    Ln Is a Key Regulator of Leaflet Shape and Number of Seeds per Pod in Soybean
    Namhee Jeong, Su Jeoung Suh, Min-Hee Kim, Seukki Lee, Jung-Kyung Moon, Hong Sig Kim, Soon-Chun Jeong
    Plant Cell Dec 2012, 24 (12) 4807-4818; DOI: https://doi.org/10.1105/tpc.112.104968

    Whether the leaflet shape gene Ln has a pleiotropic effect on the number of seeds per pod (NSPP) trait or not has long been debated in soybean research. This study shows that both the leaflet shape and NSPP traits are regulated by a single gene, which is a homolog of Arabidopsis JAGGED that regulates leaf and flower development, and establishes a novel role for JAGGED in fruit development.

    Soluble Carbohydrates Regulate Auxin Biosynthesis via PIF Proteins in Arabidopsis
    Ilkka Sairanen, Ondřej Novák, Aleš Pěnčík, Yoshihisa Ikeda, Brian Jones, Göran Sandberg, Karin Ljung
    Plant Cell Dec 2012, 24 (12) 4907-4916; DOI: https://doi.org/10.1105/tpc.112.104794

    Plants adjust growth to suit opportunities and limitations in their environment. Sugars from photosynthesis, the hormone auxin, and members of the PHYTOCHROME INTERACTING FACTOR (PIF) family of proteins have all been shown individually to regulate growth. This work shows that sugars regulate auxin biosynthesis via PIF proteins, indicating that the three in fact act together in growth regulation.
