Molecular basis of fruit development
نویسندگان
چکیده
The fruit is a vital plant structure that supports seed development and dispersal, and is an indispensable part of the human diet. The 11 articles within this special research topic focus on the molecular mechanisms of early fruit development and span a diversity of species and experimental approaches. Since the gynoecium, the female floral structure, is the precursor of all or part of the fruit, several articles are focused on mechanisms of gynoecium development. The articles can be organized into several groups based on common themes highlighted below.

Genetic regulation of fruit development and ripening.
Fruit development and ripening are unique to plants and represent an important component of human and animal diets. Recent discoveries have shed light on the molecular basis of developmental ripening control, suggested common regulators of climacteric and nonclimacteric ripening physiology, and defined a new role for MADS box genes in this late stage of floral development. Analyses of fruit-rip...
متن کاملSilencing GRAS2 reduces fruit weight in tomato.
GRAS family transcription factors are involved in multiple biological processes in plants. Here, we report that GRAS2 plays a vital role in regulating fruit weight in tomato (Solanum lycopersicum). We establish that the expression of GRAS2 was elevated in ovaries and maintained at a constant level in fertilized ovules. Reduction of GRAS2 expression in transgenic plants reduced fruit weight thro...
متن کاملIdentification of Linked Markers for Delayed Fruit Ripening in Tomato Using Simple Sequence Repeat (SSR) Markers
Tomato (Solanum lycopersicum L.) is an important vegetable crop and acts as model plant for fruit development studies. Besides that, post-harvest damage is a devastating phenomenon often associated with ripening process in tomato which in turn leads to greater yield loss. Understanding the genetics, molecular and biochemical pathways is the key to overcome the existing situation. In th...
متن کاملImpact of Priming by Methyl Jasmonate on Seed Germination, Growth and Development Indices and Fruit Yield in Melon Cultivars
This study was conducted having the goal of investigating the effects of Methyl Jasmonate on germination, growth and development indices and fruit yield in melon cultivars through two experiments separately performed at Labarotary and Research Station of Agricultural College, Shahid Bahonar University of Kerman in 2011. Germination test was conducted as a factorial experiment on the basis of c...
متن کاملMolecular basis for histone N-terminal methylation by NRMT1.
NRMT1 is an N-terminal methyltransferase that methylates histone CENP-A as well as nonhistone substrates. Here, we report the crystal structure of human NRMT1 bound to CENP-A peptide at 1.3 Å. NRMT1 adopts a core methyltransferase fold that resembles DOT1L and PRMT but not SET domain family histone methyltransferases. Key substrate recognition and catalytic residues were identified by mutagenes...
