Sulfonylurea-resistant mutants of Arabidopsis thaliana
TLDR
Acetohydroxy acid synthase activity in extracts from chlorsulfuron-resistant plants was much less-susceptible to inhibition by chloursulfuron and a structurally related inhibitor than the activity in wild-type extracts, which suggests that the csr locus is the structural gene for acetohydroxy Acid synthase.
Differentiation of mucilage secretory cells of the Arabidopsis seed coat.
TLDR
This work has used microscopy to investigate the structure and differentiation of Arabidopsis seed coat mucilage cells, including cell morphogenesis and the synthesis, secretion, and extrusion of mucilage.
The UNUSUAL FLORAL ORGANS gene of Arabidopsis thaliana is an F-box protein required for normal patterning and growth in the floral meristem.
TLDR
It is shown here that UFO is an F-box protein that interacts with Arabidopsis SKP1-like proteins, both in the yeast two-hybrid system and in vitro, which is likely to target for degradation specific proteins controlling normal growth patterns in the floral primordia.
BLADE-ON-PETIOLE–Dependent Signaling Controls Leaf and Floral Patterning in Arabidopsis
TLDR
It is shown that two NPR1-like genes, BLADE-ON-PETIOLE1 (BOP1) and BOP2, function redundantly to control growth asymmetry, an important aspect of patterning in leaves and flowers.
LEAFY, a Homeotic Gene That Regulates Inflorescence Development in Arabidopsis.
TLDR
Results from double mutant analysis, showing that lfy-1 is epistatic to the floral organ homeotic gene ap2-6, are consistent with the hypothesis that a functional LFY gene is necessary for the expression of downstream genes controlling floral organ identity.
Genetic analysis of seed coat development in Arabidopsis.
A large family of bacterial activator proteins.
TLDR
The combined evidence indicates that all nine proteins in the LysR family are related by common ancestry, are similarly folded, and are not detectably related to other known bacterial regulatory proteins.
A Novel Fatty Acyl-CoA Synthetase Is Required for Pollen Development and Sporopollenin Biosynthesis in Arabidopsis[C][W]
TLDR
It is proposed that ACOS5 encodes an enzyme that participates in a conserved and ancient biochemical pathway required for sporopollenin monomer biosynthesis that may also include the Arabidopsis CYP703A2 and MS2 enzymes.
Genetic analysis of the floral initiation process (FLIP) in Arabidopsis
TLDR
Besides their role in establishing the floral program, phenotypes of flower-like lateral shoots in mutant inflorescences suggest that all three, LEAFY, APETALA1 and APETalA2, influence expression of whorl identity genes.
Isolation and characterization of mutants defective in seed coat mucilage secretory cell development in Arabidopsis.
TLDR
The results show that the genes identified define several events in seed coat differentiation, and although APETALA2 is needed for differentiation of both outer layers of the seed coat, TRANSPARENT TESTAGLABRA1, GLABRA2, and MUM4 are required for complete mucilage synthesis and cytoplasmic rearrangement.
