Examination of the placentae of hot and sweet cultivars of red pepper with light microscopy showed that both types have glandular areas. The placenta of the pungent type has a more conspicuous blister-like surface emerging from the glandular area where the cell wall was detached. The placental surface of the nonpungent type is smooth. In the pungent types, the secreted capsaicinoid droplets produce pressure that detaches part of the cell wall plus the cuticle and leads to the protrusion of the… Expand
Genetic control of pungency in C. chinense via the Pun1 locus.
Results establish that blister formation requires the Pun1 allele and that pun1(2) is a recessive allele from C. chinense that results in non-pungency. Expand
Novel Formation of Ectopic (Nonplacental) Capsaicinoid Secreting Vesicles on Fruit Walls Explains the Morphological Mechanism for Super-hot Chile Peppers
This work compared the morphological structure of fruit pericarp and placental tissue of ''super-hot'' chile peppers to those of jalapeno and bell pepper, leading toceedingly high Scoville heat units for these plants. Expand
Peroxidases and the metabolism of capsaicin in Capsicum annuum L.
Capsaicinoids are acid amides of C9 - C11 branched-chain fatty acids and vanillylamine that are responsible for the pungency of the Capsicum species and of cultivars regarded as hot peppers and cumulative evidence supports that capsaicinoid are oxidized in the pepper by peroxidases. Expand
Capsaicinoids Content in Habanero Pepper (Capsicum chinense Jacq.): Hottest Known Cultivars
The results show considerable intraspecific diversity for this characteristic as well as the existence of cultivars of this species that surpass the levels of pungency reported for Habanero peppers under the conditions evaluated. Expand
Role of peroxidases in capsaicinoids degradation in habanero pepper (Capsicum chinense Jacq.) plants grown under water deficit conditions
PODs activities could not fully explain the formation of the dimer 5,5'-dicapsaicin when these enzymes' activities was immuno-inhibited, suggesting PODs may not be the sole pathway in the degradation process of CAPs in habanero pepper plants under water stress. Expand
Histogenesis of the transmitting tract in Strelitzia reginae
Organisation and development of the stigmatic, stylar and ovarian parts of the transmitting tract in Strelitzia reginae were evaluated and three stages of stigmatic secretion during the development were characterised. Expand
Morpho-structural description of epidermal tissues related to pungency of Capsicum species
Evaluated morphometrics of chili pepper tissues and in the formation of ampullas indicated that DIA morphology characteristics are related to ripening stages, thus indicating commercialisation and processing possibilities. Expand
Selective enzyme-mediated extraction of capsaicinoids and caratenoids from chili guajillo puya (Capsicum annum L.) using ethanol as solvent.
The selective extraction of capsaicinoids and carotenoids from chili guajillo "puya" flour was studied, representing an interesting alternative for the substitution of hexane in industrial processes. Expand
The Pun1 gene for pungency in pepper encodes a putative acyltransferase.
Gen mapping, allele sequence data, expression profile and silencing analysis collectively indicate that the Pun1 locus in pepper encodes a putative acyltransferase, and the pun1 allele, used in pepper breeding for nearly 50 000 years, results from a large deletion at this locus. Expand
Induction of capsaicinoid accumulation in placental tissues of Capsicum chinense Jacq. requires primary ammonia assimilation
Under the conditions tested, the activation of secondary metabolism required activation of basal nitrogen metabolism, suggesting GS participation in fulfilling the demand for amino acids required to support the increase in capsaicinoid synthesis. Expand
