“…The disorder did not seem to be related with endogenous cytokinin levels (Jones et al 1995). As this is typically a homeotic change, alterations in the homeotic genes that participate in the determination of floral organ identity should be considered (Alwee et al 2006). Almost all of these are members of the MADS box transcription factor family.…”

Plants produced vegetatively in tissue culture may differ from the plants from which they have been derived. Two major classes of off-types occur: genetic ones and epigenetic ones. This review is about epigenetic aberrations. We discuss recent studies that have uncovered epigenetic modifications at the molecular level, viz., changes in DNA methylation and alterations of histone methylation or acetylation. Various studies have been carried out with animals, and with plant cells or tissues that have grown in tissue culture but only little work has been done with shoots generated by axillary branching. We present various molecular methods that are being used to measure epigenetic variation. In micropropagated plants mostly differences in DNA methylation have been examined. Epigenetic changes are thought to underlie various well-known tissue-culture phenomena including rejuvenation, habituation, and morphological changes such as flower abnormalities, bushiness, and tumorous outgrowths in, among others, oil palm, gerbera, Zantedeschia and rhododendron.

“…Plants that have been generated in this way, may show an aberration in their flowers, referred to as 'mantled'. These flowers develop a second whorl of carpels instead of stamens (Alwee et al 2006). Most often the fruit does not develop properly (Corley et al 1986) (Fig.…”

“…In plants, increasing evidence suggests that MADS-box genes play crucial roles in the processes of flowering plant growth, which influence flowering time (i.e. genes such as SOC1, FLC and SVP), formation and meristem identity of floral organs (AP1, FUL and AG), fruit ripening (SHP1 and SHP2), seed pigmentation and embryo development (TRANSPARENT TESTA16) (Alwee et al 2006;Samach et al 2000;Michaels and Amasino 1999;Hartmann et al 2000;Mandel et al 1992;Gu et al 1998;Liljegren et al 2000;Nesi et al 2002;Parenicova et al 2003;Arora et al 2007).…”

MADS-box genes comprise a large gene family, which codes for transcription factors, and play important functions in various aspects of flowering plant growth and development. However, little is known about the MADS-box genes in maize (Zea mays) and sorghum (Sorghum bicolor). Here, we performed a comprehensive bioinformatics analysis of the MADS-box gene family in the maize and sorghum genomes and identified 75 maize and 65 sorghum MADS-box genes. We subsequently carried out a comparative analysis of these genes, including the gene structure, phylogenetic relationship, conserved protein motifs, gene duplications, chromosomal locations and expression pattern between the two plants. According to these analyses, the MADS-box genes in both maize and sorghum were categorized into five (MIKC C , MIKC*, Ma, Mb and Mc) groups, and the MIKC C groups were further divided into 11 subfamilies. In addition, gene duplications of MADS-box genes were also investigated in the maize, sorghum, rice and Arabidopsis genomes. We found a higher percentage of MADS-box gene duplications in the maize and sorghum genomes, which contributed to the expansion of the MADS-box gene family. Furthermore, both tandem and segmental duplications played a major role in the MADS-box gene expansion in maize and sorghum. A survey of maize and sorghum EST sequences indicated that MADS-box genes exhibit a various expression pattern, suggesting diverse and novel functions of MADS-box gene families in the two plants. These results provided a useful reference for selection of candidate MADS-box genes for cloning and further functional analysis in both maize and sorghum.

“…Therefore, the cost, time and labour spent on production constitute huge losses. The abnormality is characterized by: 1) Flowers with ''mantled'' character (Plates 1 and 2); that is, flowers develop a secondary carpel whorl instead of stamen (apparent feminization of male parts in flowers of both sexes) (Corley et al, 1986;Alwee et al, 2006;Jaligot et al, 2000).…”

Somaclonal variation refers to any phenotypic or genotypic modifications that arise from in vitro culture. In the oil palm, it is characterized by fruit mantling and abnormal vegetative growth. Tissue culture remains the only means of micro propagation of oil palm as its biological characteristics do not allow for vegetative propagation by conventional means. The early success of plantlets production inspired many oil palm organizations to explore in vitro propagation technique. Though oil palm tissue culture is already well established, it is still faced with many challenges. Prominent among them is somaclonal variation which was first reported in 1986. They are only detectable when the palms start flowering; that is, after two to three years in the field. It has not been possible to fully eliminate or circumvent floral abnormality in the oil palm. However, the adoption of several measures such as reducing hormone level, avoiding fast growing callus and, reducing culture period, have reduced the problem to manageable levels of < 5%. Possible causes and factors influencing somaclonal variation in the oil palm are discussed.
