Drivers of strigolactone diversity: P450s in strigolactone biosynthesis

Journal of Integrative Plant Biology, EarlyView.
This review summarizes the discovery and functional identification of cytochrome P450 in strigolactone biosynthesis, classifies and summarizes the members discovered so far, clarifies their biological significance, discusses the technology of strigolactone synthesis research, and finally describes some problems in strigolactone research and potential ...

Spatial analyses of mono, di and trinucleotide trends in plant genes. [PDF]

PLoS ONE, 2011
Genomic DNA sequences display compositional heterogeneity on many scales. In this paper we analyzed tendencies and anomalies in the occurence of mono, di and trinucleotides in structural regions of plant genes.

Cytological characterization and allelism testing of anther developmental mutants identified in a screen of maize male sterile lines. [PDF]

, 2013
Proper regulation of anther differentiation is crucial for producing functional pollen, and defects in or absence of any anther cell type result in male sterility.

Stem microanatomical phenomic uncovers a potential role for ZmLSM2 in regulating maize stem bending strength

Journal of Integrative Plant Biology, EarlyView.
Maize ZmLSM2 (U6 small nuclear ribonucleoprotein specific Sm‐like 2) controls maize stem strength by affecting vascular bundle structure. Using advanced computed tomography imaging and artificial intelligence identified key stem traits linked to lodging resistance and developed a predictive model.

First Nuclear DNA C-values for 18 Eudicot Families [PDF]

Annals of Botany, 2005
A key target set at the second Plant Genome Size Workshop, held at the Royal Botanic Gardens, Kew in 2003, was to produce first DNA C-value data for an additional 1 % of angiosperm species, and, within this, to achieve 75 % familial coverage overall (up from approx. 50 %) by 2009.

Diversity of Pol IV function is defined by mutations at the maize rmr7 locus. [PDF]

PLoS Genetics, 2009
Mutations affecting the heritable maintenance of epigenetic states in maize identify multiple small RNA biogenesis factors including NRPD1, the largest subunit of the presumed maize Pol IV holoenzyme.

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

New Phytologist, EarlyView.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

Phylogenetic relationships among early-diverging eudicots based on four genes: were the eudicots ancestrally woody?

Molecular Phylogenetics and Evolution, 2004
Based on analyses of combined data sets of three genes (18S rDNA, rbcL, and atpB), phylogenetic relationships among the early-diverging eudicot lineages (Ranunculales, Proteales, Trochodendraceae, Sabiaceae, and Buxaceae) remain unclear, as are relationships within Ranunculales, especially the placement of Eupteleaceae.

Modelling stomatal mechanics: a critical review

New Phytologist, EarlyView.
Summary The biomechanics of stomatal movements have fascinated scientists for almost 150 yr, yet we still lack a conclusive and coherent mechanistic understanding of the process. In this review, we present a framework that allows critical insight into the state of knowledge of stomatal biomechanics, with a focus on modelling approaches.

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.
