Correlations between developmentally plastic traits may constrain the joint evolution of traits. In plants, both seedling de-etiolation and shade avoidance elongation responses to crowding and foliage shade are mediated by partially overlapping developmental pathways, suggesting the possibility of pleiotropic constraints. To test for such constraints, we exposed inbred lines of Impatiens capens...

the sharp upper bounds and the sharp lower bounds of the largest eigenvalues $lambda_1$, the least eigenvalue $lambda_n$, the second largest eigenvalue $lambda_2$, the spread and the separator among all firefly graphs on $n$ vertices are determined.

St. Augustinegrass is a widely used turf and pasture grass in the southern US. Raleigh is a cultivar known for superior cold tolerance than other St. Augustinegrass cultivars. However, its coarse-leaf texture and long internodes are undesirable when planted in home lawns. Mutagenesis by gamma ray irradiation was employed to treat node cuttings and calli for inducing semi-dwarf growth phenotype....

Each student should select a paper to present to the class and notify Professor Warnow of this selection by e-mail prior to next Tuesday's lecture. Scribe Notes. Beginning with today's lecture, a designated scribe will be responsible for taking notes on each lecture, typesetting a polished and thorough version of the notes in L A T E X, e-mailing the notes in both .tex and .pdf formats to Profe...

There is increasing interest in evaluating the environmental effects on crop architectural traits and yield improvement. However, crop models describing the dynamic changes in canopy structure with environmental conditions and the complex interactions between canopy structure, light interception, and dry mass production are only gradually emerging. Using tomato (Solanum lycopersicum L.) as a mo...

In the present study, we have employed the ligand-based drug design technique, 3D-QSAR, through a comparative molecular field analysis (CoMFA) and a comparative molecular similarity indices analysis (CoMSIA) to determine the key factors for the plant growth promoting activity of brassinosteroids reported in literature, using the bean second-internode bioassay measured on two groups of compounds...

hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...

Orchardgrass (Dactylis glomerata L.) is one of the essential foraging species which used as a cool-season persistent and perennial forage grass. This research was carried out during 2019 growing season in Eastern Anatolia region Turkey. The aim our to study morphologic characteristics natural assess genetic diversity collected genotypes determine best available for future breeding programs. In ...
