In this study, we investigated seed and auxin regulation of gibberellin (GA) biosynthesis in pea (Pisum sativum L.) pericarp tissue in situ, specifically the conversion of [14C]GA19 to [14C]GA20. [14C]GA19 metabolism was monitored in pericarp with seeds, deseeded pericarp, and deseeded pericarp treated with 4-chloroindole-3-acetic acid (4-CI-IAA). Pericarp with seeds and deseeded pericarp treat...

UNLABELLED The characteristics of tomato pericarp are closely associated with peelabililty, an important quality attribute of processing tomatoes. Different types of tissue exist in the pericarp of tomato. The outermost region of the pericarp, the red layer, is removed with the skin during peeling. This study investigated the morphological features and tissue properties of red layer and pericar...

Polyphenol oxidase (PPO) plays a key role in the postharvest pericarp browning of litchi fruit, but its underlying mechanism remains unclear. In this study, we cloned the litchi PPO gene (LcPPO, JF926153), and described its expression patterns. The LcPPO cDNA sequence was 2120 bps in length with an open reading frame (ORF) of 1800 bps. The ORF encoded a polypeptide with 599 amino acid residues,...

The tomato fruit consists of a thick, fleshy pericarp composed predominantly of highly vacuolated parenchymatous cells, which surrounds the seeds. During ripening, the activation of gene expression results in dramatic biochemical and physiological changes in the pericarp. The polygalacturonase (PG) gene, unlike many fruit ripening-induced genes, is not activated by the increase in ethylene horm...

Phenolics were extracted from litchi fruit pericarp (LFP) tissues, purified and their antioxidant properties analyzed. LFP phenolics strongly inhibited linoleic acid oxidation and exhibited a dose-dependent free-radical scavenging activity against alpha,alpha-diphenyl-beta-picrylhydrazyl (DPPH*) and hydroxyl radicals and superoxide anions. The degradation of deoxyribose by hydroxyl radicals was...

The tensile force existing in the pericarp of a growing citrus (Citrus sinensis) fruit 17 to 19 centimeters in circumference was sufficiently high to cause a 3% shrinkage of the pericarp when it was excised. When a fruit was cut along the equator to the central axis, shrinkage of the pericarp resulted in the formation of a wedge-shaped gap at the cut. Stretch modulus of the pericarp was determi...

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. The α-mangostin in mangosteen pericarp extract can inhibit M. tuberculosis growth. This study examined the potency of α-mangostin in mangosteen pericarp extract to inhibit 38-kDa and Ag85 protein secretion from M. tuberculosis H37Rv. The samples used in this study were divided into three independent variable groups...

objective(s): this study aimed to develop drugs from natural sources to overcome the side effects of many of synthetic drugs. methanol extracts of both pericarp and seeds of pleiogynium solandri were used to investigate antioxidant, hepatoprotective, and renal function protective, analgesic, and anti-inflammatory effects and to determine the chemical composition of the extract responsible for b...
