Abstract:
... Screening for agronomic traits associated with grain moisture is important for mechanical grain-harvesting of maize. Cob color as a visual indicator has received limited attention, though it has been subjected to artificial selection, and may have some association with threshability. To investigate the relationships between cob color and grain moisture and other agronomic traits, field experiments ...

Abstract:
... Through the inactivation of genes that act during meiosis it is possible to direct the genetic make‐up of plants in subsequent generations and optimize breeding schemes. Offspring may show higher recombination of parental alleles resulting from elevated crossover (CO) incidence, or by omission of meiotic divisions, offspring may become polyploid. However, stable mutations in genes essential for re ...

Abstract:
... There is little consistency on effects of ramet physical connection in homogeneous environments. To revisit this issue, we chose Cynodon dactylon (Linn.) Pers. (Bermuda grass) as a model plant to establish three experiments. In the water availability experiment (I), stolon severing had no significant effects on plant biomass; however, it significantly affected plant morphology by increasing main s ...

Abstract:
... The role of auxin in plant–microbe interaction has primarily been studied using indole-3-acetic acid (IAA)-producing pathogenic or plant-growth-promoting bacteria. However, the IAA biosynthesis pathway in bacteria involves indole-related compounds (IRCs) and intermediates with less known functions. Here, we seek to understand changes in plant response to multiple plant-associated bacteria taxa and ...

Abstract:
... Parasitic flowering plants are characterized by the development of an organ known as haustorium, which has evolved in multiple independent angiosperms clades. The haustorium has also been deemed “the most plastic of organs” due to its ability to accommodate physiological and anatomical differences between the parasite itself and its host plants. This is achieved through the development of vascular ...
