“…PME has been implicated in different developmental processes such as cellular adhesion (Jarvis, Briggs & Knox 2003; Sobry, Havelange & Van Cutsem 2005) and separation (Wen, Zhu & Hawes 1999), leaf growth polarity (Hasunuma, Fukusaki & Kobayashi 2004), root tip elongation (Pilling et al. 2004), internode stem growth (Saher et al. 2005) and fruit ripening (Phan et al.…”

In a variety of herbaceous, model and crop plants, DL-baminobutyric acid (BABA), has been shown to enhance both biotic and abiotic stress resistance by potentiating rather than inducing resistance responses but studies in woody plants are lacking. In the present study, twodimensional difference in-gel electrophoresis (DIGE) was used to quantify differences in protein abundance in leaf tissue from BABA-treated, abscisic acid (ABA)-treated and untreated (control) plants during a 10 d drought stress. ABA-treated seedlings were most resistant to water loss followed by BABA-treated seedlings and then untreated seedlings. Although some similarity was observed in the proteome of ABA-and BABA-treated seedlings, a dramatic shift in the proteome occurred earlier in ABA-treated seedlings. Some proteins showed almost identical patterns of increase or decrease in abundance in both BABAand ABA-treated seedlings, supporting the concept that BABA-induced abiotic stress resistance in plants is achieved by potentiating an ABA-regulated pathway. Some proteins, however, were induced or suppressed only in BABA-primed plants, indicating that BABA may also mediate resistance via some ABA-independent pathways. Based on the putative function of the identified proteins, we propose that changes in cell wall enzymes and a suppression of lignin biosynthesis may play a specific role in BABAprimed drought resistance.

“…Several lines of evidence suggest that pectins are responsible for the strength of intercellular attachments, which in turn might be related to tissue compactness and morphogenetic properties (Bouton et al 2002, Brummell et al 2004, Liners et al 1994, Malinowski and Filipecki 2002, Saher et al 2005, Sobry et al 2005. Similarly, the structure of other cell wall oligosaccharides has been shown to determine their biological activity in terms of cells or organs growth (Kollárová et al 2006).…”

Cell wall composition in leaves and regenerating leaf-derived protoplasts was studied in Beta vulgaris L. and Nicotiana tabacum L. Several oligosaccharides that characterize arabinogalactan proteins (AGPs) and pectins were visualized in situ by a series of immunocytochemical reactions. The most conspicuous difference between the two species involved the expression of AGP epitopes that bind LM2 and MAC207 in only sugar beet cells; both epitopes being characterized by the presence of glucuronic acid (GlcA). Moreover, B. vulgaris leaves and protoplast-derived cells showed lower content of pectin side-chains bearing (1→4)-β-D-galactose residues as compared to N. tabacum.

“…Saher et al (2005aSaher et al ( , 2005b) studied a mechanism of hyperhydricity, discovering that different pectin methyl esterase (PME) activities influence structural changes related to hyperhydricity in micropropagated carnation plants. Hyperhydric leaves of carnations adapted to hypoxia stress conditions through both oxidative pentose phosphate and fermentative pathway induction.…”

An efficient protocol was established for Sedum spectabile Boreau propagation. Various leaf parts were used as explants to regenerate plantlets, the stem segments of which were cultured for shoot proliferation and plantlet multiplication. The results showed that the leaf base was the optimal explant, as compared to both the middle and the top of leaves, for shoot formation. The highest shoot induction of 88.9% was observed on MS medium supplemented with 0.6 mg/l TDZ and 0.1 mg/l NAA. Hyperhydric leaves obtained in primary culture developed first into abnormal somatic embryos 10 days after subculture, and then into hyperhydric plantlets after an additional 10 days. The hyperhydric plantlets reversed to normal plantlets when plant growth regulators were removed from culture medium. Further, stem segments from reversed plantlets were used for shoot regeneration and root induction. Optimal shoot regeneration was obtained in MS medium containing 0.6 mg/l TDZ with 0.1 mg/l NAA. Root induction and root mean number were all higher on auxin-free medium than on medium containing auxins.
