طی سی سال گذشته کلزا به یکی از محصولات عمده کشاورزی تبدیل شده است و در حال حاضر نیز سومین منبع روغن گیاهی پس از سویا و نخل روغنی می باشد. بذور آن علاوه بر سطح بالای لیپید، حاوی پروتئین قابل توجهی هستند که حدوداً 25-20 درصد از وزن خشک بذر را تشکیل می دهد. یکی از پروتئین های ذخیره ای مهم در جنین های کلزا پروتئین ناپین (napin) است که طی توسعه بذر ساخته می شود. سنتز پروتئین-های ذخیره ای در ابتدا در ...
Phytoene synthase (PSY) has been shown to catalyze the first committed and rate-limiting step of carotenogenesis in several crop species, including Brassica napus L. Due to its pivotal role, PSY has been a prime target for breeding and metabolic engineering the carotenoid content of seeds, tubers, fruits and flowers. In Arabidopsis thaliana, PSY is encoded by a single copy gene but small PSY ge...
Over the last fifteen years, considerable progress has been made in the field of “green chemistry”, as regards both research aspects and market development. In particular, extraction of erucic acid (C22:1) from plants and its industrial applications have received increasing attention. At present, known species producing oils yielding large quantities of erucic acid belong, with few exceptions, ...
BACKGROUND Fatty acids synthesized in chloroplast are transported to endoplasmic reticulum (ER) for triacylglycerols (TAGs) resembling. The development of chloroplast also requires lipids trafficking from ER to chloroplast. The membrane contact sites (MCSs) between ER and chloroplast has been demonstrated to be involved for the trafficking of lipids and proteins. Lipids trafficking between ER a...
Oilseed rape (Brassica napus L.) was formed ~7500 years ago by hybridization between B. rapa and B. oleracea, followed by chromosome doubling, a process known as allopolyploidy. Together with more ancient polyploidizations, this conferred an aggregate 72× genome multiplication since the origin of angiosperms and high gene content. We examined the B. napus genome and the consequences of its rece...
A novel subclass of dehydrin genes, homologous to the Raphanus sativus late embryogenesis-abundant (LEA) protein (RsLEA2) and the Arabidopsis thaliana dehydrin, was isolated from Brassica juncea and Brassica napus, here designated BjDHN1 and BnDHN1, respectively. The cDNA of BjDHN1 and BnDHN1 genes share 100% nucleotide identity. The encoded protein is predicted to consist of 183 amino acid res...
The effect of the number of pods on the main inflorescence (NPMI) on seed yield in Brassica napus plants grown at high density is a topic of great economic and scientific interest. Here, we sought to identify patterns of gene expression that determine the NPMI during inflorescence differentiation. We monitored gene expression profiles in the main inflorescence of two B. napus F6 RIL pools, each...
developing seeds of oilseed rape is fundamental to the rational development of biotechnological strategies for The effect of sucrose concentration on triacylglycerol increasing seed oil content and manipulating oil composibiosynthesis and associated gene expression was tion. In oilseeds, the biosynthesis of TAG in developing examined in a microspore-derived cell suspension culseeds is catalysed...
This study was conducted at the Agricultural Research Station, Hada El-Sham, King Abdulaziz University during 2006 and 2007 seasons. Four canola varieties, Callypso, Pactole, Sero-4 and Sero-6 varieties were tested under four nitrogen fertilizer rates (0.00, 92,138 and 184 kg N/ha) to determine the effect of nitrogen fertilizer on the canola (Brassica napus L.) seed yield, yield components and ...
Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...
