The DROOPING LEAF (DL) gene has an important function in rice development. Loss-of-function mutation of DL fails to form midrib, a strong structure formed in the central region of the leaf, resulting in a drooping leaf phenotype. In addition, severe mutation in DL causes a floral homeotic change, i.e., replacement of the carpels by the stamens. Thus, DL regulates midrib formation in the leaf an...

Brown midrib mutants have been isolated in maize (Zea mays), sorghum (Sorghum bicolor) and pearl millet (Pennisetum glaucum) arising by either spontaneous or chemical mutagenesis. The characteristic brown coloration of the leaf mid veins is associated with reduced lignin content and altered lignin composition, traits useful to improve forage digestibility for livestock. Brown midrib phenotype i...

BACKGROUND AND AIMS The water-transport capacity of leaf venation is positively related to the leaf-lamina area, because the number and diameter of vein-xylem conduits are controlled to match the lamina area. This study aimed to investigate how this co-ordinated relationship between the leaf-lamina area and vein-xylem characteristics is achieved by examining the midrib xylem of tobacco leaves. ...

Bambusoideae is a diverse subfamily that includes herbaceous (Olyreae) and woody (Arundinarieae and Bambuseae) bamboos. Species within Bambusae are particularly difficult to identify due to their monocarpic lifecycle and the often long durations between mass flowering events; whereas the herbaceous bamboos are pluricarpic, but often are found with no reproductive structures. The leaf blade anat...

Sweet sorghum [Sorghum bicolor (L.) Moench] is characterized by juicy stems with high concentrations of fermentable sugars. The genetic basis of these phenotypes is not understood. A sweet sorghum diversity panel (n = 252), consisting of sweet sorghum cultivars (n = 80) and diverse landraces selected for matching plant height and maturity (n = 172), was genotyped and phenotyped in three environ...

In this research foliar anatomy of seven species of Avena are studied under the light microscope and the scanning electron microscope (SEM). This study includes seven species, namely, A. barbata, A. clauda, A. eriantha, A. fatua, A. ludoviciana, A. sativa and A. wiestii. Different anatomical characters sush as number of bulliform cells, mesophyll thickness, midrib, number of vascular bundles fr...

Leaf morphology is closely related to the growth and development of maize (Zea mays L.) plants and final kernel production. As an important part of the maize leaf, the midrib holds leaf blades in the aerial position for maximum sunlight capture. Leaf midribs of adult plants contain substantial sclerenchyma cells with heavily thickened and lignified secondary walls and have a high amount of phen...

ABSTRACT The growth of good and quality seeds requires a lot fertilization, considering that oil palm grow quickly. Generally, the fertilizers used are compound inorganic single fertilizers. Continuous use without being balanced by organic can reduce soil quality. Therefore, alternative needed to Liquid smoke from midrib-leaf waste be developed into fertilizer, so studies needed. This study aim...
