Gore, Dean DellaPennaPlant Cell Dec 2013, 25 (12) 4827-4843; DOI: https://doi.org/10.1105/tpc.113.119370
Genome-wide association studies of free branched-chain amino acids (BCAAs) in Arabidopsis seeds identified BRANCHED-CHAIN AMINO ACID TRANSFERASE2 (BCAT2), one of seven BCATs encoded in the genome, as an important regulator of BCAA natural variation. The mitochondrial localization of BCAT2 is consistent with a catabolic function and highlights the importance of catabolism in determining seed BCAA levels.

Gore, Dean DellaPennaPlant Cell Dec 2013, 25 (12) 4812-4826; DOI: https://doi.org/10.1105/tpc.113.119677
Analysis of natural variation in Arabidopsis identified CAROTENOID CLEAVAGE DIOXYGENASE4 (CCD4) as a major negative regulator of β-carotene content in seeds and senescing leaves. Given that global vitamin A deficiency is due in part to low β-carotene levels in seeds of major food crops, this study suggests that CCDs may be critical targets for enhancing the provitamin A carotenoid levels of food crops.

Sterol biosynthetic intermediates (SBIs) derived from the sterol C4-demethylation complex tethered by ERG28 represent signaling molecules in mammals and fungi. In Arabidopsis, loss of ERG28 function leads to the accumulation of the previously undetected SBI, 4-carboxy-4-methyl-24-methylenecycloartanol, which inhibits polar auxin transport. Our work provides a link between sterol metabolism and auxin transport.

Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

This article elucidates molecular details of meiotic DNA repair by analyzing the interhomolog-promoting factor HOP2. The study found that the recombinase DMC1 requires high levels of HOP2 for repair via the homologous chromosome but only minimal amounts to allow the recombinase RAD51 to perform intersister DNA repair, indicating that DMC1 exerts a negative regulatory effect on RAD51, which is alleviated by HOP2.

Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

Sterol biosynthetic intermediates (SBIs) derived from the sterol C4-demethylation complex tethered by ERG28 represent signaling molecules in mammals and fungi. In Arabidopsis, loss of ERG28 function leads to the accumulation of the previously undetected SBI, 4-carboxy-4-methyl-24-methylenecycloartanol, which inhibits polar auxin transport. Our work provides a link between sterol metabolism and auxin transport.

This article elucidates molecular details of meiotic DNA repair by analyzing the interhomolog-promoting factor HOP2. The study found that the recombinase DMC1 requires high levels of HOP2 for repair via the homologous chromosome but only minimal amounts to allow the recombinase RAD51 to perform intersister DNA repair, indicating that DMC1 exerts a negative regulatory effect on RAD51, which is alleviated by HOP2.

Sterol biosynthetic intermediates (SBIs) derived from the sterol C4-demethylation complex tethered by ERG28 represent signaling molecules in mammals and fungi. In Arabidopsis, loss of ERG28 function leads to the accumulation of the previously undetected SBI, 4-carboxy-4-methyl-24-methylenecycloartanol, which inhibits polar auxin transport. Our work provides a link between sterol metabolism and auxin transport.

Both in vitro and in vivo biochemical and genetic evidence demonstrated that a group of Kelch repeat F-box proteins physically interact with PAL isozymes, mediating their degradation via the ubiquitination-26S proteasome system, thus affecting phenylpropanoid biosynthesis.

Analysis of natural variation in Arabidopsis identified CAROTENOID CLEAVAGE DIOXYGENASE4 (CCD4) as a major negative regulator of β-carotene content in seeds and senescing leaves. Given that global vitamin A deficiency is due in part to low β-carotene levels in seeds of major food crops, this study suggests that CCDs may be critical targets for enhancing the provitamin A carotenoid levels of food crops.

- Open AccessThe Trans-Acting Short Interfering RNA3 Pathway and NO APICAL MERISTEM Antagonistically Regulate Leaf Margin Development and Lateral Organ Separation, as Revealed by Analysis of an argonaute7/lobed leaflet1 Mutant in Medicago truncatulaChuanen Zhou, Lu Han, Chunxiang Fu, Jiangqi Wen, Xiaofei Cheng, Jin Nakashima, Junying Ma, Yuhong Tang, Yang Tan, Million Tadege, Kirankumar S. Mysore, Guangmin Xia, Zeng-Yu WangPlant Cell Dec 2013, 25 (12) 4845-4862; DOI: https://doi.org/10.1105/tpc.113.117788
This work shows that a mutation of the ARGONAUTE7 ortholog (LOBED LEAFLET1) in Medicago truncatula causes lobed leaf margins and more widely spaced lateral organs. Characterization of the mutant revealed a balanced developmental mechanism involving several regulators that determine the final shape of leaf margin and the separation of lateral organs.

- Open AccessCalcium/Calmodulin-Dependent Protein Kinase Is Negatively and Positively Regulated by Calcium, Providing a Mechanism for Decoding Calcium Responses during Symbiosis SignalingJ. Benjamin Miller, Amitesh Pratap, Akira Miyahara, Liang Zhou, Stephen Bornemann, Richard J. Morris, Giles E.D. OldroydPlant Cell Dec 2013, 25 (12) 5053-5066; DOI: https://doi.org/10.1105/tpc.113.116921
This study dissects the regulation of a calcium/calmodulin-dependent protein kinase (CCaMK) during symbiotic signaling and reveals that CCaMK is both negatively and positively regulated by calcium to create a robust molecular switch that is responsive to calcium concentrations associated with both the basal state and with oscillations.

AssmannPlant Cell Dec 2013, 25 (12) 4789-4811; DOI: https://doi.org/10.1105/tpc.113.119800
The authors performed metabolomics analysis on a time series of guard cell samples treated with abscisic acid (ABA) to follow the dynamics of 85 metabolites potentially involved in ABA signaling. ABA rapidly altered the profiles of numerous metabolites, including other hormones and calcium-mobilizing agents. ABA responses were greater in the wild type than in a G-protein mutant with ABA-hyposensitive stomata.
