Root development

Effect of soil moisture stress on root and shoot development of seven wheat (triticum aestivum L.) cultivars

ارزیابی نقش ویژگی‌های ریخت‌شناسی ریشه گیاه تریتیکاله (Triticale spp) در تولید دانه تحت شرایط کمبود آب

Plant roots, with respect to their intrinsic characteristics, have important role in both improvement and development of germplasms of drought resistant plants. This experiment was conducted to study direct and indirect effects of root morphological traits on grain yield of four triticale genotypes (three promising lines of ET-82-8, ET-82-15 and ET-79-17 along with the conventional Junillo-92...

Effect of Hydrogen Peroxide, Ascorbic Acid and Indolic-3-Butyric Acid on Root Induction and Development in Cuttings of Bougainvillea spectabilis

Bougainvillea (Bougainvilleaspectabilis) is used for planting in the landscape because of their beautiful and colorful flowers. The easiest and cheapest technique to propagate this plant is by cuttings; however the cuttings of this plant are not easily rooted and require the special treatments, including the use of auxin. For this purpose, an experiment was performed in Completely Rand...

ROOT HAIR DEFECTIVE SIX-LIKE Class I Genes Promote Root Hair Development in the Grass Brachypodium distachyon

Genes encoding ROOT HAIR DEFECTIVE SIX-LIKE (RSL) class I basic helix loop helix proteins are expressed in future root hair cells of the Arabidopsis thaliana root meristem where they positively regulate root hair cell development. Here we show that there are three RSL class I protein coding genes in the Brachypodium distachyon genome, BdRSL1, BdRSL2 and BdRSL3, and each is expressed in developi...

Root development in Arabidopsis: four mutants with dramatically altered root morphogenesis.

A genetic analysis of root development in Arabidopsis thaliana has identified mutants that have abnormal morphogenesis. Four of these root morphogenesis mutants show dramatic alterations in post-embryonic root development. The short-root mutation results in a change from indeterminate to determinate root growth and the loss of internal root cell layers. The cobra and lion's tail mutations cause...

MADS-Box Transcription Factor AGL21 Regulates Lateral Root Development and Responds to Multiple External and Physiological Signals

Plant root system morphology is dramatically influenced by various environmental cues. The adaptation of root system architecture to environmental constraints, which mostly depends on the formation and growth of lateral roots, is an important agronomic trait. Lateral root development is regulated by the external signals coordinating closely with intrinsic signaling pathways. MADS-box transcript...
