Animals and plants produce regulatory signals at specific places of their bodies, in order to regulate developmental events which take place at a distance. Plants use this mechanism to adjust their development to the changing environment. Flowering and tuber formation are controlled by signals generated in the leaves that travel throughout the plant to reach their target tissues: the shoot apic...

The genetic control of the switch between seasonal and perpetual flowering has been deciphered in various perennial species. However, little is known about the genetic control of the dynamics of perpetual flowering, which changes abruptly at well-defined time instants during the growing season. Here, we characterize the perpetual flowering pattern and identify new genetic controls of this patte...

Despite advancement in technology and healthcare delivery, infectious diseases still ravage humanity, plants-based remedies remain our major kick back against them. The phytochemical screening, antimicrobial, antioxidant, anti-hyperglycemic activities of n-hexane, ethyl acetate, methanolic extracts Senecio abyssinicus leaves were investigated this study, line with SDG 3, 9 12 goals, following s...

The sponge-dwelling Syllidae Ramisyllis multicaudata and Syllis ramosa are the only annelid species for which a branched body with one head multiple posterior ends is known. In these species, located deep within sponge, branches extend through canal system of their host. morphology creatures has captivated biologists since they were first discovered in late XIXth century, external characteristi...

Launaea sarmentosa (Willd.) Kuntze., an edible perennial herb, is critically considered endangered species due to its habitat destruction. In vitro L. propagation was therefore conducted preserve this plant. Two types of explants including leaf and stolon were applied induce the multiple shoots by culturing on Murashige Skoog (MS) medium supplemented with BA (0, 1, 2 mg/L) 2,4-D 2, 4 mg/L). The...

Abstract The objective of this paper was to review the reproductive biology, herbicide-resistant (HR) biotypes, pollen-mediated gene flow (PMGF), and potential for transfer alleles from HR herbicide-susceptible grass weeds including barnyardgrass, creeping bentgrass, Italian ryegrass, johnsongrass, rigid (annual) wild oats. widespread occurrence is at least partly due PMGF, particularly in obli...

bermudagrass [cynodon dactylon (l.) pers.] is a perennial grass and has been long used as a medicinal herb in iranian traditional medicine to treat varied ailments. different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. g...

Georgia, located in the Southeastern USA, has been historically dominated by two perennial forage grass production systems. Tall fescue (Lolium arundinaceum [Schreb.] S.J. Darbyshire) is more prevalent northern parts of state, while bermudagrass [Cynodon dactylon (L.) Pers.] ubiquitous to southern portion. Climatologists have documented notable changes temperature and precipitation patterns sta...
