carbon dioxide is the most important resource for crop growth. in order to investigate the effect of elevated co2 concentration on morphological and physiological characteristics of sesame (sesamum indicum l.) and amaranthus (amaranthus retroflexus l.) an experiment was conducted in greenhouse conditions. the experiment was factorial based on randomized complete block design with six treatments...

Incomplete panicle exsertion in almost all the WA-based CMS lines is one of the major impediments in obtaining higher seed yield in hybrid rice breeding programs. Exploitation of Elongated Uppermost Internode (eui) mutants in rice is a viable genetic strategy to solve this problem. Present study was undertaken with an aim of characterizing the elongated uppermost internode mutants in rice germp...

Carrizo citrange (Citrus sinensisxPoncirus trifoliata) is a citrus hybrid widely used as a rootstock, whose genetic manipulation to improve different growth characteristics is of high agronomic interest. In this work, transgenic Carrizo citrange plants have been produced overexpressing sense and antisense CcGA20ox1 (a key enzyme of GA biosynthesis) under control of the 35S promoter to modify pl...

Setaria viridis is a C4 grass used as a model for bioenergy feedstocks. The elongating internodes in developing S. viridis stems grow from an intercalary meristem at the base, and progress acropetally toward fully expanded cells that store sugar. During stem development and maturation, water flow is a driver of cell expansion and sugar delivery. As aquaporin proteins are implicated in regulatin...

This study describes the successive stages of development of branches from axillary buds in fully rooted plants of Trifolium repens grown in near optimal conditions, and the way in which this developmental pathway differs when nodal root formation is prevented as plants grow out from a rooted base. Cuttings of a single genotype were established in a glasshouse with nodal root systems on the two...

The perennial stoloniferous herbaceous vine Mikania micrantha H.B.K. is among the most noxious exotic invaders in China and the world. Disturbance can fragment stolons of M. micrantha and disperse these fragments over long distances or bury them in soils at different depths. To test their regeneration capacity, single-node stolon fragments with stolon internode lengths of 0, 3, 6 and 12 cm were...

Sorghum is a grain plant that source of food, biofuel and feed, which can be produced using the techniques ratoon cultivation. The objective this study to assess nutrition content, performance four sorghum genotypes vegetative characteristics ratoon. research was carried out from December 2020 July 2021 at Ciawi Research Garden, Livestock Institute. employed treatments (genotype) three replicat...

Phytomyxids are a monophyletic group of biotrophs/parasites variety organisms including seagrasses with wide distribution range that includes the Caribbean. The seagrass Halophila stipulacea, native to Indo-Pacific and Red Sea, is known host for phytomyxids in Mediterranean. However, date phytomyxid infection has not been reported H. stipulacea Infection characterized by swelling leaf petioles ...
