GALS1, GALS2, and GALS3 are members of glycosyltransferase family GT92 in Arabidopsis thaliana. Loss-of-function mutants in the three corresponding genes are deficient in pectic β-1,4-galactan. GALS1 is shown to function as a β-1,4-galactan synthase in vitro, and GALS1 overexpressors have a 50% increased content of β-1,4-galactan in the cell walls.

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.

Coordinated spatiotemporal-specific cell proliferation is critical to plant growth and development. This study demonstrates the function of a mitogen-activated protein kinase cascade downstream of the ERECTA receptor-like kinase in regulating localized cell proliferation, which determines the inflorescence architecture and size in Arabidopsis thaliana.

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.

The Lys catabolite pipecolic acid (Pip) is identified as a critical signal for several forms of inducible plant immunity, acting as a central component of a feedback amplification mechanism that potentiates plant defense responses. Accumulation of Pip is necessary for the establishment of systemic acquired resistance (SAR) and sufficient to trigger SAR-related defense priming.

The Lys catabolite pipecolic acid (Pip) is identified as a critical signal for several forms of inducible plant immunity, acting as a central component of a feedback amplification mechanism that potentiates plant defense responses. Accumulation of Pip is necessary for the establishment of systemic acquired resistance (SAR) and sufficient to trigger SAR-related defense priming.

The fungal pathogen Fusarium graminearum was isolated from inside the host plant (wheat) during three stages of infection using laser microdissection and subjected to microarray analysis. Global expression profiles of in planta–grown and in vitro–grown F. graminearum were compared to elucidate overall infection strategies and the roles that several genes play in pathogenesis were validated.

Photosystem I (PSI) is one of the largest and most complex macromolecular assemblies known in nature. However, the molecular mechanisms of the assembly process of PSI remain largely unknown. This study reports that PSBP-DOMAIN PROTEIN1, a nuclear-encoded chloroplast protein found in the thylakoid lumen, plays an important role in the assembly of the PSI reaction center heterodimer.

Walker, Keiko U. Torii, Shuqun ZhangPlant Cell Dec 2012, 24 (12) 4948-4960; DOI: https://doi.org/10.1105/tpc.112.104695
Coordinated spatiotemporal-specific cell proliferation is critical to plant growth and development. This study demonstrates the function of a mitogen-activated protein kinase cascade downstream of the ERECTA receptor-like kinase in regulating localized cell proliferation, which determines the inflorescence architecture and size in Arabidopsis thaliana.

This article provides an analysis of chloroplast signal recognition particle (cpSRP) evolution within the green and red lineages. A focus lies on the distribution and characterization of the plastid-encoded SRP RNA component. Furthermore, the cpSRP system of Physcomitrella patens containing an SRP RNA and a cpSRP43 component was investigated, and the structure of the cpFtsY receptor was solved.
