DEVELOPMENTAL BIOLOGY, 7, 432-444 ( 1963) Development in Organ Tissue Culture of Kidney Rudiments from Mutant Mouse Embryos3'2 SALOME GLUECKSOHN-WAELSCH AND TERESA RONDON ROTA3 Department of Anatomy, Albert Einstein College of Medicine, New York, New York Accepted October 31, 1962 INTRODUCTION A number of years ago we described a mutation in the house mouse causing absence or reduction in size Can we suppose that the formation of rudimentary teeth which are subsequently absorbed, can be of any service to the rapidly growing embryonic calf by the excretion of precious phosphate of lime?" Note: “these rudimentary or atrophied organs, are imperfect and useless”. Despite the divergence between OsCUC1 and CUC1/2, the mechanisms of meristem/organ boundary specification are conserved between the dicot Arabidopsis and the monocot O. sativa (Fig. 8): one or more microRNA (osa‐miR164/miR164) target(s) (OsCUC1/CUC1&CUC2) function redundantly with another NAC gene family member (OsCUC3/CUC3) in meristem/organ boundary specification. 2020-01-02 · Some organs are referred to as “vestigial” because they are assumed to be a “vestige”—a leftover—from an earlier evolutionary form. The term vestigial implies a lack of use, purpose, or function.

In the last 150 years, in numerous creatures, organs have been discovered which were initially categorised as rudimentary, incomplete and useless. However, most often it was subsequently demonstrated that they were of great real benefit to the overall organism. In other cases it was down to atrophy.

Although AMs have important functions in plant development, our knowledge of organ boundary and AM formation remains rudimentary. Here, we generated a cellular-resolution genomewide gene expression map for low-abundance Arabidopsis thaliana organ boundary cells and constructed a genomewide protein-DNA interaction map focusing on genes affecting boundary and AM formation.

Such is not the case, however, in the higher vertebrates that possess eggs with enormous amounts of yolk, as do the Gastrula, early multicellular embryo, composed of two or more germinal layers of cells from which the various organs later derive. The gastrula develops from the hollow, single-layered ball of cells called a blastula which itself is the product of the repeated cell division, or cleavage, of a 2020-05-15 · In the lf1 mutant, one or two lateral florets were formed in the axilla of the sterile lemmas, while in the fon4 mutant, some spikelets formed extra lemma-like organs while other spikelets developed two lemma-like and palea-like organs and four lodicules, suggesting the formation of two florets. During puberty, tubule formation is coupled with branching morphogenesis which establishes the basic arboreal network of ducts emanating from the nipple.
