TL;DR: Basal leaf segments of 3 to 4 week old maize seedlings plated on SH medium with 30 μM dicamba produced embryogenic callus and/or somatic embryos that germinated and the resulting seedlings could be established in culture tubes.
Abstract: Basal leaf segments of 3 to 4 week old maize (Zea mays L.) seedlings plated on SH medium with 30 μM dicamba produced embryogenic callus and/or somatic embryos. Histological evidence showed that some of the embryos arose directly from the explant. When leaf segments with embryos were transferred to MS medium with 1.0 μM NAA, 1.0 μM IAA, 2.0 μM 2iP, and 60 g/l sucrose, the embryos germinated and the resulting seedlings could be established in culture tubes. These responses were obtained from three inbred lines, CHI31, S615, and S7.

TL;DR: In this article, the authors provided an inbred corn plant designated 89AHD12, which was used to produce corn seeds and plants produced by crossing the inbred plant with another corn plant, such as another inbred, and to crosses with related species.
Abstract: According to the invention, there is provided an inbred corn plant designated 89AHD12. This invention thus relates to the plants, seeds and tissue cultures of the inbred corn plant 89AHD12, and to methods for producing a corn plant produced by crossing the inbred corn plant 89AHD12 with itself or with another corn plant, such as another inbred. This invention further relates to corn seeds and plants produced by crossing the inbred plant 89AHD12 with another corn plant, such as another inbred, and to crosses with related species. This invention further relates to the inbred and hybrid genetic complements of the inbred corn plant 89AHD12, and also to the SSR and genetic isozyme typing profiles of inbred corn plant 89AHD12.

TL;DR: An inbred corn line, designated LH283BtMON810, is disclosed in this paper, which relates to the seeds of the inbred line and to the plants of the line.
Abstract: An inbred corn line, designated LH283BtMON810, is disclosed. The invention relates to the seeds of inbred corn line LH283BtMON810, to the plants of inbred corn line LH283BtMON810 and to methods for producing a corn plant, either inbred or hybrid, by crossing the inbred line LH283BtMON810 with itself or another corn line. The invention further relates to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other inbred corn lines derived from the inbred LH283BtMON810.

TL;DR: A transformation approach involving overexpression of the maize (Zea mays) Baby boom (Bbm) and maize Wuschel2 (Wus2) genes, which produced high transformation frequencies in numerous previously nontransformable maize inbred lines is reported.
Abstract: While transformation of the major monocot crops is currently possible, the process typically remains confined to one or two genotypes per species, often with poor agronomics, and efficiencies that place these methods beyond the reach of most academic laboratories. Here, we report a transformation approach involving overexpression of the maize (Zea mays) Baby boom (Bbm) and maize Wuschel2 (Wus2) genes, which produced high transformation frequencies in numerous previously nontransformable maize inbred lines. For example, the Pioneer inbred PHH5G is recalcitrant to biolistic and Agrobacterium tumefaciens transformation. However, when Bbm and Wus2 were expressed, transgenic calli were recovered from over 40% of the starting explants, with most producing healthy, fertile plants. Another limitation for many monocots is the intensive labor and greenhouse space required to supply immature embryos for transformation. This problem could be alleviated using alternative target tissues that could be supplied consistently with automated preparation. As a major step toward this objective, we transformed Bbm and Wus2 directly into either embryo slices from mature seed or leaf segments from seedlings in a variety of Pioneer inbred lines, routinely recovering healthy, fertile T0 plants. Finally, we demonstrated that the maize Bbm and Wus2 genes stimulate transformation in sorghum (Sorghum bicolor) immature embryos, sugarcane (Saccharum officinarum) callus, and indica rice (Oryza sativa ssp indica) callus.
