How to make almonds palatable The domesticated almond tree has been feeding humans for millennia. Derivation from the wild, bitter, and toxic required loss of cyanogenic diglucoside amygdalin. Sánchez-Pérez et al. sequenced genome analyzed genomic region responsible this shift. key change turned out be a point mutation in transcription factor that regulates production P450 monooxygenases biosynthetic pathway compound.

Cyanogenic glycosides are phytoanticipins involved in plant defence against herbivores by virtue of their ability to release toxic hydrogen cyanide (HCN) upon tissue disruption. In addition, endogenous turnover cyanogenic without the liberation HCN may offer plants an important source reduced nitrogen at specific developmental stages. To investigate presence putative products glycosides, comparative metabolic profiling using LC–MS/MS and high resolution MS (HR–MS) complemented ion-mobility...

Release of bud dormancy in perennial woody plants is a temperature-dependent process and thus flowering these species heavily affected by climate change. The lack cold winters temperate growing regions often results reduced low fruit yields. This likely to decrease the availability fruits nuts Prunus spp. near future. In order maintain high yields, it crucial gain detailed knowledge on molecular mechanisms controlling release dormancy. Here, we studied using sweet cherry (Prunus avium L.),...

Bitterness in almond (Prunus dulcis) is determined by the content of cyanogenic diglucoside amygdalin. The ability to synthesize and degrade prunasin amygdalin kernel was studied throughout growth season using four different genotypes for bitterness. Liquid chromatography-mass spectrometry analyses showed a specific developmentally dependent accumulation tegument bitter genotype. level decreased concomitant with initiation cotyledons By administration radiolabeled phenylalanine, identified...

Abstract Six tree traits (self‐compatibility, blooming date, density, productivity, leafing date and ripening time) five pomological (kernel taste, in‐shell weight, shell hardness, kernel weight double kernel) were studied in an F 1 almond progeny of 167 seedlings from the cross between French cultivar ‘R1000’ Spanish ‘Desmayo Largueta’. In addition, a set 135 codominant microsatellites or simple‐sequence repeat (SSR) markers developed peach, cherry used for molecular characterization...

Almond (Prunus dulcis) is the principal Prunus species in which consumed and thus commercially important part of fruit kernel. As a result continued selection, vast majority almonds have nonbitter However, field, there are trees carrying bitter kernels, toxic to humans and, consequently, need be removed. The toxicity caused by accumulation cyanogenic diglucoside amygdalin, releases hydrogen cyanide upon hydrolysis. In this study, we identified characterized enzymes involved amygdalin...

The lack of robust, high-throughput, and sensitive analytical strategies that can conclusively map the structure glycans has significantly hampered progress in fundamental applied aspects glycoscience. Resolution anomeric α/β glycan linkage within oligosaccharides remains a particular challenge. Here, we show "memory" configuration is retained following gas-phase glycosidic bond fragmentation during tandem mass spectrometry (MS2). These findings allow for integration MS2 with ion mobility...

Almond and sweet cherry are two economically important species of the Prunus genus. They both produce cyanogenic glucosides prunasin amygdalin. As part a two-component defense system, amygdalin release toxic hydrogen cyanide upon cell disruption. In this study, we investigated potential role some its derivatives in endodormancy these species. The content endogenous turnover products course flower development/opening was examined five almond cultivars – differing from very early to extra-late...

Abstract Flower bud dormancy in temperate fruit tree species, such as almond [Prunus dulcis (Mill.) D.A. Webb], is a survival mechanism that ensures flowering will occur under suitable weather conditions for successful flower development, pollination and set. Dormancy divided into three sequential phases: paradormancy, endodormancy ecodormancy. During the winter, buds need cultivar-specific chilling requirements (CRs) to overcome heat activate machinery ecodormancy phase. One of main factors...

Abstract Temperate fruit trees belonging to Prunus species have the ability suspend (induce dormancy) and resume growth periodically in response environmental seasonal conditions. Endodormancy release requires long-term accumulation of chill. Upon cultivar-specific chill requirements, plants enter state ecodormancy, which means grow has been restored, depending on fulfilment heat requirements. As many different metabolic pathways are implicated endodormancy release, we performed a...

Introduction In Mediterranean areas like Spain, global warming has endangered stone fruit production by reducing chill accumulation, leading to significant agronomical and economical losses. To mitigate this issue, agrochemicals have been applied for decades promote endodormancy release initiate flowering. However, many of these chemicals associated with strong phytotoxicity, resulting in their recent ban. As a result, identifying novel pathways modulate is critical essential developing...

Abstract Almond [ Prunus dulcis Miller (D.A. Webb)] is the main tree nut species worldwide. Here, genotyping-by-sequencing (GBS) was applied to 149 almond cultivars from ex situ collections of Italian Council for Agricultural Research (CREA) and Spanish National (CSIC), leading detection 93,119 single-nucleotide polymorphisms (SNPs). The study population structure outlined four distinct genetic groups highlighted diversification between Mediterranean Californian gene pools. Data on SNP...
