Annotation: Study reports genetic and cell biological analyses of the zygote-arrest 1 (zyg1) mutant in Arabidopsis, which showed zygote-lethal and over-accumulation of cyclin B1 D-box-GUS in ovules. These results together suggest that APC/C-mediated degradation of cyclin B1 in Arabidopsis is critical for initiating the first division of the zygote.

Annotation: Genes controlling SCW formation were activated by the overexpression of LBD30, but not in the LBD30(K226R) mutant. LBD30 enhancement of SCW formation resulted from upregulation of SND1/NST1-mediated transcriptional networks. This study presents a mechanism by which sumoylation of LBD30, mediated by SIZ1, regulates SCW formation in A. thaliana.

Annotation: Study shows that ARF DNA-binding domains ahomodimerize to generate cooperative DNA binding, which is critical for in vivo ARF5/MP function. Strikingly, DNA-contacting residues are conserved between ARFs, and found that monomers have the same intrinsic specificity; ARF1 and ARF5 homodimers, however, differ in spacing tolerated between binding sites.

Annotation: Study identified ORG3 as a direct downstream, and positively regulated target of GRF9. Genetic analysis of grf9 org3 and GRF9ox org3 double mutants reveals that both transcription factors act in a regulatory cascade to control the final leaf dimensions by restricting cell number in the developing leaf in Arabidopsis thaliana.

Annotation: This study has shown that mMDH is an important respiratory element in Arabidopsis seeds, with a significant impact on early seedling growth. Perturbation of both mMDH genes in Arabidopsis seeds significantly elevated respiration rates at all stages of seed maturation, markedly reduced reserve accumulation, and accelerated the aging process in seeds.

Annotation: Study shows that the integration of PDX1.2 into a heteromeric dodecamer assembly with PDX1.3 does not cause a major structural deviation from the overall architecture of the homomeric complex. Nonetheless, the structure of the PDX1.2-PDX1.3 complex highlights enhanced flexibility in key catalytic regions for the initial steps of vitamin B6 biosynthesis.

Annotation: Study revealed that in Arabidopsis sucrose transporter SUC2 activity is regulated via its protein turnover rate and phosphorylation state. UBIQUITIN-CONJUGATING ENZYME 34 (UBC34) was found to trigger turnover of SUC2 in a light-dependent manner.

Annotation: Study demonstrates that the nuclear and Golgi-localized protein BLISTER (BLI) negatively controls the activity of IRE1A/IRE1B under normal growth condition in Arabidopsis. Its loss-of-function mutation results in chronic up-regulation of a set of both canonical unfolded protein response (UPR) genes and non-canonical UPR downstream genes, leading to cell death and growth retardation.

Annotation: Study shows that in Arabidopsis non-CG methylation in CTCTGYTY motifs is one way to prevent REF6 targeting. Structural analysis demonstrates that CHG methylation is unfavorable for REF6 binding and attenuates REF6-binding affinity. Results reveal a mechanism for a transcriptional-activating histone-modifying enzyme in avoiding heterochromatic binding through its intrinsic DNA methylation unfavorable DNA-binding activity.

Annotation: Study discovered SOBIR1/EVR as a regulator of secondary growth. SOBIR1/EVR acts through a mechanism that involves BREVIPEDICELLUS (BP) and ERECTA (ER), two proteins previously known to regulate xylem fiber development. BP binds SOBIR1/EVR promoter and that SOBIR1/EVR expression is enhanced in bp mutants, suggesting a direct, negative regulation of BP over SOBIR1/EVR expression.
