Significant Findings: 1. Apple leaf quality deteriorates with the season. We confirmed in multiple seasons that L. subjuncta larval development is prolonged and pupal weight is decreased on apple foliage as the season progresses. These data indicate the apple leaves are a relatively good food material for Lacanobia larvae early in the season but deteriorate in quality later in the season. Simil...

The gibberellins 'have ibeen established as effective fruit setting agents (5). In the apple, where auxins are generallly inactive, the gi'bberellins induce parthenocarpy and sustain fruit growth to maturity (2,6, 10). This pronounced fruit-setting activity and the estafblished observation that asymmetric growtth of apple fruit is related to incomplete seed development, -has encouraged investig...

The cashew tree (Anacardium occidentale L.) belongs to the family Anacardiaceae. It is a native plant of Brazil. The fruit consists of a cashew nut (the true fruit) and a cashew apple (pseudofruit). The cashew nut is the most important product of the cashew tree; whereas the cashew apple has increased in value [1]. Many procedures have been industrialized for transforming the cashew apple into ...

BACKGROUND AND AIMS Fruit ripening in Malus× domestica (apple) is controlled by ethylene. Work in model species has shown that following the detection of ethylene, the ETHYLENE INSENSITIVE 3 (EIN3) transcription factor is stabilized, leading to an increase in transcript accumulation of ethylene-responsive genes, such as POLYGALACTURONASE1 (PG1). In the absence of ethylene, the EIN3 BINDING F-bo...

Apple is one of the most economically important horticultural fruit crops worldwide. It is critical to gain insights into fruit ripening and softening to improve apple fruit quality and extend shelf life. In this study, forward and reverse suppression subtractive hybridization libraries were generated from 'Taishanzaoxia' apple fruits sampled around the ethylene climacteric to isolate ripening-...

Cardiovascular disease (CVD) is the leading cause of death worldwide. There is a consistent inverse relationship between fruit intake with CVD events and mortality in cross-sectional and prospective observational studies, but the relationship of fruit intake with measurements of atherosclerosis in humans is less clear. Nutritional effects on abdominal aortic calcification (AAC), a marker for su...

Fruit size regulation was studied in the apple cultivar 'Gala' and a large fruit size spontaneous mutant of 'Gala', 'Grand Gala' (GG). GG fruits were 15% larger in diameter and 38% heavier than 'Gala' fruits, largely due to an increase in size of the fruit cortex. The mutation in GG altered growth prior to fruit set and during fruit development. Prior to fruit set, the carpel/floral-tube size w...

Apple fruit are well known for their storage life, although a wide range of flesh softening occurs among cultivars. Loss of firmness is genetically coordinated by the action of several cell wall enzymes, including polygalacturonase (PG) which depolymerizes cell wall pectin. By the analysis of 'Fuji' (Fj) and 'Mondial Gala' (MG), two apple cultivars characterized by a distinctive ripening behavi...

Apple ( X Borkh.) is one of the world's most valuable fruit crops. Its large size and long juvenile phase make it a particularly promising candidate for marker-assisted selection (MAS). However, advances in MAS in apple have been limited by a lack of phenotype and genotype data from sufficiently large samples. To establish genotype-phenotype relationships and advance MAS in apple, we extracted ...

Carotenoid accumulation confers distinct colouration to plant tissues, with effects on plant response to light and as well as health benefits for consumers of plant products. The carotenoid pathway is controlled by flux of metabolites, rate-limiting enzyme steps, feed-back inhibition, and the strength of sink organelles, the plastids, in the cell. In apple (Malus × domestica Borkh), fruit carot...
