The genus Phragmites includes taxa that are very difficult to distinguish macroscopically, and even genetically. To better discriminate these taxa, microscopic traits, such as the epidermis of floral bracts leaves, leaf anatomy, were investigated. In Old World, four distinct giant reeds species (> 3 m) delineated: two tropical species, P. karka mauritianus, Mediterranean altissimus frutescens. ...

Flower structure in grasses is very unique. There are no petals or sepals like in eudicots but instead flowers develop bract-like structures - palea and lemma. Reproductive organs are enclosed by round lodicule that not only protects reproductive organs but also plays an important role during flower opening. The first genetic model for floral organ development was proposed 25 years ago and it w...

Basic questions regarding the origin and evolution of grass (Poaceae) inflorescence morphology remain unresolved, including the developmental genetic basis for evolution of the highly derived outer spikelet organs. To evaluate homologies between the outer sterile organs of grass spikelets and inflorescence structures of nongrass monocot flowers, we describe expression patterns of APETALA1/FRUIT...

Safflower is an important oilseed crop with poorly studied genetic inheritance of the characters. In this study genetically diverse parents were selected which had many contrasting qualitative traits. The used in GMU-1217, GMU- 6854, GMU-6891, GMU-2830, EC 755673 and EC755664. Crosses made between parents. Observations parental traits, traits appearing F1 F2 data analysed for goodness fit by χ2...
