Leafbladeless1 mutants are abaxialized, and ectopic outgrowths at abaxial-adaxial boundaries suggest that lamina outgrowth in monocots may be similar to that proposed for dicots [3].

Development. 125:1998;4235-4243. lam1 mutants produce radial leaves lacking adaxial tissues, and it was previously suggested that the loss of polarity in lam1 mutants was post-primordia initiation. On that basis of periclinal chimeras, the authors propose that signals produced in the L3 can restore adaxial tissues in the L2.

EMBO J. 17:1998;170-180. ago1 mutants produce lateral organs that could be interpreted as partially abaxialized. This is supported by gain-of-function alleles in which lateral organs are adaxialized. Although AGO displays sequence similarity to translation initiation factors, the in vivo biochemical function of AGO (and PNH/ZWILLE) is currently unclear.

9. McConnell J.R., Barton M.K. Leaf polarity and meristem formation in Arabidopsis. Development. 125:1998;2935-2942. The semi-dominant phb-1d mutation causes adaxialization of lateral organs with accompanying formation of axillary meristems around the basal circumference of the radial leaves. This and the enlarged apical meristem lead the authors to propose that adaxial leaf fate promotes meristem formation and to suggest that signaling between lateral organs and primordia is required for their proper development, in other words, meristems produce lateral organs, which, in turn, stimulate meristem formation.

The cloning and expression patterns of FIL, YAB2 and YAB3 are presented along with gain-of-function phenotypes of FIL and YAB3. Each of the three gene is expressed abaxially in lateral organs, and FIL and YAB3 can promote abaxial cell fates when ectopically expressed in adaxial positions. FIL is not expressed in adaxialized phb-1d homozygotes. The authors propose that members of the YABBY gene family specify abaxial cell fate in lateral organs.

FILAMENTOUS FLOWER, a meristem and organ identity gene of Arabidopsis, encodes a protein with a zinc finger and HMG-related domains. Genes Dev. 13:1999;1079-1088. The cloning, expression patterns and gain-of-function phenotype of FIL are presented. FIL is expressed abaxially in all lateral organs and can promote abaxial cell fates when ectopically expressed in adaxial positions. The authors propose that FIL promotes abaxial cell fate in lateral organs.

Genetic interactions between crc and gymnos and kanadi are described, as well as the cloning and expression pattern of GYMNOS. The authors propose that both CRC and KANADI promote abaxial cell fate specification, and that GYMNOS negatively regulates genes that promote meristematic potential at the level of chromatin.

Cell. 93:1998;779-789. The cloning and expression pattern of PHAN, a gene previously proposed to promote adaxial fate in lateral organs, is described. Expression is throughout lateral-organ anlagen and primordia, and PHAN is proposed also to promotes proximo-distal development of lateral organs. Conditional alleles indicate that PHAN is required non cell-autonomously for maintenance of a functional meristem, strengthening the argument that signaling between lateral organs and primordia is required for their proper development.
