The Arabidopsis TT2 gene encodes an R2R3 MYB domain protein that acts as a key determinant for proanthocyanidin accumulation in developing seed

N Nesi, C Jond, I Debeaujon… - The Plant Cell …, 2001 - mssaleshops.info
In Arabidopsis, proanthocyanidins specifically accumulate in the endothelium during early

Proanthocyanidin composition in the seed coat of lentils (Lens culinaris L.)

M Duenas, B Sun, T Hernández… - … of agricultural and …, 2003 - ACS Publications
Lentils (Lens culinaris L.) are a popular food in many countries. However, little is known
about their phenolic composition. Because polyphenols in lentils are located essentially in
their seed coat, the objective of this work was to study the composition of ...

Purification and characterization of a proanthocyanidin polymer from seed of alfalfa (Medicago sativa cv. beaver)

MR Koupai-Abyazani, J McCallum… - … of agricultural and …, 1993 - ACS Publications
A soluble proanthocyanidin polymer (PAP; condensed tannin) has been histologically
localized in the pallisade layer of the alfalfa seedcoat, purified, and characterized by
spectroscopic, chemical, and biochemical procedures. The polymer consists principally ( ...

… in the common morning glory, Ipomoea purpurea, controls anthocyanin biosynthesis in flowers, proanthocyanidin and phytomelanin pigmentation in seeds, and seed

KI Park, N Ishikawa, Y Morita, JD Choi… - The Plant …, 2007 - Wiley Online Library
The transcriptional regulators for anthocyanin pigmentation include proteins containing
R2R3-MYB domains, bHLH domains and conserved WD40 repeats, and their interactions
determine the set of genes to be expressed. Spontaneous ivory seed (ivs) mutants of ...

The promoter of the Arabidopsis thaliana BAN gene is active in proanthocyanidin-accumulating cells of the Brassica napus seed coat

N Nesi, MO Lucas, B Auger, C Baron, A Lécureuil… - Plant cell reports, 2009 - Springer
Abstract As part of an ongoing research program dedicated to the understanding of
proanthocyanidin (PA) accumulation in Brassica napus seed coat, transgenic rapeseed
plants carrying a 2.3-kb fragment of the Arabidopsis thaliana BAN promoter (ProAtBAN) ...

Effect of early seed removal during fermentation on proanthocyanidin extraction in red wine: A commercial production example

J Lee, JA Kennedy, C Devlin, M Redhead… - Food Chemistry, 2008 - Elsevier
Wines (Vitis vinifera L. cv. Merlot) were made by a commercial winery to examine the effects
of seed removal at∼ 10° Brix on the extraction of proanthocyanidins during fermentation.
Seeds were removed at the point when they fell to the bottom of the fermenter, and were ...

Proanthocyanidin biosynthesis in the seed coat of yellow-seeded, canola quality Brassica napus YN01-429 is constrained at the committed step catalyzed by …

LAL Akhov, PAP Ashe, YTY Tan, RDR Datla… - Botany, 2009 - NRC Research Press
The yellow seed characteristic in Brassica napus L. is desirable because of its association
with higher oil content and better quality of oil-extracted meal. YN01-429 is a yellow-seeded
canola-quality germplasm developed in Canada arising from several years of research. ...
