Summary: By studying three cv. Malbec clones cultivated in two vineyards with contrasting environmental conditions, it was demonstrated that DNA methylation plays a crucial role in phenotypic plasticity and that epigenetic modulation is dependent on the specific clone. Environmental signals can induce epigenetic changes that alter gene expression and phenotype. DNA methylation has been identified as a key mechanism underlying phenotypic variability in grapevines, with clone-dependent effects observed.

Summary: The shift in grape harvest timing from wet summer to dry winter in Southeast Brazil through double-pruning management has led to an improvement in the quality of winter wines. Differences in vineyard vigor were more related to management practices, while grape quality in terms of sugar and acidity was influenced by soil sand content and winter temperature. Overall, the high thermal range and low precipitation during autumn-winter were found to be the main factors contributing to the improvement of phenolic compounds in grapes.

Summary: Recent studies have shown that moderate iron stress can increase the concentrations of volatile organic compounds associated with floral notes in wines, while decreasing the presence of C6-alcohols responsible for green herbaceous aromas. Wines from iron deficient subzones showed a favorable reduction in pH and improvements in color-related parameters. The incidence of chlorosis was associated with enhancements in wine sensory attributes such as layer intensity, black fruit, and aroma intensity.

Summary: The high-altitude viticulture in Mendoza is gaining recognition worldwide due to its high levels of solar ultraviolet-B radiation, alluvial heterogeneous soils, and cool night temperatures. This study evaluated the impact of contrasting soil depth on the physiological traits, yield components, and berry skin phenolic compounds of Malbec grapes. The results showed that root depth was not limited by soil physical constraints, and shallow soils had higher root quantity but lower vegetative and reproductive expressions compared to deep soils. Additionally, mild water stress in shallow soils led to increased anthocyanins, total polyphenols, and antioxidant capacity in berry skins.

Summary: This study investigates the stability of PCs in grape canes extracts under different storage temperatures and light conditions. The composition of PCs was analyzed every two weeks using LC-DAD-FLD. Stilbenes initially accounted for 87% of total PCs. Storage at -20 and 5 degrees C resulted in a reduction of 8% and 6% in PCs, respectively. Higher temperatures and light exposure accelerated the degradation of certain PCs, such as (+)-catechin and (-)-epicatechin. trans-piceatannol was particularly sensitive to temperature increase, while the degradation of trans-resveratrol and epsilon-viniferin was mostly catalyzed by light.

Summary: DNA methylation is a key epigenetic mark that plays a role in gene silencing and transposable elements' (TEs) repression. It varies significantly throughout the plant life cycle, but is efficiently reinforced during reproduction to maintain stable TE silencing. Plant reproduction can occur through different modes, including asexual propagation, which bypasses critical reinforcement steps. This review summarizes recent progress in understanding DNA methylation inheritance in sexual and asexual plants. It suggests that the methylomes of asexual seeds should resemble those of sexual counterparts, whereas clonally propagated plants are expected to have hypomethylated genomes with frequent stochastic epigenetic changes. The use of nonmodel organisms holds promise for advancing our knowledge of epigenetic inheritance in plants.

Summary: DNA methylation in plant genomes can provide genealogical information at short time scales, but its reliability at micro-evolutionary time scales is unclear due to meta-stability and environmental effects. In a study of common dandelion, differentially methylated cytosines (DMCs) were induced by light treatment, with genetic divergence between accessions correlating strongly with overall methylation profiles. However, environmental effects may partly dilute the genealogical signal in CG context. Methylation information can be used to reconstruct micro-evolutionary genealogy in plants lacking genetic variation.

Summary: The present study characterized a diverse collection of purple and non-purple carrot accessions for their concentration of anthocyanins, phenolics, carotenoids, and antioxidant capacity. Significant variation was found among the accessions, with acylated anthocyanins being the most dominant pigment. Purple carrots exhibited higher levels of anthocyanins, phenolics, and antioxidant capacity compared to non-purple carrots. Antioxidant capacity was positively correlated with anthocyanin content and total phenolic content, but not with carotenoids. Certain accessions were identified as potential sources for food dyes or increased nutraceutical value.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.
