A radiation-induced mutation of cucumber (Cucumis sativus L.) which affects plant pubescence is controlled by a single recessive gene. Mutant seedlings have glabrous hynocotyls, and mature plants have glabrous internodes and leaf petioles. The laminae, especially of the first true leaf, the node areas and the perianths are slightly pubescent (glabrate). This new gene is designated glb, glabrate. There was no evidence of linkage between this gene and glabrous (gl), non-bitter cotyledon (bi), light sensitive (ls), yellow cotyledon (yc) or crinkled-leaf (cr).A sister line of glb also segregated for a lethal mutation. Mutant seedlings had pale green, slightly smaller cotyledons, and died 6 to 7 days after emergence. The mutation was controlled by a single recessive gene, designated pl, pale lethal. The gene was not linked with either glabrate (gib) or non-bitter cotyledon (bi).

Floral Organ Specification

SUMMARYFloral organ development influences plant reproduction and crop yield. The mechanism of floral organ specification is generally conserved in angiosperms as demonstrated by the ‘ABC’ model. However, mechanisms underlying the development of floral organs in specific groups of species such as grasses remain unclear. In the genus Oryza (rice), a spikelet consists of a fertile floret sub-tended by a lemma, a palea, two sterile lemmas and rudimentary glumes. To understand how the lemma is formed, a curve-shaped lemma-distortion1 (ld1) mutant was identified. Genetic analysis confirmed that the ld1 mutant phenotype was due to a single recessive gene mutation. Using a large F2 population, the LD1 gene was mapped between markers Indel-7-15 and Indel-7-18, which encompassed a region of 15·6 kilo base pairs (kbp). According to rice genome annotations, two putative genes, LOC_Os07g32510 and LOC_Os07g32520, were located in this candidate region. However, DNA sequencing results indicated only 1 base pair (bp) substitution (T⇨C) was found in LOC_Os07g32510 between the wild-type and the ld1 mutant. Thus LOC_Os07g32510, encoding a DNA binding with one zinc finger (DoF) containing protein, was the candidate gene for LD1. Further analysis showed that mutation of the amino acid cysteine (C) to arginine (R) was likely to lead to zinc finger protein deactivation. Phylogenetic and conservation analysis of the gene from different species revealed that cysteine was critical to LD1 function. As a new gene controlling lemma development, the study of LD1 could provide insights into rice floral organ formation mechanisms.

SUMMARYAn induced mutant of rice, designated M41, resistant to several races of bacterial leaf blight, obtained after irradiation with thermal neutrons, was crossed with the original variety, Harebare. Test crosses revealed that the resistance of M41 to the Japanese races I, II, III and IV is controlled by a single recessive gene, considered to be different from four previously identified dominant resistance genes of japonica-type varieties and from three recessive genes in indica-type varieties for resistance to Philippine races. The gene in M41 was tentatively designated xa-nm(t).

The genetics of two radiation-induced mutants of cv. Moneymaker, "easy peeling" and "oblong fruit with strong skin", were studied. Both were governed by a single recessive gene. The combination of both traits was achieved by crossing, but it was impossible to break the association between oblong fruit and strong skin. Hybrid easy peeling material with round or oblong fruit shape was selected for yield and improvements up to 30% over Moneymaker were reached under experimental conditions. The easy peeling trait may be of interest both for the canning industry and for fresh consumption.-Univ. Wageningen & Neth. Inst. atomic Sci. Agric.

Zucchini yellow fleck virus (ZYFV) is a potyvirus that occurs in cucurbits grown in some Mediterranean countries. `Marketer' cucumber responded to ZYFV infection with a severe mosaic, stunting, and leaf and fruit deformation. A high level of resistance to this virus was found in a single plant selection of `Taichung Mou Gua' (TMG) cucumber from Taiwan. In F2 and backcross populations involving TMG × `Marketer', the resistance to ZYFV was determined to be conferred by a single recessive gene, to which the symbol zyf is assigned.

Pink seed, which germinated faster than normal seed and gave albino seedlings with a pinkish color, segregated from all selfed fruit from plants of cucumber (Cucumis sativus L.) heterozygous for a radiation-induced translocation. The segregation ratio in some populations suggested monogenic, recessive inheritance. No pink seed or pink albino mutants segregated from fully fertile progeny of translocation heterozygotes and no homozygous translocation lines were found. It is suggested that the lethal albino mutation is associated with the induced interchange.
