Abstract:

The development of male gametophytes in diploid and monosomic-1, -2, -3, -4, -6, -7, -8, -9, and -10 maize plants was characterized. Developmental differences due to nullisomy in the gametophyte were evaluated by comparing the development of haploid and nullisomic microspores formed by monosomic plants, while differences due to gene dosage in the sporophyte were evaluated by comparing the development of haploid microspores in monosomic plants with those in diploids. These analyses show that (i) male gametophytes nullisomic for the chromosomes analyzed are developmentally delayed and eventually

Abstract Abstract 3537 Objectives: Cytogenetics is one of the most important prognostic factors in acute myeloid leukemia (AML). Breems et al., based on banding techniques (BT), have identified a monosomal karyotype (MK) to be associated with particularly poor survival. MK is defined by the presence of an autosomal monosomy in conjunction with at least one other autosomal monosomy or structural abnormality. However, classical BT may be not sufficient to confirm the “real” loss of a particular chromosome, especially in patients with complex karyotype (≥ 3 or ≥ 5 separate abnormalities) where pa

Abstract:

Abstract Abstract 2745 Background: The influence of cytogenetic abnormalities on the prognosis of acute myeloid leukemia (AML) has been well-documented; however, the relative impact of certain miscellaneous abnormalities remains controversial. Recently, monosomal karyotype-based risk stratification has been shown to further discriminate the prognosis within the poor-risk karyotype group (Breems et al. JCO 2008), but this finding requires further validation. Methods: We retrospectively reviewed 779 consecutive adult AML patients treated with standard induction chemotherapy, consisting of daunor

Abstract:

Abstract Abstract 4867 Background: A monosomal karytype (MK) is defined by the presence of at least two or more distinct autosomal monosomies or an autosomal monosomy along with a structural defect. In AML this cytogenetic pattern has a very well-known poor prognostic significance independently of the specific chromosome involved. Currently, in MDS this negative prognostic influence is also emerging as recent data suggest that any monosomy in a complex karyotype (≥3 abnormalities) may have the same poor prognostic impact as monosomy 5 and 7 (−5,−7). Objectives: Thus, the principal goal of the

Abstract Abstract 1473 The incidence of the secondary neoplasms has increased because of the rising numbers of long-term survivors of tumours. Secondary leukemias (sL) and secondary MDS (sMDS) are among the most common types of secondary tumours. Until recently prognosis in cases of sL and sMDS was considered less favorable than in leukemias de novo. Age at presentation and identified clonal cytogenetic abnormalities are among the most important independent prognostic factors in adult patients with leukemias. It is obvious today that the presence of t(15;17)(q22;q12), t(8;21)(q22;q22), inv(16)

Abstract:

Plants of allotetraploid cotton, Gossypium hirsutum L. (2n = 4x = 52), which are monosomic for chromosome 9 or haplodeficient for the long arm of the chromosome, an Ah genome chromosome, produce a high frequency of aneuploid progeny. The aneuploids include monosomes, trisomes, and multiple monosomic and trisomic combinations that are the result of chromosome nondisjunction, which is induced by the deficiency of the long arm of chromosome 9. Loss of chromosomes occurs far more frequently than additions, and chromosomes of the Ah genome undergo nondisjunction at a significantly greater rate than

Abstract Introduction Hyperhaploid multiple myeloma is a rare numerical aberration group defined by a range of 24-34 chromosomes. We have previously shown that hyperhaploid myeloma is associated with a poor prognosis with a 5-year survival rate of 23.1%, compared to 64% for hyperdiploid myeloma, and 80.4% for those with a normal karyotype. It is known that hyperhaploid myeloma frequently has monosomy of chromosome 17, making it a high risk group, but no data are currently available on the mutational status of this interesting sub-group, or how the copy number difference arises.

Abstract Abstract 4154 Background: Monosomal karyotype (MK) has been defined as the presence of two or more autosomal monosomies or of a single monosomy associated with at least one structural abnormality (Breems et al, JCO 2008). The presence of MK has been associated with extremely poor prognosis in patients with not only acute myeloid leukemia (AML) but myelodysplastic syndrome (MDS) (Patnaik et al, Leukemia 2011). Our goal was to investigate the efficacy of allogeneic hematopoietic stem cell transplantation (HSCT) for myeloid malignancies with MK. Patients and methods: We combined data fro

Abstract Abstract 1003 Poster Board I-25 Introduction: Recently, the cooperative group HOVON-SAKK has refined the prognostic impact of cytogenetic abnormalities in acute myeloid leukemia (AML) by introducing the concept of monosomal karyotype (MK). This consists of ≥ 2 autosomal monosomies or one autosomal monosomy in addition to a structural alteration. In their experience, MK would explain the poor prognosis of AML with a complex karyotype. Objective: To investigate the prognostic impact of MK in patients with primary (de novo) AML enrolled in the Spanish CETLAM group protocols (AML 94/99/03

Abstract:

Intumescent leaf variants of sugar beet (Beta vulgaris L.) were obtained through callus culture of a monosomic addition that carried resistance to Heterodera schachtii Schm. The frothy pockmarked appearance of the leaf surface was due to hyperplastic growth of the mesophyll and epidermal cells. The epidermis had many malformed stomata. Veins were underdeveloped, but protrusions beneath were pronounced. Intumescence occurred in 20.3% of the regenerated plants and it was heritable to F1 and later progeny. Leaf intumescence is a new phenotype for Beta. About 73.5% of regenerants contained the don
