The Immense Diversity of Floral Monosymmetry and Asymmetry Across Angiosperms [PDF]

open access: yes, 2018
Floral monosymmetry and asymmetry are traced through the angiosperm orders and families. Both are diverse and widespread in angiosperms. The systematic distribution of the different forms of monosymmetry and asymmetry indicates that both evolved numerous

A simplified explanation for the frameshift mutation that created a novel C-terminal motif in the gene lineage [PDF]

open access: yes, 2006
Background The evolution of type II MADS box genes has been extensively studied in angiosperms. One of the best-understood subfamilies is that of the Arabidopsis gene APETALA3 (AP3).

The Leaf Length-Width Method Is Applicable to Compound Leaves of Diverse Forms

open access: yesAgriculture
To estimate leaf area, the length-width method, also called the Montgomery equation, has been widely used. It is an empirical formula stating that within a given species, the area of a leaf is proportional to the product of its length and width. Although

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

open access: yes, 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.
