Rice Trait Ontology
ID NAME DEFINITION IS_A
TO:0000001 carbon sensitivity
"Sensitivity to the carbon content in the growth medium. It plays an important role in the synthesis of various inorganic and organic metabolites such as carbohydrates, lipids, amino acids and peptides and plays a role in various metabolic processes." [Gramene:pankaj_jaiswal]
TO:0000252 ! non-mineral nutrient sensitivity
TO:0000002 epigenetic trait
"OBSOLETE. An epigenetic trait is a distinguishable feature or a characteristic or a quality of character or a phenotypic feature of a developing or developed individual but have arisen as a result of mechanisms regulating the expression of the genes rather than differences in the gene sequence." [Gramene:pankaj_jaiswal, ISBN:0198506732]
None
TO:0000003 alkali soil sensitivity
"Plant sensitivity to soils with alkali conditions (pH>7)." [IRRI:SES, TO:moorel]
TO:0000481 ! alkali sensitivity
TO:0000004 reversible male sterility
"Trait of a plant in which the action of the cytotoxic gene used to introduce male sterility is suppressed by the application of a chemical to the plant. Reversion of the sterility allows the RMS parent to be self-fertilized, a step that overcomes the need to remove fertile sib plants prior to making the hybrid cross." [PMID:10645437]
TO:0000111 ! genetically engineered male sterility
TO:0000006 calcium sensitivity
"Sensitivity to the calcium content in the growth medium. Plays an important role in cell wall synthesis and enzyme activities." [Gramene:pankaj_jaiswal]
TO:0000251 ! secondary macronutrient sensitivity
TO:0000007 sulfur sensitivity
"Response by the plant in terms of sensitivity to sulfur content in the growth medium. It is important for synthesis of some amino acid residues." [Gramene:pankaj_jaiswal]
TO:0000251 ! secondary macronutrient sensitivity
TO:0000008 potassium sensitivity
"Sensitivity to the potassium ion content in the growth medium. It plays an important role in controlling water by osmosis and also in the metal ion homeostasis." [Gramene:pankaj_jaiswal]
TO:0000248 ! primary macronutrient sensitivity
TO:0000009 genic male sterility-photoperiod sensitive
"Male sterility affected by photoperiod." [Gramene:pankaj_jaiswal, IRRI:SES]
TO:0000199 ! genic male sterility
TO:0000010 magnesium sensitivity
"Sensitivity to the magnesium content in the growth medium. It is important for chlorophyll biosynthesis and metal ion homeostasis." [Gramene:pankaj_jaiswal]
