The Cellulose Synthase-Like D (CslD) genes have important, although still poorly defined, roles in cell wall formation. Here, we show an unexpected involvement of CslD1 from maize (Zea mays) in cell division. Both division and expansion were altered in the narrow-organ and warty phenotypes of the csld1 mutants. Leaf width was reduced by 35%, due mainly to a 47% drop in the number of cell files ...

bambara groundnut [vigna subterranea (l.) verdc.] is an indigenous legume crop in africa. it has comparable value to other legumes for food and nutritional security in the continent. however, small-scale farmers continue cultivating unimproved landrace varieties over the production areas in sub-saharan africa. bambara groundnut landraces exist as heterogeneous mixtures of seeds, which typically...

Recognizing plants is a vital problem especially for biologists, chemists, and environmentalists. Plant recognition can be performed by human experts manually but it is a time consuming and low-efficiency process. Automation of plant recognition is an important process for the fields working with plants. This paper presents an approach for plant recognition using leaf images. Shape and color fe...

The present study was conducted to investigate the Bergenia ciliata (Haw.) Sternb. (Family: Saxifragaceae) for pharmacognostic study including macroscopical and microscopical observations, leaf surface features, Scanning Electron Microscopy and Fluorescence characters. The macroscopy revealed that rhizome was brown in color, hard in fracture, pleasant in odor and astringent in taste. Leaf was c...

We evaluated factors influencing the development of autumn red coloration in leaves of sugar maple (Acer saccharum Marsh.) by measuring mineral nutrient and carbohydrate concentrations, water content, and phenology of color development of leaves from 16 mature open-grown trees on 12 dates from June through October 1999. Mean foliar nutrient and carbohydrate concentrations and water content were...

WequantiÞed thedensity-dependent effects of herbivory by thepsyllidBoreioglycaspis melaleucae Moore on the senescence of expanding and fully expanded leaves from two chemical variants (chemotypes) of the invasive tree Melaleuca quinquenervia (Cav.) S. T. Blake. Foliar chlorophyll content (OD) and percent nitrogen were not inßuenced by leaf age classes and chemotypes. In contrast, increases in t...

in order to evaluate the effects of planting pattern on morphological, phonological, yield and yield components of sweet and super sweet corn (zea mays l.) varieties under saline conditions, a field experiment was conducted as split plots based on a randomized complete block design with four replications. planting pattern in 3 levels included one row in ridge, two row in ridge and furrow planti...

mulches bring several benefits to lettuce cultivation.a study on the lettuce ‘red rapids’ has been conducted to determine the influence of the different colored plastic mulch on its growth. the experiment consisted of five color treatments as follows; treatment 1- metallic silver (control), treatment 2- red, treatment 3- orange, treatment 4- yellow and treatment 5-green. results showed that the...
