Fine Mapping of the "black" Peel Color in Pomegranate ( L.) Strongly Suggests That a Mutation in the () Gene Is Responsible for the Trait.

Anthocyanins are important dietary and health-promoting substances present in high quantities in the peel and arils of the pomegranate ( L.) fruit. Yet, there is a high variation in the content of anthocyanin among different pomegranate varieties.

Primary Metabolites, Anthocyanins, and Hydrolyzable Tannins in the Pomegranate Fruit.

Pomegranate ( L.) is an important and interesting fruit tree that is cultivated in many parts of the world. In recent years, along with the increase in its cultivation and consumption there has been a dramatic increase in the scientific interest in its biology, methods of cultivation, adaptation to environmental cues and its health-promoting properties.

Diversity among Pomegranate Varieties in Chilling Tolerance and Transcriptome Responses to Cold Storage.

We found great variability in chilling tolerance among 84 pomegranate varieties from the Newe Ya'ar collection; among them, 'Ganesh' was chilling-sensitive, whereas 'Wonderful' was relatively chilling-tolerant. To evaluate the different molecular responses of these varieties to cold storage, we analyzed the transcriptomic changes in the inner membrane tissues of 'Ganesh' and 'Wonderful' fruit after 2 weeks of cold storage at 1 °C. By functional categorization of the differentially expressed transcripts using MapMan, we found that many transcripts related to various pathways, such as jasmonic acid biosynthesis and signaling, galactinol, raffinose, phenol, and phenylpropanoid biosynthesis, calcium and mitogen-activated protein kinase signaling, lipid metabolism, and various transcription factors and heat-shock proteins, have been massively upregulated in 'Wonderful' but not in 'Ganesh' fruit.

Grafting on resistant interstocks reduces scion susceptibility to pear psylla, Cacopsylla bidens.

Background: Pear psylla is a major obstacle to efficient integrated pest management in pear orchards in Israel and around the world. We used two accessions with natural resistance to pear psylla Cacopsylla bidens (Šulc) - Py.760-261 (760) and Py.

A "White" Anthocyanin-less Pomegranate (Punica granatum L.) Caused by an Insertion in the Coding Region of the Leucoanthocyanidin Dioxygenase (LDOX; ANS) Gene.

Color is an important determinant of pomegranate fruit quality and commercial value. To understand the genetic factors controlling color in pomegranate, chemical, molecular and genetic characterization of a "white" pomegranate was performed. This unique accession is lacking the typical pomegranate color rendered by anthocyanins in all tissues of the plant, including flowers, fruit (skin and arils) and leaves.

Single-nucleotide polymorphism markers from de-novo assembly of the pomegranate transcriptome reveal germplasm genetic diversity.

Pomegranate is a valuable crop that is grown commercially in many parts of the world. Wild species have been reported from India, Turkmenistan and Socotra. Pomegranate fruit has a variety of health-beneficial qualities.

Two pear accessions evaluated for susceptibility to pear psylla Cacopsylla bidens (Šulc) in Israel.

Background: The pear psylla, Cacopsylla bidens (Šulc), is one of the most damaging pests of commercial pear orchards in Israel. Psylla control is a major obstacle to efficient integrated pest management, necessitating research on cultivars with natural resistance to pear psylla. Recently, two pear accessions (Py.

A pomegranate (Punica granatum L.) WD40-repeat gene is a functional homologue of Arabidopsis TTG1 and is involved in the regulation of anthocyanin biosynthesis during pomegranate fruit development.

Anthocyanins are the major pigments responsible for the pomegranate (Punica granatum L.) fruit skin color. The high variability in fruit external color in pomegranate cultivars reflects variations in anthocyanin composition.

Climate effects on anthocyanin accumulation and composition in the pomegranate (Punica granatum L.) fruit arils.

Worldwide pomegranate (Punica granatum L.) production has expanded greatly due to recent evidence on the fruit health attributes. The fruit's unique red color, conferred by anthocyanins, is an imperative sensory quality.

Environmental conditions affect the color, taste, and antioxidant capacity of 11 pomegranate accessions' fruits.

The well-established health beneficial value of pomegranate juice is leading to increased demand for pomegranate products and to the expansion of pomegranate orchards worldwide. The current study describes differences in the chemical composition of major ingredients of the arils and peels of 11 accessions grown in Mediterranean and desert climates in Israel. In most of the accessions, the levels of antioxidant activity and content of total phenolics, total anthocyanins, total soluble solids, glucose, fructose, and acidity were higher in the aril juice of fruit grown in the Mediterranean climate compared to those grown in the desert climate.

Developmental and varietal differences in volatile ester formation and acetyl-CoA: alcohol acetyl transferase activities in apple (Malus domestica Borkh.) fruit.

Apple (Malus domestica Borkh.) cultivars differ in their aroma and composition of volatile acetates in their fruit flesh and peel. Cv.
