Turmeric (Curcuma longa L. (Zingiberaceae)) is a rich source of medicinally important chemical compounds obtained from both pseudostem (aboveground part) and rhizome (underground part). However, the availability disease-free elite varieties plant highly restricted. Leaf spot caused by Colletotrichum curcumae Butler & Bisby bacterial wilt Ralstonia pseudosolanacearum Safni have been reported as ...

Although the number and form of metazoan organs are determined in the embryo, plants continuously form organs via pluripotent stem cells contained within the meristem. Flowering plants have an indeterminate meristem in their diploid generation, whereas the common ancestor of land plants is inferred to have formed an indeterminate meristem in its haploid generation, as observed in the extant bas...

Maturation in conifers includes several distinct and persistent changes in the growth habits of apical meristems. Despite many studies on maturation in conifers, there are still many aspects of the process that have not been elucidated. For example, it is not known why maturation of cotyledon-derived tissue culture plantlets is rapid, whereas the natural maturation process is gradual. Also, it ...

Imagine a textbook entitled Developmental Biology that focuses entirely on plants, mentioning animals only for their peculiar way of making germ cells by setting aside a group of precursor cells early in the embryo. The converse has been, and still is, common practice. It is true that the regenerative potential of plants, which is indeed impressive, sets them apart from the more familiar animal...
