Isolated polynucleotides and polypeptides and recombinant DNA constructs useful for conferring drought tolerance, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a DTP21 polypeptide.

The present invention relates to a method of evaluating multiple plant individuals or plant lines for deep rooting property under the same culture medium moisture conditions. A method of the present invention is a method of evaluating multiple plant individuals for deep rooting property under the same culture medium moisture conditions, by planting multiple plant individuals together in a sufficiently deep culture vessel and lowering the culture medium moisture content gradually. The present invention also provides a method for evaluating plants for deep rooting property, wherein a culture vessel is installed in a water tank so that the culture medium moisture content can be readily adjusted, and thus management of cultivation conditions is facile and efficient. It is possible to select a plant which can grow in dry and low-groundwater level environment efficiently, by using the method of the present invention. Thus, the method of the present invention can find application in breeding a crop suitable for dry land cultivation and trees usable in desert greening.

Process for producing potato tubers

Method for producing potato microtubers

Method for producing potato tubers using a graft plant

An improved method for producing potato microtubers by tissue culture is provided. The improvement comprises culturing potato plants in a medium containing a high sugar content, i.e., 8% (w/v), for about 1 to 4 weeks under the light prior to culturing the plants in the dark to produce the microtubers.
