“…Since flavonols are important for fruit cuticle biomechanics and postharvest behavior (Domínguez et al, 2009a(Domínguez et al, , 2011Lara et al, 2014), we investigated whether some of the genes differentially expressed in the Dy mutants might be involved in cuticle development. Of these 267 genes, we identified a set of 18 in the biosynthesis of cutin monomers, cuticular waxes (i.e.…”

“…There is interest in flavonoids due to their effect on fruit appearance and their nutritional and healthrelated properties (Rein et al, 2006;Butelli et al, 2008;Luo et al, 2008;Martin et al, 2011). In tomato fruit, they have also been reported to contribute to correct cuticle function as they affect its rigidity and susceptibility to cracking and, consequently, postharvest behavior (Domínguez et al, 2009a(Domínguez et al, , 2011Lara et al, 2014). Increasing the accumulation, or compositional diversity, of polyphenol species, including flavonoids, to improve fruit nutritional value and tolerance to environmental stress, is an important goal of biotechnology and breeding Zhang et al, 2015).…”

Characterization of a New Pink-Fruited Tomato Mutant Results in the Identification of a Null Allele of the SlMYB12 Transcription Factor

The identification and characterization of new tomato (Solanum lycopersicum) mutants affected in fruit pigmentation and nutritional content can provide valuable insights into the underlying biology, as well as a source of new alleles for breeding programs. To date, all characterized pink-pigmented tomato fruit mutants appear to result from low SlMYB12 transcript levels in the fruit skin. Two new mutant lines displaying a pink fruit phenotype (pf1 and pf2) were characterized in this study. In the pf mutants, SlMYB12 transcripts accumulated to wild-type levels but exhibited the same truncation, which resulted in the absence of the essential MYB activation domain coding region. Allelism and complementation tests revealed that both pf mutants were allelic to the y locus and showed the same recessive null allele in homozygosis: Dy. A set of molecular and metabolic effects, reminiscent of those observed in the Arabidopsis (Arabidopsis thaliana) myb11 myb12 myb111 triple mutant, were found in the tomato Dy mutants. To our knowledge, these have not been described previously, and our data support the idea of their being null mutants, in contrast to previously described transcriptional hypomorphic pink fruit lines. We detected a reduction in the expression of several flavonol glycosides and some associated glycosyl transferases. Transcriptome analysis further revealed that the effects of the pf mutations extended beyond the flavonoid pathway into the interface between primary and secondary metabolism. Finally, screening for Myb-binding sites in the candidate gene promoter sequences revealed that 141 of the 152 co-down-regulated genes may be direct targets of SlMYB12 regulation.

“…The presence of triterpenoids in the surface layer is of interest due to their potential role in the protection against biotic stresses, and in the case of fruits -in the modulation of the mechanical toughness and the post-harvest quality [16,17]. It is commonly assumed that the protection against water loss is not a primary function of triterpenoid constituent.…”

Triterpenoid profile of fruit and leaf cuticular waxes of edible honeysuckle Lonicera caerulea var. kamtschatica

Edible honeysuckle (honeyberry) Lonicera caerulea is becoming popular as a novel berry crop with several useful features such as early fruit ripening and exceptional hardiness, particularly resistance to pests and diseases as well as severe frosts in winter and droughts in summer. The triterpenoid profile of fruit and leaf cuticular waxes of edible honeysuckle (a Russian cultivar Chernichka) was analyzed by GC-MS. The major compounds identified were the tetracyclic triterpenoids campesterol, cholesterol, cycloartanol, cycloart-23-ene-3,25-diol, 24-methylenecycloartanol (only in leaves), sitosterol, stigmasta-3,5-dien-7-one, and stigmasterol; and the pentacyclic triterpenes: α-amyrin, β-amyrin, hop-22(29)-en-3-one, oleanolic acid, and ursolic acid. Several remarkable features of the analyzed triterpenoid contents were revealed, including the relatively low abundance of triterpenoids in fruit waxes (6.5% of wax extract) compared to leaf waxes (22%), and a particularly high proportion of tetracyclic triterpenoids (tetracyclic to pentacyclic compound ratios of 4:1 in fruits and almost 7:1 in leaves). These rare features distinguish the triterpenoid profile of the cuticular waxes of L. caerulea var. kamtschatica from the majority of triterpenoid profiles in plant cuticular waxes investigated to date. To our knowledge, this is the first quantitative compositional study on triterpenoid compounds in the cuticular waxes of edible honeysuckle, supplementing the knowledge of cuticular triterpenoid diversity and distribution.

The environment in which the fruit of avocado (Persea americana Mill.) cv. Hass determines the characteristics of your skin which represents the first natural barrier and the tissue that interacts directly with the environment. The fruit is exposed to many types of stress and to protect itself produces a wide variety of phytochemicals, called secondary metabolites. It is unknown if aspects such as nutritional composition and skin morphology could also be affected. The study was carried out in commercial Avocado "Hass" orchards with the standard management of each producer in order to determine phytochemical concentrations (total phenolics, total chlorophylls, total carotenoids and lignin) and nutrients (N, P, K, Ca, Mg, S, Fe, Cu, Mn, Zn and B), and to establish their relationship with the roughness of the fruit skin during its development in three regions with different types of climate. The type of climate (warm, semi-warm or temperate) influenced the production of phytochemicals and the roughness of 'Hass'skin. The global analysis showed that the fruits of the warm climate presented the highest concentration of total carotenoids and greater roughness, while in the temperate climate, the roughness was lower.
