Abstract: The invention provides non-centrosymmetric organic crystals which show exceptional self-healing properties. More particularly, the present invention provides non-centrosymmetric substituted imidazole and Dialkyl 4,4?-methylenebis(azanediyl)dibenzoate Crystals and a process for preparation thereof. These highly crystalline materials, when broken into pieces, can self-propel and re-join in the blink of an eye and repair themselves so precisely that they become indistinguishable from the undisturbed materials.

Abstract: The present invention relates to a nucleic acid construct. The nucleic acid construct includes a nucleic acid molecule configured to silence or reduce the expression of StBEL11 and/or StBEL29 and variants thereof, a 5? DNA promoter sequence, and a 3? terminator sequence, where the first nucleic acid molecule, the promoter sequence, and the terminator sequence are operatively coupled to permit transcription of the first nucleic acid molecule. The present invention is also directed to vectors, host cells, transgenic plants, and transgenic plant seeds, as well as non-transgenic mutant plants, and methods for altering tuber yield in a plant.
