A plant material comprises a genomic nucleotide sequence encoding a SUSIBA2 or SUSIBA2-like transcription factor under transcriptional control of a promoter active in the plant material. The genomic nucleotide sequence encoding the SUSIBA2 or SUSIBA2-like transcription factor lacks at least a portion of an activation region of a SUSIBA1 or SUSIBA1-like promote represent in an intron of a wild-type version of the genomic nucleotide sequence encoding the SUSIBA2 or SUSIBA2-like transcription factor. The plant material has a controlled production of carbohydrates, in particular starch or starch and fructan. In particular, the plant material can be designed to produce carbohydrates at enhanced levels.

Lawnmower blade

The invention relates to a lawn mower knife assembly including a rigid bar, plate or disc attached to a motor-driven generally vertical shaft and provided, at a distance from the shaft attachment, with at least two attachment points for knife means, and at least two knife means, each including a blade section provided with a cutting edge and a shank section adapted for the fixation of the knife means to the bar, plate or sheet. The new feature is that each of the attachment points comprises a flat surface section in which there is made a through-hole for a screw or the like and a recess arranged beyond the hole, and that the shank section of each knife means includes a flat surface section with a through-hole and a projection provided adjacent said surface section and extending away from the plane of the surface section, while the surface sections of the attachment points and the shank section are adapted, when in mounted condition, to lie in contact with each other with the holes aligned, and the projection is adapted for accommodation in the recess in order to constitute a rotary latch which is yieldable to pre-determined strain.

The present invention relates to a tightening device for cone belts and the like for use in cone belt transmissions, including at least one preferably driven cone belt pulley which is axially or substantially axially displaceable relative to at least one other, preferably driven cone belt pulley, and a cone belt interconnecting said cone belt pulleys, said tightening device engaging one run of the cone belt by means of a rotary member. The novelty of the invention is that the tightening means includes a preferably spring-loaded support lever arranged adjacent one of the cone belt pulleys and adapted to pivot about a first axis situated substantially parallel with the cone belt pulley shaft and also about an axis oriented generally perpendicular to the first axis, and that a tightening pulley preferably provided with a cone belt groove is fitted at a free end of said support lever in order to maintain the engagement of the tightening pulley independently of any displacement of the cone belt runs caused by the relative displacement of the cone belt pulleys.

Riding lawn mover

The invention relates to a system for motor-driven ride-on lawn mowers of the type where the cutting assembly is placed in front of the front axle, in which the front wheels are adapted as driving and braking wheels and the rear wheels as steering wheels. The new feature is that the brake mechanism acting upon the front wheels is provided with a modulation apparatus which, independently of the power exerted by the driver on the brake pedal or the like, prevents the braking power acting upon the wheels from reaching the amount where the wheels would be locked.
