LAP3, a novel plant protein required for pollen development, is essential for proper exine formation [PDF]
, 2009 We isolated lap3-1 and lap3-2 mutants in ascreen for pollen that displays abnormal stigma binding.Unlike wild-type pollen, lap3-1 and lap3-2 pollen exine isthinner, weaker, and is missing some connections betweentheir roof-like tectum structures.

On the friction coefficient of straight-chain aggregates
, 2011 A methodology to calculate the friction coefficient of an aggregate in the continuum regime is proposed. The friction coefficient and the monomer shielding factors, aggregate-average or individual, are related to the molecule-aggregate collision rate ...

Dual selection enhances the signaling specificity of a variant of the quorum-sensing transcriptional activator LuxR [PDF]
, 2006 The transcription factor LuxR activates gene expression in response to binding the signaling molecule 3-oxo-hexanoyl-homoserine lactone (3OC6HSL), an acyl-HSL with a carbonyl substituent at the third carbon of the acyl chain.

Modular pathway engineering for the microbial production of branched-chain fatty alcohols
Biotechnology for Biofuels, 2017 The intrinsic structural properties of branched long-chain fatty alcohols (BLFLs) in the range of C12 to C18 make them more suitable as diesel fuel replacements and for other industrial applications than their straight-chain counterparts. While microbial

The Chromatic Number of the Disjointness Graph of the Double Chain [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 Let $P$ be a set of $n\geq 4$ points in general position in the plane. Consider all the closed straight line segments with both endpoints in $P$. Suppose that these segments are colored with the rule that disjoint segments receive different colors.

Detection of a branched alkyl molecule in the interstellar medium: iso-propyl cyanide
, 2014 The largest non-cyclic molecules detected in the interstellar medium (ISM) are organic with a straight-chain carbon backbone. We report an interstellar detection of a branched alkyl molecule, iso-propyl cyanide (i-C3H7CN), with an abundance 0.4 times ...

n-Hosoya polynomials for Pentagonal Chains [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 The diameter, with respect to the n-distance of the graph which represents a straight chain consisting of m pentagonal rings, is obtained in this paper. The n-Hosoya polynomial of , for all m and n, where , is also obtained.

Oléagineux, Corps gras, Lipides, 2001 Nutritional values of fatty acid classes are normally discussed on the basis of their saturated, monounsaturated and polyunsaturated structures with implicit understanding that they are straight-chain.

Kinetically driven helix formation during the homopolymer collapse process
, 2008 Using Langevin simulations, we find that simple 'generic' bead-and-spring homopolymer chains in a sufficiently bad solvent spontaneously develop helical order during the process of collapsing from an initially stretched conformation.

Curvature-induced symmetry breaking in nonlinear Schrodinger models [PDF]
, 2000 We consider a curved chain of nonlinear oscillators and show that the interplay of curvature and nonlinearity leads to a symmetry breaking when an asymmetric stationary state becomes energetically more favorable than a symmetric stationary state. We show
