Polymorphism of floral signals, such as colour and odour, is widespread in flowering plants and often considered to be adaptive, reflecting various pollinator preferences for particular floral traits. Several authors have recently hypothesized that particular associations exist between floral colour and scent, which would result from shared biochemistry between these two floral traits. In this ...

Although many genes that regulate floral development have been identified in Arabidopsis thaliana, relatively few are known in the grasses. In normal maize (Zea mays), each spikelet produces an upper and lower floral meristem, which initiate floral organs in a defined phyllotaxy before being consumed in the production of an ovule. The bearded-ear (bde) mutation affects floral development differ...

Recent research on how the structure and physiological development of red raspberry (Rubus idaeus L.) plants are controlled by genotype and the climatic environment is reviewed. Some older work, especially on plant structure relations, is also included. Physiological differences between annualand biennial-fruiting plant types are highlighted. One major difference is the different requirements f...

The study aimed to determine the evapotranspiration (ETc) of mango cv. ‘Palmer’ over two productive cycles, analyzing water-use efficiency (WUE) and crop water productivity (CWP) propose average coefficient (Kc) values for improving irrigation management under cultivation conditions in Low-Middle São Francisco Valley. was conducted from July 2019 May 2021 a commercial orchard Petrolina, State P...

Application of the plant growth regulator paclobutrazol (PBZ) to aid mango floral induction has been widely performed by producers. However, its application done manually, resulting in low uniformity and losses with labor. The objective this study was adjust PBZ dose be applied via micro-sprinkler system for induction, indicating an efficient management ‘Palmer’ Brazilian semiarid. experiment c...

The control of floral organ identity by homeotic MADS box genes is well established in eudicots. However, grasses have highly specialized outer floral organs, and the identities of the genes that regulate the highly specialized outer floral organs of grasses remain unclear. In this study, we characterized a MIKC-type MADS box gene, CHIMERIC FLORAL ORGANS (CFO1), which plays a key role in the re...

Floral organogenesis requires coordinated interactions between genes specifying floral organ identity and those regulating growth and size of developing floral organs. With the aim to isolate regulatory genes linking both developmental processes (i.e., floral organ identity and growth) in the tomato model species, a novel mutant altered in the formation of floral organs was further characterize...
