1 Genetic and molecular basis of chlorophyll retention in soybean seed Henk Hilhorst, Wageningen University, Edvaldo A Amaral da Silva Universidade Estadual Paulista (FCA) Collaborators in Brazil: José França-Neto Fernando Henning Francisco Carlos Krzyzanowski

3 The green seed problem Yellow seeds Green seeds Reported for many years Impairment of chlorophyll degradation Mature/ripe seeds remain green
4 Why is chlorophyll retention a problem to be World Soybean Production in 2012 considered? Big losses for growers Frequently reported soybean and canola (Brassica napus) Global climate changes Introduction of soybean to low latitudes Brazil 2º largest soybean producer Breeding programs Source: targetmap.com world soybean production.
5 Normal conditions Chlorophyll is completely degraded during maturation
6 Causes of Chlorophyll Retention High temperatures Drought Severe rust Chemical desiccants + Genetic Components nd nd nd = not detected
7 Presence of chlorophyll in seeds = lower seed quality Viability Vigor Longevity (storability)
8 Presence of chlorophyll in seeds = lower oil quality Green Seeds: Reduction of up to 3 % point of total amount of oil Higher acidity Higher refining cost Lower quality in storage light - oxidation Oxidation of the oil is influenced by the composition of fatty acids, oil processing, light, temperature, concentration and type of oxygen, free fatty acids, mono and diacylglycerols, transition metals, peroxides, thermally oxidized compounds, pigments and antioxidants.
9 Chlorophyll (mg/kg) Oxidative Stability 110 C (h) Example: Cultivar W799 Tocopherols and Tocotrienols (mg/100g) Green Seeds Yellow Seeds Green Seeds Yellow Seeds
10 Oil quality MINISTÉRIO DA AGRICULTURA, PECUÁRIA E ABASTECIMENTO IN Nº 49, of DECEMBER 22, 2006 (BRASIL, 2006): define the characteristics of identity and quality of refined vegetable oils. Sensory characteristics, color, impurities, composition of fatty acids, stability index, peroxide index, unsaponifiable matter, smoke point, etc... IN Nº 11, of MAY 15, 2007 (BRASIL, 2007): establish the Soybean Technical Regulation. Green Seed In-natura consumption: up to 4% Other uses: up to 8%
11 How to address the green seed problem?
12 Some research questions 1. Does chlorophyll directly affect soybean seed quality? Or is it just a marker for the stage of seed ripening? 2. Why do seeds have chlorophyll, if it is potentially damaging? Biological role? 3. Can we dissect the environmental from the genetic causes of green seeds?
13 Approaching the Green Seed Problem STEP 4 Molecular markers for breeding/genes for genetic modification STEP 1 Chlorophyll vs seed/oil quality STEP 3 Molecular control of chlorophyll degradation STEP 2 Molecular characterization of chlorophyll retention
14 Some details of experimental approach Environmental vs. genetic component (genotype) of seed and oil quality
15 42 Lots/13 cultivars of soybean were harvested in different regions and climatic conditions of Brazil Percentage of green seeds was determined (any sign of green color the seeds were classified as green )
16 First selection From 42 Lots 24 Lots For example: Seed lots with the highest and the lowest percentage of green seeds from each cultivar were selected. CV SYN1059 RR Lot Place % Green Seeds Lot 1 SC R CRISTALINA-GO 12 Lot 2 SC R CRISTALINA-GO 21 Lot 3 SC A CRISTALINA-GO 3 Lot 7 SC A IPAMERI-GO 5

18 Seed lots with higher percentage of green seeds Lower germination Correlation Germination (%) x Green Seeds (%) r: >8% < 8% More than 8% Until 8% 80 Germination (%) Green Seeds (%)
19 Second Component (19,2%) Green and yellow seeds Significant difference in seed quality PC1 and PC2 explained 93% of the variation. Germination (%) Normal Seedlings (%) Abnormal Seedlings (%) Dead Seeds (%) Root Lenght (cm) Shoot Lenght (cm) First Component (73,8%)

24 Experimental setup molecular approach 2 Cultivars Susceptible X Tolerant X Harvesting 3 Stages of Maturation 2 Environmental Conditions Non-stressed X Stressed (heat and drought) Characterization of Green Seed Production Chlorophyll Content Seed Quality R6 R7 R8 Gene Expression
25 Multiple gene ontologies were enriched in soybean seeds produced under stress. Among the top-ranking ontologies was the photosynthetic process. Expression analysis suggests higher levels of the photosynthetic proteins D1, D2, A1 and A2 in stressed/green seeds. NYC1_1, PPH2, D1 and D2 are the most affected genes in stressed/green seeds of the susceptible cultivar and may be the major cause of the chlorophyll retention in soybean seeds.
26 Main conclusion Higher expression of SGR1 (D1), SGR2 (D2), NYC1_1 and PPH2 in fully mature seeds of the tolerant cultivar allows these seeds to cope with stressful conditions and complete chlorophyll degradation.
