Open AccessMetabolic changes in pomegranate fruit skin following cold storage promote chilling injury of the peel
Pomegranate cv. ‘Wonderful’ fruit are susceptible to chilling injuries of the peel (CIp) when stored at 7 °C in modified-atmosphere bags for more than 3 months. The damage, manifested as superficial browning, ...

Open AccessThe transcriptome of potato tuber phellogen reveals cellular functions of cork cambium and genes involved in periderm formation and maturation
The periderm is a protective corky tissue that is formed through the cambial activity of phellogen cells, when the outer epidermis is damaged. Timely periderm formation is critical to prevent pathogen invasion...

Nutritional value of potato (Solanum tuberosum) in hot climates: anthocyanins, carotenoids, and steroidal glycoalkaloids
Growth in hot climates selectively alters potato tuber secondary metabolism—such as the anthocyanins, carotenoids, and glycoalkaloids—changing its nutritive value and the composition of health-promoting compon...

Lanosterol synthase-like is involved with differential accumulation of steroidal glycoalkaloids in potato
Phytosterol homeostasis may be maintained in leaves through diversion of intermediates into glycoalkaloid biosynthesis, whereas in tuber flesh, excess intermediates are catalyzed by tu...

Benzyladenine and gibberellin treatment of develo** “Pink Lady” apples results in mature fruits with a thicker cuticle comprising clusters of epidermal cells
A mixture of 6-benzyladenine (BA) and gibberellins GA4 plus GA7 applied to “Pink Lady” apple at early phenological stages was previously shown to result in an immediate increase in epidermal cell density and asso...

Induction of potato steroidal glycoalkaloid biosynthetic pathway by overexpression of cDNA encoding primary metabolism HMG-CoA reductase and squalene synthase
Potato steroidal glycoalkaloids (SGAs) are toxic secondary metabolites whose total content in tubers must be regulated. SGAs are biosynthesized by the sterol branch of the mevalonic acid/isoprenoid pathway. In...

Potato Steroidal Glycoalkaloids: Biosynthesis and Genetic Manipulation
The potato steroidal glycoalkaloids (SGAs) are important components of plant resistance against pests and pathogens but can be toxic to humans at high levels. SGAs derive their toxicity from anticholinesterase...

Potato steroidal glycoalkaloid levels and the expression of key isoprenoid metabolic genes
The potato steroidal glycoalkaloids (SGA) are toxic secondary metabolites, and their total content in tubers should not exceed 20 mg/100 g fresh weight. The two major SGA in cultivated potato (Solanum tuberosum) ...

Isolation and characterization of two different cDNAs of Δ1-pyrroline-5-carboxylate synthase in alfalfa, transcriptionally induced upon salt stress
Two different cDNA clones, MsP5CS-1 and MsP5CS-2, encoding Δ1-pyrroline-5-carboxylate synthase (P5CS), the first enzyme of the proline biosynthetic pathway, were isolated from a λZap-cDNA library constructed f...
