Plant Cell 1994, 6:1877-1887. This paper describes many maize homeobox genes and presents an evolutionary lineage of many plant homeobox genes. Also, a description of mRNA expression of several maize homeodomain proteins suggests that they are expressed in the meristem - the right place to be it they are truly involved in pattern formation in plants.
9. Jackson D, Veit B, Hake S: Expression of maize KNOTTED1-related homeobox genes in the shoot apical meristem predicts patterns of morphogenesis in the vegetative shoot. Development 1994, 120:405-413. In situ expression of several maize knox homeobox mRNAs is reported. Their expression patterns seem to predict morphogenesis from the meristem, suggesting KNOX proteins play an important role in plant morphogenesis. Also, the authors show that kn1 mRNA is expressed only in the meristem corpus, and not in the tunica. Yet, antibodies to KN1 protein detect KN1 in both the tunica and corpus. This correlates with their previous data that an inner cell layer effects the epidermis.

In situ expression of KN1 can be seen at least as early as morphological signs of meristem formation, and probably earlier. This suggests KN1 may be required for meristem formation as well as maintenance.

Lincoln C, Long J, Yamaguchi J, Serikawa K, Hake S: A knotted1-like homeobox gene in Arabidopsis is expressed in the vegetative meristem dramatically alters leaf morphology when overexpressed in transgenic plants. Plant Cell 1994, 6:1859-1876. Like kn1 in maize, expression of KNAT-1 in Arabidopsis is localized to the meristem and down-regulated in the founder cells of the next leaf to be formed. Over-expression of KNAT-1 or KNOTTED-1 in Arabidopsis both cause aberrant leaf development (as in maize). This suggests a conserved function for these proteins over the evolutionary time between monocots and dicots.

17. Becraft PW, Freeling M: Genetic analysis of Rough sheath1 developmental mutants of maize. Genetics 1994, 136:295-311. Several dominant alleles of the homeobox gene rs1 are described. Rs1 mutants are neomorphic and act totally non autonomously to transform the blade to auricle-sheath identity. An enhancer of the mutant allele Rs1-O is described. These studies elucidate a domain in the leaf and have implications for leaf development in general.
18. Fowler, J and Freeling, M: Genetic analysis of mutations that alter cell fates in maize leaves: dominant Liguleless mutations. Dev Genet 1996, in press. Three genes identified by dominant mutations with liguleless phenotypes are mapped and described. Lg3 and probably Lg4 are homeobox genes and act in different domains. To elucidate interactions between knox genes, pairs of double mutants (Lg3-O, Lg4-O and other knox genes) are described and interpreted.
19. Schneeberger RG, Becraft PW, Hake S, Freeling M: Ectopic expression of the knox homeobox gene rough sheath1 alters cell fate in the maize leaf. Genes Dev 1995, 9:2292-2304. Reports that in Rs1-O mutants of maize, ectopic expression of rs1 mRNA occurs in a larger region than the Rs1-O mutant phenotype. This is strong evidence that early acting factors may allow only certain regions of the leaf to be competent to respond to signals that may be expressed ubiquitously. In addition, it supports the suggestion that the maize leaf is composed of domains that demonstrate different competencies. The rs1 sequence is given and compared with that of kn1.

The experiments described by these authors demonstrate that a disk of cells in the meristem, several cell deep and high, is the fundamental unit that gives rise to a single phytomer. In addition, no evidence for strict compartmentalization is found at this earliest stage in leaf primordial development. Localized regions of high mitotic activity are also identified.

Demonstrates that the majority of epidermal sectors generated by reversion of an unstable allele of glossy1 have their borders precisely at veins. This suggests the possibility that one to four cells fated early in development give rise to a developmental module that exists vein-to-vein. Indeed, this work may provide the first clue as to the fundamental mechanism that organizes the lateral dimension. The fact that about half of the sectors are exceptional is not necessarily a problem because so much postprimordial proliferation occurs between the 1 cm primordium and the 1 m leaf.

Boetsch J, Chin J, Croxdale J: Arrest of stomatal initials in Tradescantia is linked to the proximity of neighboring stomata and results in the arrested initials acquiring properties of epidermal cells. Dev Biol 1995, 168:28-38. The spatial arrangement of stomata on mature leaves and the presence of arrested stomatal initials suggest stomata can be controlled, even after initiation. These authors show data that suggest an inhibitory influence is active in promoting stomatal initial arrest if stomata initiate too close to one another.

Dev Biol 1995, 168:39-46. Data in this paper suggest that small groups of epidermal cells become synchronized and determined to give rise to a 'stomatal string', a linear row of cells, containing up to eight stomata. The authors suggest a mechanism other than the usual position-dependent differentiation may be responsible.

Am J Bot 1995, 82:318-327. By cutting individual leaves in half, these authors are able to correlate histology with immunolocalizations of bundle sheath specific or mesophyll-specific enzymes. They clearly demonstrates that differentiation occurs first at the veins, and then proceeds outward to the mesophyll between veins. This helps to order the events in the final differentiation of leaves.

Cells in leaves of the maize tangled mutant are shown to have a very jumbled appearance, unlike the regular long cell files that exist in normal maize. The cells develop this way because of an inability to divide correctly in the longitudinal anticlinal plane. The morphology of the leaf appears normal in all aspects, however, strongly suggesting that cell division pattern plays no role in morphogenesis.
