuveni et al (1993) indicated that variation in other medium components including high levels of cytokinins did not directly affect the rate of somaclonal variation in 'Cavendish' bananas, instead the main effect was that of genotype. Leaf-colour variants observed in somaclones of Caladium varied with auxin type more than with concentration of specific auxins.…”

“…The reviews however, have limitations in that they deal with specific aspect(s) of somaclonal variation (Lee and Phillips 1988;Bajaj 1990;Karp 1994), specific species of plants (Reuveni et al 1993;Sahijram et al 2003) or specific application(s) of somaclonal variation (Larkin and Scowcroft 1981;Karp 1995;Kaeppler et al 2000;Jain 2001). To the best of our knowledge, there is no review on somaclonal variation that puts together the causes and detection methods in combination with a comprehensive list of practical examples (Table 1).…”

Somaclonal variation in plants: causes and detection methods

Plant tissue culture has become one of the fundamental tools of plant science research. It is extensively employed in the production, conservation and improvement of plant resources. The presence of somaclonal variation in populations derived from tissue culture is affecting the use of tissue culture negatively and has remained a major problem. Conversely, it is a source of new desirable clones/variants with better agronomic traits. In this review, we summarize the possible causes, detection methods and desirability of variants. Somaclonal variation is one of the most researched and reviewed topics. Hence, we restricted ourselves to outlining various examples which may be used as important references for researchers who intend to identify and/or characterize somaclonal variants while using tissue culture for research and production. Emphasis is placed on the negative effects of somaclonal variation. However, this review also includes examples of some useful variants generated as a result of somaclonal variation.

“…Lignin and phenol are synthesized via phenyl propanoid pathways which impart resistance against nematode attack. The role of phytoalexins and other toxic compounds like phenols and lignin in resistance mechanism have been reported by earlier workers (Reuveni et al, 1992 andSariah et al, 1999). An increase in the number of lignified cells in tolerant cultivars compared to susceptible cultivars of banana was noted by Fogain, (1996) and Kavino et al, (2007).…”

“…Lignin and phenol are synthesized via phenyl propanoid pathway which impart resistance against nematode attack. The role of phytoalexins and other toxic compounds like phenols and lignin (which are otherwise called phytoanticipins and are synthesized as a part of the normal plant development) in resistance mechanism have been reported by earlier workers (Reuveni et al, 1992;Sariah et al, 1999).…”

Investigations were carried out to screen the in vitro derived mutants of banana cv. Robusta (Caveidish-AAA) and Rasthali (Silk-AAB) by using certain bio-chemical parameters including some enzyme activities. The mutants tested were Ro Im V 4 6-1-1, Ro Im V 4 6-1-2, Ro Im V 4 6-2-1, Si Im V 4 10-5-3, Si Im V 4 6-2-5 along with respective susceptible checks (Robusta and Rasthali), tolerant check (Anaikomban-AA) and resistant check (Pisang Lilin-AA). Various biochemical assays used were total phenol, tannin content, lignin content, peroxidase, polyphenol oxidase, phenyl alanine ammonia lyase and ascorbic acid oxidase. The results revealed that the mutants namely Ro Im V 4 6-1-1 and Si Im V 4 10-5-3 were found to be resistant while the mutant Ro Im V 4 6-2-1 was moderately resistant. The rest of the mutants namely Ro Im V 4 6-1-2 and Si Im V 4 6-2-5 were found to be susceptible to nematodes. The resistant and moderately resistant mutants of banana could be further used in breeding programmes as well as being recognized as potential cultivars of commerce.
