Cinnamyl alcohol dehydrogenase (CAD) is an enzyme involved in the synthesis of lignin monomers. Tissue prints were used to localize CAD activity in tomato and poplar tissues. In parallel, lignin deposition was estimated by classical histochemical tests. Image analysis was also used to quantify the amount of CAD activity and the extent of lignification throughout the development of stems. Tomato...

In field trapping tests in Hungary cinnamyl alcohol (3-phenyl-2-propen-l-ol) and transanethole [(1-methoxy-4-(1-propenyl)benzene)] attracted significantly more adult Epicometis (Tropinota) hirta (Coleoptera, Scarabaeidae, Cetoniinae) when presented together in the same bait compared to the single compounds Best attraction was recorded by a 1:1 mixture. Addition of other common floral scent comp...

Wood from biomass plantations with fast growing tree species such as poplars can be used as an alternative feedstock for production of biofuels. To facilitate utilization of lignocellulose for saccharification, transgenic poplars with modified or reduced lignin contents may be useful. However, the potential impact of poplars modified in the lignification pathway on ectomycorrhizal (EM) fungi, w...

چکیده لیگنان¬ها گروه بزرگی از متابولیت¬های ثانوی هستند که در گونه¬های مختلفی از گیاهان حضور دارند. این ترکیبات فعالیت زیستی مختلفی از خود نشان می¬دهند. پودوفیلوتوکسین یک ترکیب لیگنانی است که در گونه¬های گیاهی معدودی حضور دارد و به دلیل خواص ضد سرطانی اهمیت دارویی زیادی دارد. پودوفیلوتوکسین به عنوان پیش¬ماده برای تولید نیمه¬سنتزی داروهای ضد سرطان etoposide teniposide,و etopophosبه کار می¬رود....

Lignin content and composition are two important agronomic traits for the utilization of agricultural residues. Rice (Oryza sativa) gold hull and internode phenotype is a classical morphological marker trait that has long been applied to breeding and genetics study. In this study, we have cloned the GOLD HULL AND INTERNODE2 (GH2) gene in rice using a map-based cloning approach. The result shows...

We describe the three-dimensional structure of sinapyl alcohol dehydrogenase (SAD) from Populus tremuloides (aspen), a member of the NADP(H)-dependent dehydrogenase family that catalyzes the last reductive step in the formation of monolignols. The active site topology revealed by the crystal structure substantiates kinetic results indicating that SAD maintains highest specificity for the substr...
