8 Cana-de-açúcar Cultivada em mais de 90 países
Ocupando cerca de 20 milhões de hectares Família das Gramíneas (Poace) Sugarcane is an important industrial crop of tropical and subtropical regions cultivated in more than 90 countries over close to 20 millions hectares (FAO - It belongs to the grass family (Poaceae), an economically important seed plant family that includes cereals like maize, wheat, rice and sorghum as well as many forage crops.

25% da produção mundial 300 milhões de tons. 5 milhões de hectares plantados 14.5 milhões de tons. de açúcar 15.3 bilhões de litros de álcool 350 industrias 50 mil produtores 1.4 milhões de empregos direto 3.6 milhões de empregos indiretos

C Proc Int Soc Sugarcane Technol 24: conjunto não-reduntante = 930 Mbp Sorgo = 760 Mbp Arroz = 430 Mbp The non-replicated genome size of a somatic sugarcane cell (2C) is estimated to be 7,440 mega base-pairs (Mbp) in S. officinarum. Since S. officinarum is octaploid, the size of a complete nonredundant chromosome set should be eight-fold smaller, around 930-Mbp (D'Hont and Glaszmann 2001) This value is comparable to that of sorghum (~ 760-Mbp) and about twice that of rice (~ 430-Mbp) D'Hont, A. and Glaszmann, J.

Examination of the primary BLAST matches revealed 3 major groups of SAS with varying potential to predict their cellular function, SAS in the first group. matching sequences of known proteins with strong and nominal similarity. are likely to be transcripts of genes with similar functions ( SAS; 36%), The function of the BLAST match was used to assign cellular roles to this group, The second class is formed by 15% of the total SAS (6.614 or 24,9% of the categorized SAS in Figure 1) and this group matched to ‘unknown protein’. ‘hypothetical protein’ or ‘putative protein’ with no indication of the function of the gene product, Most of these were ESTs from other species that had been entered into the GenBank non-redundant database, In the third group are the SAS (35.6% of the total SAS) with no matches in the GenBank nr database, Almost 50% of all SAS annotated in the SUCEST are associated with five broad role categories: (1) Cellular dynamics (Biogenesis. organization and structure of the cell. Cell division. Cell growth. Motility); (2) stress response (cell rescue activities. disease. virulence and defense); (3) protein metabolism (folding and stabilization. modification. synthesis. targeting. sorting and translocation. proteolysis); (4) bioenergetics (C‑compound and carbohydrate metabolism. photosynthesis) and (5) cellular communication/signal transduction (Figure 1),

50 Porcentagem por órgão The 26 SUCEST cDNA libraries where grouped according to the sugarcane organs used as source for mRNA extraction, Infected Plantlets (AD1. HR1). Meristem (AM1. AM2. LB1. LB2). Callus (CL6). Inflorescence (FL1. FL3. FL4. FL5. FL8). Leaf (LV1. LR1. LR2). Root (RT1. RT2. RT3). Seed (SD1. SD2). Stalk (ST1. ST3. SB1. RZ1. RZ2. RZ3), The abundance of transcripts in each category was calculated dividing the number of high quality sequences in each category by the total number of high quality sequences in each organ (the sum of high quality sequences in each library associated with the plant organ – Table 2 (???) Supplementary Material), Average percentage of SAS per category does not add to 100% because some SAS appear in more than one category, SD is standard deviation,

Uma das plantas em estudo é a Medicago truncatula (uma luzerna anual, leguminosa pratense utilizada na produção de alimento em fresco ou para forragem para gado). Esta planta, em condições adequadas, sofre um processo de diferencia- ção in vitro denominado de Embriogénese Somática. Neste processo, as célu- las dos folíolos desta planta multiplicam-se, dando origem a células capazes de, por multiplicação e diferenciação, darem origem a embriões, em tudo idên- ticos aos originados por desenvolvimento de um zigoto (resultante da fusão do grão de pólen germinado com o óvulo).
