Monocots

Monocots are flowering plants whose embryos produce a single seed leaf, or cotyledon, making them a major lineage within angiosperm biology. During development, this embryonic pattern is associated with characteristic traits such as parallel leaf veins, fibrous root systems, scattered vascular bundles in stems, and flower parts commonly arranged in threes. Monocots include grasses, cereals, palms, lilies, and orchids, linking the concept to plant structure, evolution, and classification. Their study supports crop improvement and ecological research, while their distinctive anatomy helps researchers identify species, interpret evolutionary relationships, and understand adaptations to diverse environments.

Seed Structure and Early Development of the Sporophyte

0 Views •

2020

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo. The embryo contains a double set of chromosomes, one set from each parent. Fertilization of the haploid egg by the haploid sperm gives rise to the zygote, which develops into the embryo. The endosperm is a...

2016

Quantifying cell division and expansion is of crucial importance to the understanding of whole-plant growth. Here, we present a protocol to calculate cellular parameters determining maize leaf growth rates and highlight the use of these data for investigating molecular growth regulatory mechanisms by directing developmental stage-specific sampling strategies.

Here, we present an interactome capture protocol applied to Arabidopsis thaliana leaf mesophyll protoplasts. This method critically relies on in vivo UV crosslinking and allows for the isolation and identification of plant mRNA-binding proteins from a physiological environment.

Lignin Down-regulation of Zea mays via dsRNAi and Klason Lignin Analysis

2014

A double stranded RNA interference (dsRNAi) technique is employed to down-regulate the maize cinnamoyl coenzyme A reductase (ZmCCR1) gene to lower plant lignin content. Lignin down-regulation from the cell wall is visualized by microscopic analyses and quantified by the Klason method. Compositional changes in hemicellulose and crystalline cellulose are analyzed.
