Unlike many wild grasses, domesticated rice cultivars have uniform culm height and panicle size among tillers and the main shoot, which is an important trait for grain yield. However, the genetic basis of this trait remains unknown. Here, we report that Dwarf Tiller1 (DWT1) controls the developmental uniformity of the main shoot and tillers in rice (Oryza sativa). Most dwt1 mutant plants develo...

Merremia emarginata plants were treated with different plant growth regulators (PGRs): naphthyl acetic acid (NAA), phenyl acetic acid (PAA) and gibberellic acid (GA 3). To determine the role of wall stiffening enzymes in internode elongation, IAA oxidase and peroxidase in the presence of different hydrogen donors like caffeic acid, chlorogenic acid and guaiacol were assayed. The levels of total...

We confirm the hypothesis that Agrobacterium tumefaciens-induced galls produce ethylene that controls vessel differentiation in the host stem of tomato (Lycopersicon esculentum Mill.). Using an ethylene-insensitive mutant, Never ripe (Nr), and its isogenic wild-type parent we show that infection by A. tumefaciens results in high rates of ethylene evolution from the developing crown galls. Ethyl...

Chemical analysis studies were conducted for four populations of switchgrass (Alamo, Kanlow, GA993, and GA992), Panicum virgatum L., which were partitioned into leaves, internodes, and nodes. The variations in carbohydrate compositions, lignin and extractives content, higher heating value (HHV), and the syringyl:guaiacyl ratio of switchgrass were determined. The experimental results indicated t...

Sainfoin (Onobrychis viciifolia Scop.) is a perennial forage crop with desirable properties adapted to temperate climate conditions. The purpose of this research was study the phenotypic correlation coefficients between dry yield and some morphological traits, identify direct indirect effects associated traits. Thus, 32 ecotypes (landraces) were assessed in randomized complete block design layo...

Rice–fish co-cultures have been practiced for over 2000 years, and they tremendous potential in terms of increasing food security economic benefits. However, little research has conducted into achieving stable yields high lodging resistance with regard to rice while simultaneously promoting the harmonious healthy growth fish rice–fish co-culture paddy fields. We a field study aimed at selecting...

1. Plants exhibit adaptations to many stresses, including light competition and herbivory. The expression of these traits may interact negatively, potentially instigating a trade-off. 2. We employed a combination of genetically altered Cucumis sativus varieties and phenotypic manipulations to test for trade-offs in field experiments. The different genetic lines of C. sativus were altered in the...

Sweet, grain, and dual-purpose sorghums differ in a number of important traits, including biomass production, total solutes the stem juice, sugar accumulation across stem. Ten hybrids, two sweet genotypes, grain landraces were characterized under temperate environmental conditions to determine their potential for bioethanol production. Five sorghum hybrids (Ganymed, Hannibal, Tarzan, Merlin, Ze...
